Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of architectural design, and particularly relates to a layout method and device of two-dimensional cutting components in a special-shaped plane. BACKGROUND

[0002] Parametric design is a design method for efficiently completing architectural design by defining variables and their logical relationship with design results. It takes algorithmic thinking as the core and deeply binds design parameters and design results. In the design process, designers only need to change part of the parameters to update the entire design results.

[0003] The layout plane of two-dimensional cutting components has the characteristics of diversification and freedom. In the laying process of the layout plane, except for the reserved openings, the remaining areas need to be "fully paved" with component units to ensure that there is no blank area. The component units should be connected according to the specified laying method and keep the joint thickness uniform and smooth. In order to meet the "full paving" requirement of the special-shaped area, the component units should be cut into any shape, but in the laying process, the complete two-dimensional cutting components should be used first, and the two-dimensional cutting components are cut only in the boundary area of the layout plane.

[0004] Based on this, the prior art mainly has the following problems in the layout of two-dimensional cutting components: first, in the prior art, the component positioning is relatively regular and controllable when dealing with non-special-shaped plane layout, but it is difficult to achieve accurate positioning of the component units when facing special-shaped planes with complex curved surfaces or irregular geometric shapes; second, in non-special-shaped plane layout, because the boundary of the layout plane is simple, the components can easily cover the entire plane, but in the complex curved boundary characteristics of the special-shaped plane, it is difficult for the component units to cover the entire plane, and it is easy to produce uncovered blanks or gaps; third, in non-special-shaped plane layout, because the layout boundary is regular and simple, the components are mostly standard shapes, but in special-shaped plane layout, in order to fit the complex curved boundary, a large number of irregular cutting components will be generated in the edge area of the plane, and there is a lack of a method for quickly generating irregular cutting components.

[0005] Therefore, it is necessary to provide a layout method of two-dimensional cutting components in a special-shaped plane, which can quickly generate irregular cutting components in the special-shaped plane to solve the problem of difficulty in generating irregular cutting components in the special-shaped plane layout.

[0030] The two-dimensional cutting component data is the data of a complete component unit used for laying the layout plane, and the complete component unit is preferentially used for laying the layout irregular plane.

[0031] S102: creating a component plane model based on the layout plane data and the two-dimensional cutting component data.

[0032] In a possible embodiment, creating a component plane model based on the layout plane data and the two-dimensional cutting component data includes: obtaining the layout plane data, and creating a geometric entity according to the outer contour line of the plane to be laid out; and setting the thickness and material of the geometric entity to the thickness and material of the two-dimensional cutting component to obtain the component plane model.

[0033] S103: calculating the geometric size of the segmentation unit according to the two-dimensional cutting component data and the joint data.

[0034] In a specific embodiment, calculating the geometric size of the segmentation unit according to the two-dimensional cutting component data and the joint data includes: calculating the length of the segmentation unit as the sum of the length of the two-dimensional cutting component and the joint thickness; and calculating the width of the segmentation unit as the sum of the width of the two-dimensional cutting component and the joint thickness.

[0035] S104: creating a segmentation line based on the component plane model, the geometric size of the segmentation unit and the laying constraints, and obtaining a set of orthogonal segmentation lines located in the irregular plane according to the component plane model and the segmentation line.

[0036] In a possible embodiment, the extreme values of the outer contour line of the plane to be laid out in the X-axis direction and the Y-axis direction are obtained, and then a minimum value coordinate point (x min , y min ) composed of the minimum value of the X-axis direction and the minimum value of the Y-axis direction and a maximum value coordinate point (x max , y max ) composed of the maximum value of the X-axis direction and the maximum value of the Y-axis direction are formed, and an envelope rectangle capable of enveloping the entire plane to be laid out is generated based on the minimum value coordinate point and the maximum value coordinate point.

[0037] ​​In one possible embodiment, the segmentation lines are created based on a component plane model, geometric dimensions of a segmentation unit and laying constraints, and a set of orthogonal segmentation lines in a special plane is obtained according to the component plane model and the segmentation lines, including: obtaining layout plane data to determine the maximum value of an outer contour line on a coordinate axis according to the outer contour line of a plane to be laid and global coordinates, and generating an envelope rectangle enveloping the plane to be laid; obtaining a laying starting point from the laying constraints, extending a transverse segmentation line along a set laying direction with the laying starting point as a center, obtaining the width of the segmentation unit as the spacing between the segmentation lines, creating segmentation lines parallel to the transverse segmentation lines until the segmentation lines fill the envelope rectangle to obtain a set of transverse segmentation lines; creating a set of vertical segmentation lines according to a set laying mode, and the set of transverse segmentation lines and the set of vertical segmentation lines form a set of segmentation lines; judging whether the segmentation lines in the set of segmentation lines are located in the plane to be laid according to the component plane model and the set of segmentation lines, and retaining the segmentation lines when the segmentation lines are located in the plane to be laid, and the retained segmentation lines form a set of orthogonal segmentation lines.

[0038] In one specific embodiment, referring to the drawings Figure 4 , creating a set of vertical segmentation lines according to a set laying mode includes: when the set laying mode is a continuous straight laying type, creating segmentation lines perpendicular to the segmentation lines in the set of transverse segmentation lines with the laying starting point as a center to form the set of vertical segmentation lines; when the set laying mode is a staggered straight laying type, creating odd-numbered row vertical segmentation lines perpendicular to the segmentation lines in the set of transverse segmentation lines with the laying starting point as a center and obtaining the width of the segmentation unit as the length of the segmentation lines, translating the position line of the odd-numbered row vertical segmentation lines along the laying direction by the length of the segmentation unit, and translating the odd-numbered row vertical segmentation lines along a direction perpendicular to the laying direction by the width of the segmentation unit to obtain even-numbered row vertical segmentation lines, and the odd-numbered row vertical segmentation lines and the even-numbered row vertical segmentation lines form the set of vertical segmentation lines.

