Description

Technical Field

[0001] This disclosure relates to the field of computer design, and more particularly to a method, apparatus, device, and storage medium for inserting views into drawings. Background Technology

[0002] In existing design software, such as Revit, drawings are typically generated that insert various views of an object, which usually includes components and annotation information located outside the components.

[0003] However, in drawings generated by existing design software, the outer contours of component projections in different views, such as the vertices or top edges of component projections in the left and right views, cannot be aligned. This makes it easy for technicians to make mistakes when processing and interpreting the drawings, and also affects the aesthetics of the drawings. Summary of the Invention

[0004] According to a first aspect of this disclosure, a method for inserting a view within a drawing is provided, the method comprising:

[0005] Obtain the initial insertion point of each of the multiple views to be inserted in the target object within the drawing. The multiple initial insertion points corresponding to the multiple views to be inserted are arranged along a preset direction. The target object includes a target component and annotation information located outside the target component. The initial insertion point is the initial insertion position of the two-dimensional midpoint of the view within the drawing. The two-dimensional midpoint of the view is the center of the minimum bounding box of the view.

[0006] Determine the offset vector corresponding to each view. The offset vector is used to characterize the relative positional relationship between the two-dimensional midpoint of the view and the two-dimensional midpoint of the target component within the view. The two-dimensional midpoint of the target component is the center of the minimum bounding box of the target component.

[0007] Based on the initial insertion point and offset vector corresponding to each view, the target insertion point corresponding to each view is determined in the drawing. The target insertion point is the target insertion position of the two-dimensional midpoint of the view in the drawing.

[0008] Each view is inserted into the drawing based on the target insertion point corresponding to each view.

[0009] According to a second aspect of this disclosure, an apparatus for inserting views within a drawing is provided, the apparatus comprising:

[0010] The initial insertion point determination module is used to obtain the initial insertion point of each of the multiple views to be inserted of the target object in the drawing. The multiple initial insertion points corresponding to the multiple views to be inserted are arranged along a preset direction. The target object includes a target component and annotation information located outside the target component. The initial insertion point is the initial insertion position of the two-dimensional midpoint of the view in the drawing. The two-dimensional midpoint of the view is the center of the minimum bounding box of the view.

[0011] An offset vector determination module is used to determine the offset vector corresponding to each view. The offset vector is used to characterize the relative positional relationship between the two-dimensional midpoint of the view and the two-dimensional midpoint of the target component within the view. The two-dimensional midpoint of the target component is the center of the minimum bounding box of the target component.

[0012] The target insertion point determination module is used to determine the target insertion point corresponding to each view in the drawing based on the initial insertion point and offset vector corresponding to each view. The target insertion point is the target insertion position of the two-dimensional midpoint of the view in the drawing.

[0013] The insertion module is used to insert each view into the drawing based on the target insertion point corresponding to each view.

[0014] According to a third aspect of this disclosure, an electronic device is provided, comprising: a processor; and a memory storing a program, wherein the program includes instructions that, when executed by the processor, cause the processor to perform the method according to a first aspect of this disclosure.

[0015] According to a fourth aspect of this disclosure, a non-transitory computer-readable storage medium is provided storing computer instructions, wherein the computer instructions are configured to cause the computer to perform the method described according to a first aspect of this disclosure.

[0016] According to a fifth aspect of this disclosure, a computer program product is provided, comprising a computer program, wherein the computer program, when executed by a processor, implements the method described in accordance with a first aspect of this disclosure.

[0017] One or more technical solutions provided in this disclosure involve obtaining the initial insertion point of each of the multiple views to be inserted into the target object within the drawing. The initial insertion points of each view are arranged along a preset direction. Each insertion point is the initial insertion position of the two-dimensional midpoint of the view within the drawing, and this two-dimensional midpoint is the center of the view's minimum bounding box. Then, an offset vector is determined for each view, representing the relative positional relationship between the two-dimensional midpoint of the view and the two-dimensional midpoint of the target component within the view. Based on the initial insertion point and offset vector of each view, the target insertion point for each view is obtained. Based on the target insertion points of each view, the respective views are inserted into the drawing. Thus, the two-dimensional midpoints of the target components in the inserted views are arranged along the preset direction, meaning the outlines of the target components in each view are aligned based on the preset direction, making the drawing more aesthetically pleasing and easier for technicians to process and interpret.

