Description

Technical Field

[0001] The present invention relates to the field of architectural design, and in particular to a building enclosure component design method and electronic equipment. Background Art

[0002] During the architectural design process, architects use Computer Aided Design (CAD) software to design building envelope components, such as doors, windows, curtain walls, and railings.

[0003] In traditional 2D CAD, such as AutoCAD, architects use lines to draw the horizontal and vertical projections of doors and windows in the floor plan and door and window detail drawings respectively. This drawing method is cumbersome, non-intuitive, and difficult to modify and adjust. In traditional 3D CAD, such as Revit, each window grid type needs to be defined in advance. However, there are a large number of doors and windows in a project, and there are many different types of grids, such as Figure 1 The various window types shown vary in their grid layouts and frame materials. In Revit, each window type must be defined and created as a family. Instances are then placed during the actual design process. Therefore, traditional 3D CAD-based design methods are cumbersome and inefficient. Summary of the Invention

[0079] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0080] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0081] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0082] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0083] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0084] See also Figure 2 , is a flowchart of the building enclosure design method provided by an embodiment of the present invention. It should be understood that the operations of the flowchart can be implemented in a non-sequential order, and steps that have no logical contextual relationship can be reversed or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flowchart, or remove one or more operations from the flowchart, under the guidance of the content of the present invention. Figure 2 As shown, the method includes the following steps:

[0085] S1. Draw a plan sketch of the building envelope components.

[0086] S2, construct the control surface based on the plane sketch and the obtained size parameters.

[0087] S3, based on the control surface, the configured frame information and the panel information, a solid model of the building envelope is established.

[0088] In this embodiment, the design and drawing of building enclosure components can be realized by using design software in electronic equipment. The electronic equipment can be a computer device, a server or other equipment with data and image processing functions. Building enclosure components can be structures such as doors, windows, curtain walls, and railings. The following is a detailed description using windows as an example. The final production of windows (doors, curtain walls, railings, etc.) is assembled from frames, panels and some hardware parts. If the frame is abstracted as an edge and the panel is abstracted as a surface, it is actually a mathematical graph, which can eventually be abstracted as follows Figure 3 The diagram with the relevant topology shown in .

[0089] Based on the above research findings, in this embodiment, the design of the building envelope is converted into a design of a graph with a related topological structure.

[0090] First, a plan sketch of the building envelope can be drawn, such as Figure 4 As shown in the figure, the plane sketch contains a baseline, which can be used as the basis for surface construction. In addition, the size parameters can be obtained based on the architect's settings, including height parameters, width parameters, etc. The size parameters can be set in the parameter interface. The set size parameters can be intuitively expressed in the plane sketch (such as Figure 4 C1812, LSM1222, etc.). Control surfaces can be created based on plane sketches and size parameters, such as Figure 5 As shown, the control surface is a solid surface of the building envelope component, that is, a surface in the model space.

[0091] In addition, the architect can also configure frame information and panel information, where the frame information may include frame type, cross-section profile, frame material, etc., and the panel information may include panel type, panel material, panel thickness, etc.

[0092] Based on the above, on the basis of the control surface, based on the configured frame information and panel information, the solid model of the building enclosure component can be constructed. The obtained solid model can be Figure 6 As shown in .

[0093] The building envelope component design method provided in this embodiment abstracts the building envelope components into a graph topology structure composed of faces, edges, etc., and combines size parameters, frame information and panel information to efficiently realize the design of building envelope components with wide adaptability.

[0094] See also Figure 7 In this embodiment, the step of establishing a solid model based on the control surface, the configured frame information, and the panel information can be implemented in the following manner:

[0095] S31: Divide the control surface into multiple sub-surfaces, and perform open sector setting for one or more of the multiple sub-surfaces.

[0096] S32: Based on the multiple sub-surfaces, opening sashes, and configured frame information and panel information, a solid model of the building enclosure component is established.

[0097] On the control surface, architects can divide it into multiple sub-surfaces based on their needs. Each sub-area with an independent outline is a sub-surface.