[0039] When the laying mode is the continuous straight laying type, the spacing between the vertical segmentation lines is the width of the segmentation unit. When the laying mode is the staggered straight laying type, the spacing between the odd-numbered row vertical segmentation lines and the spacing between the even-numbered row vertical segmentation lines are both the length of the segmentation unit, and the spacing between the nearest two segmentation lines belonging to two rows of adjacent odd-numbered and even-numbered rows is the length of the segmentation unit, and such setting can achieve the engineering requirement of “staggered joint”.

[0040] ​​In a specific embodiment, the process involves determining whether a dividing line in the dividing line set is located within the plane to be laid out, based on the component plane model and the dividing line set. If the dividing line is located within the plane to be laid out, it is retained. This includes: obtaining the coordinates of all vertices of the component plane model; selecting any point P on the horizontal dividing line, extending a ray to the left and right from point P, calculating the number F of intersections between this ray and the component plane model; when F=0, the dividing line is deleted because it is outside the plane to be laid out; when F is odd, deleting the intersections of the ray with the vertices of the component plane model and obtaining the X coordinates of the remaining intersections; when F is even, obtaining the X coordinates of all intersections of the ray with the component plane model, arranging the obtained X coordinates from smallest to largest, matching the intersections pairwise to form a set of line segments, determining whether the line segment set coincides with the dividing lines in the dividing line set, and retaining the coinciding dividing lines; selecting any point on the vertical dividing line... , with point Starting from a point, extend a ray upwards and downwards to obtain a ray. Calculate the number of intersection points between this ray and the planar model of the component. ,when =0 indicates that the dividing line is deleted outside the plane to be laid out. When the number is odd, delete the intersection points where the ray coincides with the vertex of the component's planar model and obtain the Y coordinates of the remaining intersection points. When the number is even, obtain the Y coordinates of all intersection points between the ray and the planar model of the component. Arrange the obtained Y coordinates from smallest to largest and then match the intersection points pairwise to form a set of line segments. Determine whether the set of line segments coincides with the dividing lines in the set of dividing lines, and retain the coinciding dividing lines.

[0041] For example, select any point P on a horizontal dividing line, and extend a ray to the left and right from point P to obtain a ray. Calculate the number F of intersections between this ray and the component's planar model. When F=0, it means the dividing line is deleted outside the layout plane. When F is odd, delete the intersections of the ray with the vertices of the component's planar model and obtain the X coordinates of the remaining intersections. When F is even, obtain the X coordinates of all intersections of the ray with the component's planar model. Arrange all the obtained X coordinates in ascending order into a set (x1, ..., x...). n ), where x1 < ... < x n Connect each intersection point in the set to form a straight line segment, i.e., connect x1 and x2, x3 and x4, and so on. Determine the overlap between the straight line segments formed by connecting the intersection points and the dividing lines in the set of dividing lines, and retain the overlapping dividing lines. Perform the above judgment process on all horizontal dividing lines in turn to obtain the set of retained horizontal dividing lines.

[0042] Select any point on the vertical dividing line , with point A ray is obtained by extending upward and downward from the starting point, and the number of intersection points of the ray and the component plane model is calculated When =0, the split line is deleted outside the layout plane, and when is odd, the intersection point of the ray and the component plane model vertex is deleted, and the Y coordinates of the remaining intersection points are obtained, and when is even, the Y coordinates of all intersection points of the ray and the component plane model are obtained. All the obtained Y coordinates are arranged in ascending order to form a set (y1, …, y n ), wherein y1<…<y n , and the intersection points in the set are connected two by two to form straight line segments, i.e. y1 and y2 are connected, y3 and y4 are connected, and so on. The overlapping part of the straight line segment formed by connecting the intersection points and the split line set is judged, and the overlapping split line is retained. The above judgment process is performed on all vertical split lines in turn to obtain the retained vertical split line set.

[0043] The retained horizontal split line set and the retained vertical split line set form an orthogonal split line set.

[0044] S105: According to the orthogonal split line set, the component plane model is segmented to obtain the component unit, and the model seam is obtained by instantiating the orthogonal split line according to the seam data, and the cutting layout model is completed.

[0045] According to the orthogonal split line set, the component plane model is segmented to obtain the component unit, and the model seam is obtained by instantiating the orthogonal split line according to the seam data, and the cutting layout model is completed, including: obtaining the component plane model and the orthogonal split line set; based on the orthogonal split line set, the component plane model is segmented to obtain the component unit; according to the seam data, the gap distance of the two-dimensional cutting component is set to the seam thickness, and the orthogonal split line is instantiated according to the seam thickness to obtain the seam, and the seam and the component unit form the cutting layout model.

[0046] In a possible embodiment, after obtaining the cutting layout model, further comprising: calculating the area of each component unit according to the cutting layout model, and calculating the total area of all component units; and establishing a component area information detail table according to the area of each component unit and the total area of all component units. The component area information detail table can be used as accurate material consumption reference data, and can provide reference for actual engineering material procurement and planning.

The layout of the two-dimensional cutting component by the orthogonal cutting method proposed by the application can not only process a complex special layout plane, but also meet the demand of preferentially using a complete component unit in the layout process. The layout of the two-dimensional cutting component in the special plane mainly using the complete two-dimensional cutting component and supplemented by the special component unit can be quickly and accurately obtained, the irregular component required by the edge of the special plane is generated, and the effect of saving raw materials and improving the design efficiency and construction accuracy is achieved.