[0036] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0037] Figure 1 Flow of a method for inserting a view within a drawing provided as an exemplary embodiment of this disclosure Figure 1 ,like Figure 1 As shown, it includes the following steps:

[0038] S101. Obtain the initial insertion point of each of the multiple views to be inserted in the drawing. The multiple initial insertion points of the multiple views to be inserted are arranged along a preset direction. The target object includes the target component and the annotation information located outside the target component. The initial insertion point is the initial insertion position of the two-dimensional midpoint of the view in the drawing. The two-dimensional midpoint of the view is the center of the minimum bounding box of the view.

[0039] In this embodiment of the disclosure, the target object includes the target component and the annotation information on the outside of the target component, which includes at least one of text annotation or dimension annotation.

[0040] This drawing is a graphical representation of engineering practices, showing dimensions, orientations, and technical parameters required for construction. When generating this drawing, various views of the target object are inserted into it. These views are projections of the target object onto a projection plane using orthographic projection. Common views include the front view, left view, right view, top view, and bottom view. Typically, each view has its own independent coordinate system.

[0041] The embodiments disclosed herein do not limit the number of views to be inserted. For example, the number of views to be inserted may be three, such as the front view, left view and right view of the target object, or the front view, top view and bottom view of the target object; or, for example, the number of views to be inserted may be five, such as the front view, left view, right view, top view and bottom view of the target object.

[0042] In this embodiment, the initial insertion point is the initial insertion position of the two-dimensional midpoint of the corresponding view within the drawing, i.e., the two-dimensional midpoint of the corresponding view, which is the center of the view's minimum bounding box. This minimum bounding box, also known as the minimum circumscribed rectangle, is a rectangle defined by the maximum, minimum, maximum, and minimum abscissas of all contents in the view. The minimum bounding box includes all contents in the view, such as target components, text annotations, and dimension annotations. The center coordinates of the minimum bounding box can be calculated based on the aforementioned maximum, minimum, maximum, and minimum abscissas. The center abscissa of the bounding box is the average of the aforementioned maximum and minimum abscissas, and the center ordinate of the bounding box is the average of the aforementioned maximum and minimum ordinates.

[0043] In this embodiment, the initial insertion points of multiple views to be inserted are arranged along a preset direction, that is, the initial insertion points of multiple views to be inserted are aligned along a preset direction. This embodiment does not particularly limit the preset direction. In one embodiment, the preset direction is a single direction, that is, the multiple initial insertion points are arranged along this single direction. For example, when the views to be inserted are a left view, a front view, and a right view, their corresponding initial insertion points are arranged along a single direction; when the views to be inserted are a top view, a front view, and a right view, their corresponding initial insertion points are also arranged along a single direction.

[0044] In another embodiment, the preset direction is two mutually perpendicular directions, such as a first direction and a second direction. Some of the multiple initial insertion points are arranged along the first direction, and others are arranged along the second direction. For example, when the view to be inserted is a left view, a front view, a right view, a top view, and a bottom view, the initial insertion points corresponding to the left view, the front view, and the right view are arranged along the first direction, and the initial insertion points corresponding to the top view, the front view, and the bottom view are arranged along the second direction.