[0098] In addition, it should be noted that due to the structure of certain types of windows, such as corner windows and bay windows, their control surfaces are themselves a combination of multiple surfaces. Therefore, the control surface itself contains multiple sub-surfaces, for example, Figure 8In the window shown in FIG, the parallel surfaces on both sides and the front surface can be understood as sub-surfaces. Therefore, in this embodiment, the obtained sub-surfaces may include those obtained by the architect by dividing the control surface, and may also include sub-surfaces inherent in the established control surface.

[0099] After dividing each sub-surface, the architect can design the opening sash, and can specify one or more sub-surfaces to be opened. For example, some windows may have only one opening sash, while others may have two. It should be understood that some windows may not have an opening sash.

[0100] After dividing the sub-surface and setting the open fan, the structure diagram is as follows: Figure 9 As shown in .

[0101] See also Figure 10 In this embodiment, the step of dividing the control plane into multiple sub-planes can be implemented in the following manner:

[0102] S311: Duplicate the control plane to obtain an initial control plane and a divided control plane.

[0103] S312: Divide the control plane into multiple sub-planes.

[0104] S313: Obtain surface parameters of each sub-surface.

[0105] In this embodiment, a single control plane is initially established. This control plane can be duplicated to create two control planes, named the original control plane (Original Body) and the split control plane (Split Body). Subsequent operations can be performed on the split control plane, while the original control plane can be saved for future use. Therefore, the control planes mentioned later specifically refer to the split control plane.

[0106] Building enclosure components generally have internal and external directions. Especially when opening sashes are required, it is necessary to clearly indicate which side the sashes open to. In order to clearly indicate the internal and external directions, the two sides of the control surface can be marked to indicate whether it is the side facing inward or the side facing outward. Optionally, the two sides can be marked with different colors, for example Figure 11 and Figure 12 As shown in , the gray side represents the inner side, and the white side represents the outer side. Alternatively, different marks can be used to mark the two surfaces respectively. The marks can be words, letters, symbols, etc., as long as they can indicate the directions of the two surfaces.

[0107] Based on the above-mentioned initial control surface and divided control surface, the divided control surface is divided into multiple sub-surfaces, and each sub-surface has its own surface parameters. The surface parameters are saved for use in subsequent design of each sub-surface.

[0108] In this embodiment, when dividing the control surface into multiple sub-surfaces, a variety of different methods can be used for division. Figure 13 In one possible implementation, this can be achieved by:

[0109] S3121A, determine the projection point of the cursor on the divided control surface.

[0110] S3122A, construct a partitioning surface perpendicular to the partitioning control surface based on the projection point.

[0111] S3123A, obtaining an intersection line between the partitioning surface and the partitioning control surface, and partitioning the partitioning control surface based on the intersection line to obtain a plurality of sub-surfaces.

[0112] In this embodiment, based on the architect's operation, the position of the cursor on the divided control surface can be captured, specifically, the position on a certain sub-surface of the divided control surface.

[0113] Based on the captured cursor, you can determine the cursor's projection point on the division control surface. A division surface perpendicular to the division control surface is constructed through this projection point. The constructed division surface is infinite and can be vertical (with its normal perpendicular to the Z axis of the model space coordinate system) or horizontal (with its normal parallel to the Z axis of the model space coordinate system).

[0114] When the dividing surface is a vertical surface, such as Figure 14 As shown in , the division surface intersects with the division control surface to obtain an intersection line, and the intersection line can divide the division control surface.

[0115] During actual operation, before clicking OK, you can move the cursor to display a preview of the division effect. In addition, you can draw control dimension lines from the cursor position to the left and right edges of the division control surface to facilitate positioning.

[0116] When the dividing surface is a horizontal surface, such as Figure 15 As shown in , similarly, the division surface intersects with the division control surface to obtain an intersection line, and the division control surface is divided based on the intersection line.

[0117] During operation, before clicking OK, you can preview the division by moving the cursor. You can also draw control dimension lines from the cursor position to the upper and lower edges of the division control surface to facilitate positioning.

[0118] In addition to the above-mentioned method of dividing the control surface based on vertical and horizontal planes, the line division method can also be used. Figure 16 In another possible implementation, the step of dividing the control surface into multiple sub-surfaces may be implemented as follows:

[0119] S3121B: Determine two endpoints on the divided control plane based on the operation information.

