[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0058] Example 1

[0059] This invention provides an automatic modeling method for air chute with component family positioning. This invention can be implemented in software such as Revit. Figure 1 As shown, it includes the following steps:

[0060] S101. Based on the direction of the straight section of the air chute, generate a planar direction line diagram of the air chute on the xy plane.

[0061] In the planar orientation diagram, each line corresponds to a straight section of an air chute. For example, the planar orientation diagram of an air chute is shown below. Figure 2 As shown, the planar routing diagram contains five lines: P1P3, P2P3, P3P4, P4P5, and P5P6. Each line corresponds to a straight segment of the air chute. The planar routing line diagram can be generated by the user based on the air chute, or automatically by the user-input lengths of the straight segments and their relative angles.

[0062] S102. Mark the position of the air chute inlet in the planar orientation line diagram as the head end point and the position of the outlet as the tail end point.

[0063] like Figure 2 As shown, P1 and P2 correspond to the air chute inlet and P6 corresponds to the air chute outlet. Therefore, P1 and P2 are marked as the head end and P6 is marked as the tail end.

[0064] S103. Take the head end point or tail end point as the starting point, and set the z-direction height value of the starting point to the height value of the air chute, thereby converting the planar directional line diagram into a three-dimensional directional line diagram.

[0065] In implementation, either the head endpoint or the tail endpoint can be used as the starting point for assignment. In this embodiment, the tail endpoint P6 is used as the starting point, and the z-direction height value of P6 is set to the height value of the air chute. The height value of the air chute can be set by the user or obtained from the type or model of the air chute to be modeled.

[0066] S104, the inclination and the slot width of each straight slot section in the air chute are acquired, and the angle of each line to the xy plane in the three-dimensional line trend drawing is set as the inclination of the corresponding straight slot section, and the width of each line is set as the slot width, so as to convert the three-dimensional line trend drawing into a three-dimensional trend drawing.

[0067] The inclination and the slot width of the straight slot section can be set by the user or acquired according to the model or specification of the air chute.

[0068] S105, the type of the connecting member placed at each intersection is determined according to the number of lines connected at the intersection in the three-dimensional trend drawing.

[0069] Specifically, if the number of lines connected at the intersection in the three-dimensional trend drawing is two, the type of the connecting member placed at the intersection is a bend slot.

[0070] If the number of lines connected at the intersection in the three-dimensional trend drawing is three, the type of the connecting member placed at the intersection is a three-way slot.

[0071] If the number of lines connected at the intersection in the three-dimensional trend drawing is four, the type of the connecting member placed at the intersection is a four-way slot.

[0072] For example Figure 2 As shown, the intersections are P3, P4 and P5, P3 connects three lines, so the type of the connecting member placed at P3 is a three-way slot, and P4 and P5 connect two lines, so the type of the connecting member placed at P4 and P5 is a bend slot.

[0073] S106, for each connecting member at each intersection, the inclination of the straight slot section connected to the inlet and outlet of the connecting member is acquired respectively as the inlet and outlet inclination.

[0074] For example Figure 2 As shown, the straight slot section connected to the inlet of the connecting member at P4 is the straight slot section P3P4, and the straight slot section connected to the outlet of the connecting member at P4 is the straight slot section P4P5, so the inlet inclination of the connecting member at P4 is the inclination of the straight slot section P3P4, and the outlet inclination is the inclination of the straight slot section P4P5.

[0075] S107, for each connecting member at each intersection, the inlet and outlet height offset value of each connecting member in the z direction is obtained by searching the offset value database according to the slot width, the inlet inclination and the outlet inclination.

[0076] The offset value database is used to store the inlet and outlet height offset values of the connecting member with different slot widths, different inlet inclinations and different outlet inclinations. The offset value database is constructed in the following manner:

[0077] The slot width B of various types of connecting members is acquired (the slot width B is determined by the model of the air chute), and the inlet inclination θ in and the outlet inclination θout Set them to different values ​​respectively;

[0078] Based on the groove width B and the inlet inclination angle θ in and outlet inclination angle θ out Value, such as Figure 3 and Figure 4 As shown, find the height F from the starting point of the inlet 1 feed plane 1a to the bottom surface of the connecting component, the height f from the ending point of the outlet 2 discharge plane 2a to the bottom surface of the connecting component, the distance E from the starting point of the inlet 1 feed plane 1a to the center line of the connecting component, and the distance e from the ending point of the outlet 2 discharge plane 2a to the center line of the connecting component; where the feed plane or discharge plane is generally a canvas layer set at the inlet and outlet.

[0079] Calculate the different groove widths B and inlet inclination angles θ according to the following formula. in and outlet inclination angle θ out Import / export height offset values ​​under the following conditions:

[0080] h=F-(E*tan(θ in ))-f-(e*tan(θ out ))

[0081] In the formula, h represents the inlet / outlet height offset value;

[0082] Connecting components with different groove widths, different inlet inclination angles, and different outlet inclination angles are stored along with their corresponding inlet and outlet height offset values ​​to form an offset value database, as shown in Table 1.

[0083] Table 1: Offset Values ​​(Partial Database Data)

[0084]

[0085] S108. Place the corresponding connecting component at each intersection point in the three-dimensional routing diagram, and adjust the height of each straight groove segment connecting the inlet and outlet of the connecting component from the starting point according to the inlet and outlet height offset value of each connecting component, so that the connecting component is connected to the straight groove segment to form a three-dimensional air inclined groove model.

[0086] For example, for Figure 2 As shown in the diagram, starting from the initial point P6, the inlet straight groove section P4P5 at the intersection point P5 is adjusted according to the inlet and outlet height offset values. This ensures that straight groove section P4P5 connects to the inlet of intersection point P5. Specifically, the inlet and outlet height offset value of straight groove section P4P5 is reduced from the height of intersection point P5 to become the height of outlet P5 of straight groove section P4P5. Then, adjustments are made sequentially at intersection points P4 and P3. After adjustment, the direction of the connecting components is adjusted so that their direction aligns with the direction of the straight groove section. Finally, each connecting component is connected to the straight groove section to form a three-dimensional air chute model, as shown. Figure 5The model is generated, and the slot width and inclination angle can be modified by one key, and the process is simple and efficient.