[0045] Figure 2 A schematic diagram of the initial insertion point corresponding to the view to be inserted, provided as an exemplary embodiment of this disclosure, such as... Figure 2As shown, there are five initial insertion points within drawing 21: 221 for the left view, 222 for the front view, 223 for the right view, 224 for the top view, and 225 for the bottom view. Initial insertion points 221, 222, and 223 are arranged along a first direction, while initial insertion points 224, 222, and 225 are arranged along a second direction, with the first direction perpendicular to the second direction. The dashed boxes 231, 232, 233, 234, and 235 represent the viewports of the left, front, right, top, and bottom views after insertion into the drawing, respectively. Each viewport is a rectangular frame formed by the inserted view and can be considered the minimum bounding box of the view. The initial insertion point is the minimum bounding box, i.e., the center of the viewport. It should be noted that in step S101, no view is actually inserted into the drawing. The dashed boxes are used to indicate the viewports of the views to be inserted to show the relative positions of the views after insertion based on the initial insertion points. from Figure 2 It can be seen that the top and bottom edges of the viewports of the left, front, and right views are aligned in the first direction, while the left and right edges of the viewports of the top, front, and bottom views are aligned in the second direction. Since the target object includes the target component and its external annotations, and these annotations are not typically symmetrically distributed along the sides of the target component, the 2D midpoint of the view and the 2D midpoint of the target component within that view often do not coincide. Therefore, when the sides of the viewports of each view are aligned based on the first and second directions, the sides of the target component within each view cannot be aligned based on the first and second directions. Figure 3 As shown, the bottom edges (the lowest vertices) and top edges (or the highest vertices) of the target component in the left, front, and right views are not aligned in the first direction. Similarly, the left edges (or the leftmost vertices) and right edges (or the rightmost vertices) of the target component in the top, front, and right views are not aligned in the second direction. This results in unsightly drawings and makes it easy for technicians to make mistakes during manufacturing.

[0046] This disclosure does not limit the method of obtaining the initial insertion point corresponding to the view to be inserted. For example, an initial insertion point can be set for the view to be inserted based on its type. For example, for the left view, an initial insertion point is assigned to it in a left-hand position, and for the right view, an initial insertion point is assigned to it in a right-hand position. The distance between each initial insertion point can be preset in advance.

[0047] However, it is not limited to this; in another feasible approach, such as... Figure 4 As shown, obtaining the initial insertion point of each of the multiple views to be inserted into the target object within the drawing includes the following steps:

[0048] S401. Get the size of the minimum bounding box for each view.

[0049] The minimum bounding box is a rectangle defined by the maximum and minimum x-coordinates, maximum and minimum y-coordinates of all contents in the view. The width of the minimum bounding box can be obtained by using the maximum and minimum x-coordinates in the view, and the height of the minimum bounding box can be obtained by using the maximum and minimum y-coordinates in the view.

[0050] S402. Obtain the initial insertion point corresponding to the first view, which is any one of multiple views to be inserted.

[0051] The initial insertion point corresponding to the first view is preset. In this step, the preset initial insertion point corresponding to the first view is obtained. The embodiments of this disclosure do not limit the type of the first view. For example, it can be any one of the following: left view, front view, right view, top view, bottom view, and rear view.

[0052] S403. Based on the initial insertion point corresponding to the first view and the size of the minimum bounding box of each view, determine the initial insertion points corresponding to other views among the multiple views to be inserted, wherein the other views are the views other than the first view among the multiple views to be inserted.

[0053] In one specific embodiment, the views to be inserted include a left view, a front view, a right view, a top view, and a bottom view, with the first view being the left view. Based on the initial insertion point corresponding to the first view and the size of the minimum bounding box of each view, the initial insertion points corresponding to the other views among the multiple views to be inserted are determined, such as... Figure 5 As shown, it includes the following steps:

[0054] S501. Move the initial insertion point corresponding to the first view along the first direction by a first distance to obtain the initial insertion point corresponding to the main view. The first distance is related to the size of the minimum bounding box of the first view and the size of the minimum bounding box of the main view.

[0055] In one example, the main view is placed to the right of the left view. After the initial insertion point corresponding to the left view is determined, the initial insertion point corresponding to the left view is moved to the right by a first distance to obtain the initial insertion point corresponding to the main view. This first distance is determined based on the size of the minimum bounding box of the left view and the size of the minimum bounding box of the main view. In a specific example, this first distance is half the width of the minimum bounding box of the left view, plus half the width of the minimum bounding box of the main view, plus a fixed value, which can be preset.

[0056] In other examples, the main view can also be set to the left of the left view. In this case, the initial insertion point corresponding to the left view should be moved to the left by a first distance to obtain the initial insertion point corresponding to the main view.

[0057] S502. Move the initial insertion point corresponding to the main view along the first direction by a second distance to obtain the initial insertion point corresponding to the right view. The second distance is related to the size of the minimum bounding box of the main view and the size of the minimum bounding box of the right view.