[0120] S3122B, construct a straight line passing through the two endpoints, and obtain two intersection points of the straight line and the contour dividing the control surface.

[0121] S3123B: Divide the control surface based on the line segment between the two intersection points to obtain multiple sub-surfaces.

[0122] In this embodiment, operation information can be obtained based on the architect's operation, and the operation information can indicate the two endpoints on the divided control surface specified by the architect. The two endpoints may be located on the contour of the divided control surface, such as Figure 17 As shown in , they may also be located inside the divided control plane, such as Figure 18 As shown in .

[0123] Therefore, to ensure that the control surface can be partitioned based on two ports, a straight line passing through the two endpoints can be constructed, and this straight line has two intersection points with the outline of the partitioned control surface. If the two endpoints are set on the outline of the partitioned control surface, the two intersection points are the two endpoints. If the two endpoints are set inside the partitioned control surface, the two intersection points are the intersection points of the extended line connecting the two endpoints and the outline of the partitioned control surface.

[0124] The partitioning control surface can be divided based on the line segment between the two intersection points. For example, the partitioning control surface can be divided into two sub-surfaces.

[0125] In this embodiment, the intersection lines, line segments, etc. used to divide the control surface are collectively referred to as dividing lines. Dividing lines can be constructed, modified, deleted, etc. After a sub-surface is obtained by dividing the sub-surface using a dividing line, the dividing line can be added to the sub-surface topology, deleting the original sub-surface topology, and reconstructing the topology including the newly divided sub-surface.

[0126] When you need to delete a dividing line, the sub-surfaces originally divided by the dividing line are merged again. It should be noted that only the dividing line can be deleted, and the original edge line, such as the outline of the original dividing control surface, cannot be deleted.

[0127] The above-mentioned saved original control surface has the original edge information. Therefore, the original control surface can be used as a reference to ensure that the original edge is not deleted by performing a matching check with the edge of the original control surface.

[0128] After dividing into multiple sub-surfaces based on any of the above methods, the surface parameters of each sub-surface can be obtained, so that the surface parameters can be extracted and related settings can be made later. Figure 19In this embodiment, the step of obtaining the surface parameters of each sub-surface can be achieved by:

[0129] S3131: For each edge of each sub-face, construct two half-edges in opposite directions.

[0130] S3132, starting from any half-edge, search for the next half-edge in directional order until the loop returns to any half-edge, determine that all half-edges on the loop constitute a sub-face, and obtain parameter information of all half-edges on the loop to obtain the surface parameters of the sub-face.

[0131] In this embodiment, a "half-edge data structure" is introduced to determine each sub-surface and obtain the surface parameters of the sub-surface. Figure 20 The partition control surface shown on the left contains multiple sub-surfaces. For example, for the edge e1 of the sub-surface, the following can be constructed: Figure 20 The two half-edges in opposite directions are shown on the right, e10 and e11. Each other edge in the partition control surface can be constructed into two half-edges in opposite directions in this way.

[0132] Since the constructed half-edges have a direction, each half-edge can record the half-edges connected to it, which can be recorded as the preceding half-edge and the following half-edge respectively. Each time a new edge is inserted, the local half-edge data can be reconstructed.

[0133] Based on the preceding and succeeding half-edges recorded for each half-edge, starting from any half-edge, the search for the next half-edge is performed in directional order. When the loop eventually returns to itself, the half-edges in the loop form a closed loop, and the area enclosed by this loop is a sub-face. Thus, a face records the parameter information of all edges on the contour. Similarly, each edge is decomposed into two half-edges, and each half-edge's contribution to a face is recorded on the edge. Therefore, edges also record face parameter information; edges may have faces on both sides or only on one side. Each face records the numbers of the edges it encloses, and each edge records the numbers of the faces it contributes to. This controls the topological structure of the face. For example, starting from half-edge e11 and searching for the succeeding half-edges in directional order, a loop consisting of e11-e21-e31-e41-e11 is obtained. The geometric line segments represented by e11, e21, e31, and e41 in this loop are linked to form a closed contour, which constitutes a sub-face f1.

