[0047] In some embodiments, before determining the range of generating the special-shaped hole in the BIM model, the method further comprises:

[0048] In the BIM model, the special-shaped hole is generated.

[0049] In some embodiments, in the BIM model, the special-shaped hole can be generated by the following steps:

[0050] In step S302, in the BIM model, the size parameters of each through-wall part in the through-wall part combination are obtained.

[0051] The through-wall part includes: air pipe, water pipe and bridge. Specifically, there can be various combination implementation modes. For example, it can be a combination of air pipes, a combination of water pipes, a combination of bridges, or a combination of air pipes and water pipes, thereby generating the demand for a special-shaped hole.

[0052] In step S304, a transition rectangle and a transition rectangle assembly are generated according to the size parameters of each through-wall part and a predetermined expansion value and a tolerance value.

[0053] Referring to FIG. 3, the transition rectangle assembly is generated according to the size parameters of each through-wall part and the predetermined expansion value and the tolerance value. Figure 5 Each through-wall part is expanded to generate a first transition rectangle according to the predetermined expansion value, and is expanded to generate a second transition rectangle according to the tolerance value.

[0054] In the embodiment, for the air pipe and the bridge, the hole expansion reference is: the air pipe: the width and the height are expanded. The bridge: the width and the height are expanded. For the water pipe, the size expansion is performed according to the following table 1.

[0055] Diameter Opening size when water pipe has no insulation (insulation thickness is 0) Opening size when water pipe has insulation (insulation thickness is greater than 0) 50 170x170 200x200 65 200x200 250x250 80 200x200 250x250 100 200x200 300x300 125 250x250 300x300 150 300x300 400x400 200 350x350 400x400 250 450x450 550x550 300 500x500 550x550 350 550x550 600x600 350 or more (D+200) x (D+200) (D+250) x (D+250)

[0056] Table 1

[0057] The expansion default value: water pipe 50, bridge 50, air pipe 50, unit: millimeter. It can also be flexibly set according to the needs.

[0058] In step S306, the type of the special-shaped hole to which the through-wall part combination belongs is determined according to each transition rectangle.

[0059] In the embodiment, referring to FIG. 3, the type of the special-shaped hole to which the through-wall part combination belongs is determined according to each transition rectangle. Figure 4A plurality of special-shaped hole types can be preset. The special-shaped hole types include five types.

[0060] The first type is an L shape rotated 90 degrees counterclockwise, the second type is a T shape, the third type has a straight top surface and a left side longer than a right side, which can be regarded as a shape obtained by removing a deformed L shape from a lower right corner of a rectangle, and the L deformation is that the L is rotated 90 degrees counterclockwise and then flipped about a vertical axis.

[0061] The fourth type has a straight top end and a jagged bottom edge, which can be regarded as a part remaining after removing a deformed L shape from a lower right corner of a rectangle, and the L deformation is that the L is rotated clockwise.

[0062] The fifth type is a rectangle.

[0063] In step S308, the profile of the transition rectangle assembly is adjusted according to the special-shaped hole type, so that the profile of the transition rectangle assembly is adjusted to the profile of the special-shaped hole of the type.

[0064] In this embodiment, the profile of the transition rectangle assembly can be adjusted to the profile of the special-shaped hole of the type. In this way, in the BIM three-dimensional model of the wall, the types of the holes are within the range of the preset types, which is conducive to the standardization and uniformity of the holes, improves the efficiency of the holes, improves the management efficiency of the holes, and further helps to improve the construction efficiency of the holes.

[0065] In step S310, the special-shaped hole is generated on the wall according to the profile of the special-shaped hole.

[0066] The above technical solutions of the present application obtain the size parameters of each wall-penetrating part in the wall-penetrating part combination in the BIM model, generate a transition rectangle according to a predetermined expansion value and a tolerance value, and then determine the special-shaped hole type to which the wall-penetrating part combination belongs, adjust the profile of the transition rectangle assembly according to the special-shaped hole type, so that the profile of the transition rectangle assembly is adjusted to the profile of the special-shaped hole of the type, and generate the special-shaped hole on the wall. In this way, it is conducive to the standardization and uniformity of the holes, improves the efficiency of the holes, improves the management efficiency of the holes, and further helps to improve the construction efficiency of the holes.

[0067] In an embodiment, referring to FIG. 1, the wall-penetrating part combination includes a plurality of wall-penetrating parts, and each wall-penetrating part has a corresponding transition rectangle. Figure 6 In step S306, determining the special-shaped hole type to which the wall-penetrating part combination belongs according to each transition rectangle can further include the following steps:

[0068] Determine the bottom edge of each transition rectangle.