[0058] In one example, the right view is placed to the right of the main view. After the initial insertion point corresponding to the main view is determined, the initial insertion point corresponding to the main view is moved to the right by a second distance to obtain the initial insertion point corresponding to the right view. This second distance is determined based on the size of the minimum bounding box of the main view and the size of the minimum bounding box of the right view. In a specific example, this second distance is half the width of the minimum bounding box of the main view, plus half the width of the minimum bounding box of the right view, plus a fixed value, which can be preset.

[0059] In other examples, the right view can also be set to the left of the main view. In this case, the initial insertion point corresponding to the main view should be moved to the left by a second distance to obtain the initial insertion point corresponding to the right view.

[0060] S503. Move the initial insertion point corresponding to the main view along the second direction by a third distance to obtain the initial insertion point corresponding to the top view. The third distance is related to the size of the minimum bounding box of the main view and the size of the minimum bounding box of the top view. The second direction is perpendicular to the first direction.

[0061] In one example, the top view is positioned above the main view. After the initial insertion point corresponding to the main view is determined, the initial insertion point of the main view is moved upwards by a third distance to obtain the initial insertion point of the top view. This third distance is determined based on the dimensions of the minimum bounding box of the main view and the minimum bounding box of the top view. In a specific example, this third distance is half the height of the minimum bounding box of the main view, plus half the height of the minimum bounding box of the top view, plus a fixed value that can be preset.

[0062] In other examples, the top view can also be placed below the main view. In this case, the initial insertion point corresponding to the main view should be moved down by a third distance to obtain the initial insertion point corresponding to the top view.

[0063] S504. Move the initial insertion point corresponding to the main view by a fourth distance in the opposite direction to the second direction to obtain the initial insertion point corresponding to the bottom view. This fourth distance is related to the size of the minimum bounding box of the main view and the size of the minimum bounding box of the bottom view.

[0064] In one example, the bottom view is placed below the main view. After the initial insertion point corresponding to the main view is determined, the initial insertion point corresponding to the main view is moved down by a fourth distance to obtain the initial insertion point corresponding to the bottom view. This fourth distance is determined based on the dimensions of the minimum bounding box of the main view and the minimum bounding box of the bottom view. In a specific example, this fourth distance is half the height of the minimum bounding box of the main view, plus half the height of the minimum bounding box of the bottom view, plus a fixed value, which can be preset.

[0065] In other examples, the bottom view can also be set below the main view. In this case, the initial insertion point corresponding to the main view should be moved up by the fourth distance to obtain the initial insertion point corresponding to the bottom view.

[0066] S102. Determine the offset vector corresponding to each view. The offset vector is used to characterize the relative positional relationship between the two-dimensional midpoint of the view and the two-dimensional midpoint of the target component within the view. The two-dimensional midpoint of the target component is the center of the minimum bounding box of the target component.

[0067] The purpose of this step is to determine the offset vector between the two-dimensional midpoint of the view and the two-dimensional midpoint of the component within the view. This disclosure does not limit the method of determining the offset vector; in one feasible approach, such as... Figure 6 As shown, the offset vector corresponding to each view is determined, including:

[0068] S601. Obtain the coordinates of the two-dimensional midpoint of the view.

[0069] This disclosure does not limit the specific method of obtaining the two-dimensional midpoint of the view. For example, the coordinates of the two-dimensional midpoint of each view to be inserted can be obtained separately. The two-dimensional midpoint is the center of the minimum bounding box of the view to be inserted. The minimum bounding box of the view to be inserted is the smallest bounding rectangle with the maximum x-coordinate, minimum x-coordinate, maximum y-coordinate, and minimum y-coordinate of all contents in the view as its boundary. The x-coordinate of its center is the average of the maximum x-coordinate and the minimum x-coordinate, and the y-coordinate of its center is the average of the maximum y-coordinate and the minimum y-coordinate.