[0134] Based on the above, the architect can set the opening fan, which is located in the area of ​​one or more sub-surfaces among multiple sub-surfaces. By assigning opening information to the sub-surface, the opening fan is set. If the sub-surface does not have an opening fan and no opening symbol, the sub-surface will be Figure 21 As shown in the first figure. The opening methods of the opening sash include flat opening, push-pull and flat push (respectively as shown in Figure 21 As shown in the second to fourth figures), you can also set the opening symbol (indicating that this sub-surface does not have a panel, such as Figure 21 (as shown in the fifth figure).

[0135] It should be understood that the graphic expressions of all symbols can be adjusted based on needs and are not limited thereto.

[0136] like Figure 21 The second image shows a casement opening method. This refers to a door opening with one side as the axis, either inward or outward. Therefore, when setting up the casement opening method, you need to specify which side is the axis of opening and determine whether it opens inward or outward.

[0137] When setting the casement opening mode, the architect can place the cursor on a sub-surface, and the sub-surface will be divided into 4 areas, such as Figure 22 As shown in the figure, there are four areas: top, bottom, left, and right. The area where the cursor falls indicates that the corresponding edge of the area is set as the open axis. Figure 23 As shown, the left side, top side, right side and bottom side of the sub-surface are used as the opening axis respectively.

[0138] The area division method may be to draw angle bisectors from each corner point, and divide the sub-surface into four areas by the angle bisectors.

[0139] like Figure 21 The push-pull opening method shown in the third figure requires specifying a sub-face and giving a push-pull direction. The push-pull direction is the up, down, left, and right directions of the sub-face tangent direction.

[0140] like Figure 21 The push-to-open method, shown in the fourth figure, requires only one sub-surface (generally pushing outward). This method is primarily used on curtain walls.

[0141] A door, window, curtain wall, or balustrade of the same type is composed of edges and faces. However, due to differences in type and style, the specific edges and faces corresponding to the frames and panels may differ. To facilitate standardized management, in this embodiment, the style information of the frames and panels is pre-set.

[0142] like Figure 24 As shown in , all doors, windows, curtain walls, and railings as a whole may include several frames (edges) and several panels (surfaces).

[0143] Among them, Figure 25 As shown in , the middle frame of the flat hinged door includes an outer frame (door cover) and the panel is a door panel.

[0144] like Figure 26As shown in , the middle frame of the aluminum frame glass door includes an outer main frame and an opening sash frame, and the panel is a glass panel.

[0145] like Figure 27 As shown in , the frame of the bay window includes an outer main frame, a corner frame, an inner horizontal frame, an inner vertical frame and an opening sash frame, and the panel is a glass panel.

[0146] like Figure 28 As shown in , the glass curtain wall's central frame includes an outer horizontal frame, outer vertical frames, corner frames, inner horizontal frames, inner vertical frames, and sash frames. The outer horizontal frame includes an outer horizontal inner frame and an outer horizontal outer frame. The outer vertical frames include an outer vertical inner frame and an outer vertical outer frame. The corner frames include an inner corner frame and an outer corner frame. The inner horizontal frame includes an inner horizontal inner frame and an inner horizontal outer frame. The inner vertical frames include an inner vertical inner frame and an inner vertical outer frame. Furthermore, panels include glass panels, louver panels, and the like.

[0147] Taking the above example, you can configure frames and panels for various types of doors, windows, curtain walls and balustrades to form a style. For example, Figure 29 In the bay window shown in the figure, the frames represented by the edges include the outer frame, corner frame, inner horizontal frame, inner vertical frame, opening sash frame, etc., and the panels represented by the faces are generally glass panels.

[0148] It should be noted that if Figure 30 As shown in the figure, inner and outer frames may appear on the same side of the curtain wall.

[0149] On this basis, the material, geometric characteristics and other information of the frame and panel can be set on the parameter setting interface. A rough rectangle can be specified in the design stage, and in the in-depth design and production stage, it can be set according to the actual production model specifications to establish the solid models required at each stage.