[0069] Determine the two sides of the transition rectangle aggregate;

[0070] Determine the number of bases, and a first base with the smallest ordinate and a second base with the second smallest ordinate;

[0071] determining a vertical distance between the second bottom edge and the first bottom edge;

[0072] Determine a first distance from the left endpoint of the first bottom edge to the left side and a second distance from the right endpoint to the right side respectively;

[0073] respectively determining a first adjacent horizontal distance between one end of the second bottom side and an adjacent end of the first bottom side, and a second adjacent horizontal distance between the other end of the second bottom side and an adjacent side side;

[0074] Determine whether the number of first base edges is 1. If the number of first base edges is 1, perform the following steps:

[0075] determining whether the first distance and the second distance are greater than or equal to a predetermined reference threshold, and determining that the corresponding irregular-shaped hole type is the second type if the first distance and the second distance are greater than or equal to the predetermined reference threshold;

[0076] If the first distance and the second distance are less than the reference threshold, determining that the corresponding irregular-shaped hole type is the fifth type;

[0077] If the first distance is greater than or equal to the reference threshold and the second distance is less than the reference threshold, the corresponding type is determined to be the first, third, or fourth type.

[0078] In one embodiment, in response to the first distance being greater than or equal to the reference threshold and the second distance being less than the reference threshold, the corresponding type is determined to be the first, third, or fourth type, and then the following steps may be further performed:

[0079] In step S401, it is determined whether the first adjacent horizontal distance is less than the reference threshold. If the first adjacent horizontal distance is less than the reference threshold, step S402 is executed; otherwise, step S403 is executed.

[0080] In step S402, it is determined whether the second adjacent horizontal distance is less than the reference threshold. If the second adjacent horizontal distance is less than the reference threshold, the type is determined to be the first type.

[0081] In this embodiment, the reference threshold can be set flexibly. Figure 2 In the first type shown, the first adjacent horizontal distance and the second adjacent horizontal distance are both zero.

[0082] If the second adjacent horizontal distance is greater than or equal to the reference threshold, the type is determined as the fourth type.

[0083] In the present embodiment, refer to the fourth type schematic diagram in FIG. 4, the first adjacent horizontal distance is 0, and the second adjacent horizontal distance L2 is greater than 0, which meets the determination condition. Figure 4

[0084] In step S403, it is determined whether the second adjacent horizontal distance is less than the reference threshold; if yes, the type is determined as the third type, and if no, step S404 is performed.

[0085] In the present embodiment, refer to the third type schematic diagram in FIG. 3, the first adjacent horizontal distance is greater than 0, and the second adjacent horizontal distance is 0, which meets the determination condition. Figure 4

[0086] In step S404, it is determined whether the first adjacent horizontal distance is greater than or equal to the second adjacent horizontal distance.

[0087] If yes, the type is the third type, and if no, the type is the fourth type.

[0088] In an embodiment, it is determined whether the number of the first bottom edges is 2; if yes, it is determined whether the two first bottom edges respectively intersect with the adjacent side edges; if yes, the type is determined as the third type.

[0089] If the number of the first bottom edges is not 2 and the two first bottom edges do not respectively intersect with the side edges, or the number of the first bottom edges is greater than or equal to 3, the following steps are performed.

[0090] The lowest empty line segment is determined.

[0091] The lowest empty line segment is defined as a line segment remaining after the projection of the top edge removes all the first bottom edges.

[0092] It is determined whether the number of the lowest empty line segments is 2; if yes, it is determined whether the empty line segments do not respectively intersect with the side edges; if yes, the hole is integrated, the multiple empty line segments are combined into one empty line segment after the integration, the integrated hole is of the third type, and the type is determined as the third type; if no, it is determined whether the longest empty line segment intersects with the side edges; if yes, the hole is integrated, the type of the integrated hole is the first, third or fourth type; if no, the type is determined as the third type.

[0093] If the number of the lowest empty line segments is not 2 and is greater than or equal to 3, it is determined whether the longest empty line segment intersects with the side edges; if yes, the hole is integrated, the type of the integrated hole is the first, third or fourth type.

[0094] ​​If not disjoint, the hole is integrated, and after integration, multiple empty line segments are merged into one empty line segment, which is integrated into a third type, and the type is the third type.

[0095] After the above-mentioned integration of the hole is performed and the type of the integrated hole is the first, third, or fourth type, the method returns to the above-mentioned step of determining the corresponding type as the first, third, or fourth type, and step S401 is executed.

[0096] In an embodiment, the method can further include the following steps:

[0097] For any two adjacent wall-penetrating parts, in response to meeting the fusion condition, the expanded rectangles of the two adjacent wall-penetrating parts are fused.

[0098] In an embodiment, the expanded rectangles of the two adjacent wall-penetrating parts are fused, which further includes the following steps:

[0099] For any two adjacent wall-penetrating parts, including a first wall-penetrating part and a second wall-penetrating part;

[0100] According to the size of the first wall-penetrating part and the expansion value, the first wall-penetrating part is first expanded to obtain a first transition rectangle;

[0101] According to the size of the first transition rectangle and the tolerance value, the first transition rectangle is second expanded to obtain a second transition rectangle;

[0102] According to the size of the second wall-penetrating part and the expansion value, the second wall-penetrating part is first expanded to obtain a third transition rectangle;

[0103] According to the size of the third transition rectangle and the tolerance value, the third transition rectangle is second expanded to obtain a fourth transition rectangle;

[0104] In response to the intersection of the fourth transition rectangle and the second transition rectangle, the fourth transition rectangle and the second transition rectangle are fused to generate a fifth mixed rectangle.