[0070] However, this is not the only method. In other embodiments, obtaining the coordinates of the 2D midpoint of the view includes: obtaining the coordinates of the 3D midpoint of the target object, where the 3D midpoint is the center of the minimum bounding box of the target object in 3D space; constructing a transformation matrix based on the world coordinate system of 3D space and the view's corresponding viewing coordinate system; and obtaining the coordinates of the 2D midpoint of the view based on the transformation matrix and the coordinates of the 3D midpoint of the target object. Thus, only one minimum bounding box needs to be constructed—that is, the minimum bounding box of the target object in 3D space—to obtain the 2D midpoints of all views to be inserted, improving the efficiency of obtaining the 2D midpoints of the view.

[0071] The world coordinate system is the absolute coordinate system in the three-dimensional space where the target object is located. In this world coordinate system, every point has an absolute coordinate.

[0072] The observation coordinate system can be considered the observer's local coordinate system, a coordinate system constructed with the observer's position as the origin. It can be understood that for each view to be inserted, there is a corresponding observation coordinate system.

[0073] In one possible implementation, a transformation matrix is ​​constructed based on the world coordinate system in three-dimensional space and the observation coordinate system corresponding to the view. This includes: determining the observation coordinate system corresponding to the view, i.e., determining the observation point of the view and three basis vectors originating from the observation point; the three basis vectors include a right-view basis vector, a top-view basis vector, and a view basis vector, where the right-view basis vector is a basis vector extending to the right from the observation point, the top-view basis vector is a basis vector extending upward from the observation point, and the view basis vector is a basis vector extending away from the view from the observation point; and determining the transformation matrix based on the three basis vectors of the world coordinate system and the three basis vectors of the observation coordinate system.

[0074] In one possible implementation, obtaining the coordinates of the two-dimensional midpoint of the view based on the transformation matrix and the coordinates of the three-dimensional midpoint of the target object includes: multiplying the coordinates of the three-dimensional midpoint of the target object by the transformation matrix to obtain a new coordinate; and taking the first two digits of the new coordinate to obtain the coordinates of the two-dimensional midpoint of the view. For example, assuming the coordinates of the three-dimensional midpoint S of the target object are (x, y, z), and the transformation matrix is ​​P, multiplying the coordinates of the three-dimensional midpoint S by the transformation matrix P to obtain new coordinates (x', y', z'), and taking (x', y') from the coordinates (x', y', z') gives the coordinates of the two-dimensional midpoint of the view.

[0075] S602. Obtain the coordinates of the two-dimensional midpoint of the target component within the view.

[0076] This disclosure does not limit the specific method of obtaining the two-dimensional midpoint of the target component in the view. For example, the coordinates of the two-dimensional midpoint of each target component to be inserted into the view can be obtained separately. The two-dimensional midpoint is the center of the minimum bounding box of the target component. The minimum bounding box of the target component is the smallest bounding rectangle with the maximum x-coordinate, minimum x-coordinate, maximum y-coordinate, and minimum y-coordinate of all contents as its boundary. The x-coordinate of its center is the average of the maximum x-coordinate and the minimum x-coordinate, and the y-coordinate of its center is the average of the maximum y-coordinate and the minimum y-coordinate.

[0077] However, this is not the only method. In other embodiments, obtaining the coordinates of the two-dimensional midpoint of a target component within the view includes: obtaining the coordinates of the three-dimensional midpoint of the target component, where the three-dimensional midpoint is the center of the minimum bounding box of the target component in three-dimensional space; constructing a transformation matrix based on the world coordinate system of three-dimensional space and the viewing coordinate system corresponding to the view; and obtaining the coordinates of the two-dimensional midpoint of the target component within the view based on the transformation matrix and the coordinates of the three-dimensional midpoint of the target component. Thus, only one minimum bounding box needs to be constructed—that is, the minimum bounding box of the target component in three-dimensional space—to obtain the two-dimensional midpoints of all target components to be inserted into the view, improving the efficiency of obtaining the two-dimensional midpoints of the target components.

[0078] The method for obtaining the coordinates of the two-dimensional midpoint of the target component within the view can be found in the method for obtaining the coordinates of the two-dimensional midpoint of the view, and will not be repeated here.