[0150] Based on the above settings, in this embodiment, when configuring the framework information and panel information, it can be achieved in the following ways:

[0151] Based on the initial control surface and the topological structure of the divided control surface, the edges corresponding to each type of frame are determined. Based on the operation information and the pre-set panel style information, the panel information of each sub-surface of the control surface is determined.

[0152] In this embodiment, for building enclosure components in a certain project, it is necessary to classify the edges on the control surface, and different frameworks are applied to different types of edges.

[0153] The initial control surface determines the edges corresponding to the outer border and corner boxes. In the initial control surface, edges with only one adjacent face are always located on the outer boundary, so these edges correspond to the outer border. If the initial control surface contains multiple sub-faces, corner boxes will also appear. If an edge in the initial control surface has two adjacent faces that are not coplanar, then this edge corresponds to a corner box. In the partitioning control surface, edges that do not overlap with edges in the initial control surface, that is, internal partitioning lines, can be classified as inner borders.

[0154] The opening sash frame is a surface provided with an opening, and the multiple edges included in its outline are the opening sash frame. It should be understood that the edges of the opening sash frame are also outer frames, corner frames or inner frames.

[0155] In addition, it's often necessary to distinguish between vertical and horizontal frames for both outer and inner borders. Generally, this can be done by calculating the angle between the edge and the Z-axis of the model space coordinate system. If the angle is less than a set threshold, it's considered a vertical frame; if the angle is greater than or equal to the set threshold, it's considered a horizontal frame. This threshold, for example, can be 45 degrees, and can be set based on actual business needs.

[0156] After completing the determination of each sub-surface, opening fan, frame information and panel information through the above methods, you can build a solid model of the building envelope based on this information. Figure 31 In this embodiment, this step can be implemented in the following ways:

[0157] S321 , obtaining frame information of a configured frame corresponding to each edge in the control surface, and obtaining a frame cross section of the frame.

[0158] S322, using each edge as a path, performing lofting based on the frame cross section to obtain a corresponding lofted entity.

[0159] S323, assigning a texture corresponding to the frame to the lofted entity to obtain a frame entity.

[0160] S324: stretching the control surface based on the panel thickness in the configured panel information to obtain a stretched entity, assigning a corresponding panel material to the stretched entity to obtain a panel entity.

[0161] S325, obtaining a solid model of the building envelope component based on the frame entity and the panel entity.

[0162] In this embodiment, when each edge is used as a path and the frame cross section is used for lofting, the above can be achieved by the following methods:

[0163] The corresponding eccentricity value is determined according to the type of the frame section, and the positional relationship between the frame section and the path when each edge is used as a path is determined based on the eccentricity value; based on the positional relationship, the frame section is lofted with each edge as a path.

[0164] The eccentricity value refers to the distance between the center point and the edge of the frame section. Figure 32 As shown in the , the outer frame section will deviate inwards from the control surface, not outwards. The inner frame section is centered, meaning the intersection of the edges on the inner frame section coincides with the inner section center. To open the fan frame section, you need to set it inwards based on the inner or outer frame section.

[0165] When lofting the frame section and forming a solid model, the solid model of the panel can be calculated based on the panel information settings after deducting the edges occupied by the frames on each side.

[0166] In this embodiment, considering that after the frame cross-section is lofted to form a frame, the frame edges may overlap at corners and intersections, after forming the frame, the priority of each of the two intersecting frames can be obtained, and the style of the intersection of the two frames can be set based on the priority of each frame.

[0167] The priority of two intersecting frames can be set based on the requirements. For example, if the priorities of the two frames are the same, the style of the intersection position is as follows: Figure 33 As shown in the first figure. If the vertical frame has a higher priority than the horizontal frame, the style of the intersection position will be as follows Figure 33 As shown in the second figure. If the horizontal frame has a higher priority than the vertical frame, the style of the intersection position will be as follows Figure 33 As shown in the third figure.

[0168] During implementation, the edge occupied by each face frame can be deducted according to the priority of each frame, and the solid model of the panel can be calculated based on the panel setting information.

[0169] After completing the construction of the solid model of the frame and the solid model of the panel, the final solid model of the building envelope is obtained, such as Figure 34 shown.