[0079] S603. Subtract the coordinates of the two-dimensional midpoint of the target component within the view from the coordinates of the two-dimensional midpoint of the view to obtain the offset vector corresponding to the view.

[0080] For example, assuming the coordinates of the two-dimensional midpoint of the view are obtained as (X1, Y1) in step S501, and the coordinates of the two-dimensional midpoint of the target component within the view are obtained as (X2, Y2) in step S502, then the offset vector corresponding to this view is (X1-X2). 2, (Y1-Y2).

[0081] S103. Based on the initial insertion point and offset vector corresponding to each view, determine the target insertion point corresponding to each view in the drawing. The target insertion point is the target insertion position of the two-dimensional midpoint of the view in the drawing.

[0082] Based on the initial insertion point corresponding to each view obtained in step S101 and the offset vector corresponding to each view determined in step S102, the target insertion point corresponding to each view is obtained.

[0083] In one feasible approach, the target insertion point corresponding to each view is determined, such as... Figure 7 As shown, it includes the following steps:

[0084] S701. Determine a first ratio, which is the ratio of the scaling factor of the drawing to the scaling factor of the view.

[0085] Generally speaking, the scaling ratio of the drawing is different from that of the view. The offset vector determined in step S102 is the offset vector in the view, not the offset vector in the drawing. In order to obtain the offset vector in the drawing, it is necessary to determine the first ratio between the scaling ratio of the drawing and the scaling ratio of the view.

[0086] For example, if the scaling ratio of the drawing is 1:100 and the scaling ratio of the view is 1:25, then the first ratio is 0.25.

[0087] S702. Based on the first ratio and the offset vector corresponding to each view, obtain the actual offset vector of each view within the drawing.

[0088] Continuing with the previous example, if the offset vector corresponding to the view is (X1-X...) 2, If the first ratio is k, then the actual offset vector of the view within the drawing is k(X1-X2). 2, (Y1-Y2).

[0089] S703. Based on the initial insertion point and the actual offset vector of the view, obtain the target insertion point corresponding to the view.

[0090] Specifically, the coordinates of the initial insertion point corresponding to the view are added to the actual offset vector of the view within the drawing to obtain the coordinates of the target insertion point corresponding to the view. For example, assuming the coordinates of the initial insertion point corresponding to the view are (X0, Y0), the actual offset vector of the view is k(X1-X...). 2, Y1-Y2), and (X0,Y0) and k(X1-X 2, Adding (Y1-Y2) gives the coordinates of the target insertion point as (X0+kX1-kX). 2, (Y0+kY1-kY2).

[0091] It is understandable that when the initial insertion position of the two-dimensional midpoint of the view is (X0, Y0), the initial insertion position of the target component in the view should be {X0-(kX1-kX2), Y0-(kY1-kY2)};

[0092] When the target insertion position of the two-dimensional midpoint of the view is (X0+kX1-kX), 2, If the target insertion point is (X0, Y0), then the target insertion position of the target component in the view should be (X0, Y0). That is to say, after the view is offset within the drawing, the two-dimensional midpoint of the target component in the view is the initial insertion point of the view. According to the previous text, the initial insertion points of multiple views to be inserted are arranged along a predetermined direction. Therefore, after the offset, the two-dimensional midpoints of the target components in the multiple views to be inserted are arranged along the preset direction.

[0093] S104. Insert each view into the drawing based on the target insertion point corresponding to each view.

[0094] The two-dimensional midpoints of the target components in each view inserted in the drawing are arranged along a preset direction, that is, the two-dimensional midpoints of the target components in each view are aligned along a preset direction. Visually, the target components in each view are aligned along the preset direction, which makes the drawing more aesthetically pleasing and easier for technicians to read during processing.

[0095] Following the previous example, assuming the preset directions are the first and second perpendicular directions, and the views to be inserted are the left view, front view, right view, top view, and bottom view. Based on the target insertion points corresponding to each view, insert the left view, front view, right view, top view, and bottom view into the drawing, as follows. Figure 8 As shown, the top and bottom edges of the target component in the left, front, and right views are aligned along the first direction, while the left and right edges of the target component in the top, front, and bottom views are aligned along the second direction. At this time, the viewports of each view are no longer aligned.
