[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0058] Embodiment 1

[0059] An embodiment of the present invention provides an automatic modeling method for an air chute with component family positioning. Specifically, the present invention can be implemented in software such as REVIT, as Figure 1 shown, including the following steps:

[0060] S101. Generate a planar orientation line drawing of the air chute on the xy plane according to the straight chute section orientation of the air chute.

[0061] Among them, each line in the planar orientation line drawing corresponds to a straight chute section in the air chute. For example, the planar orientation diagram of a certain air chute is as Figure 2 shown. There are 5 lines in the planar orientation diagram, namely P1P3, P2P3, P3P4, P4P5, and P5P6. Each line corresponds to a straight chute section in the air chute. The generation method of the planar orientation line drawing includes: specifically, it can be drawn and generated by the user according to the air chute, or it can be automatically generated through the lengths of each straight chute section input by the user and the angles between them.

[0062] S102. Mark the position corresponding to the feed port of the air chute in the planar orientation line drawing as the head end point, and mark the position of the discharge port as the tail end point.

[0063] As Figure 2 shown, P1 and P2 correspond to the feed port of the air chute, and P6 corresponds to the discharge port of the air chute. Therefore, P1 and P2 are marked as the head end points, and P6 is marked as the tail end point.

[0064] S103. Use the head end point or the 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, so as to convert the planar orientation line drawing into a three-dimensional orientation line drawing.

[0065] During implementation, the head end point or the tail end point can be used as the starting point for assignment. In this embodiment, taking the tail end point P6 as the starting point, 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 can be obtained according to the type or model of the air chute to be modeled.

[0066] S104. Obtain the inclination angle and groove width of each straight groove section in the air chute, and set the angle between each line in the three-dimensional trend line diagram and the xy plane as the inclination angle of the corresponding straight groove section, and set the width of each line as the groove width, so as to convert the three-dimensional trend line diagram into a three-dimensional trend diagram.

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

[0068] S105. According to the number of lines connected at each intersection point in the three-dimensional trend diagram, determine the type of connecting member placed at each intersection point.

[0069] Specifically, if the number of lines connected at the intersection point in the three-dimensional trend diagram is two, the type of connecting member placed at this intersection point is a bent groove;

[0070] If the number of lines connected at the intersection point in the three-dimensional trend diagram is three, the type of connecting member placed at this intersection point is a three-way groove;

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

[0072] For example Figure 2 As shown, the intersection points are P3, P4, P5. P3 is connected to three lines, so the type of connecting member placed at P3 is a three-way groove. P4 and P5 are connected to two lines, so the type of connecting member placed at P4 and P5 is a bent groove.

[0073] S106. For the connecting member at each intersection point, respectively obtain the inclination angles of the straight groove sections connected to the inlet and outlet of the connecting member as the inlet and outlet inclination angles.

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

[0075] S107. For the connecting member at each intersection point, according to the groove width, inlet inclination angle, and outlet inclination angle, search the offset value database to obtain the inlet and outlet height offset values of each connecting member in the z direction.

[0076] Among them, the offset value database is used to store the inlet and outlet height offset values of connecting members with different groove widths, different inlet inclination angles, and different outlet inclination angles. The specific method for constructing the offset value database is as follows:

[0077] Obtain the groove width B of various types of connecting members (the groove width B is determined by the air chute model), and use the inlet inclination angle θ in and the outlet inclination angle θout Set to different values respectively;

[0078] According to the slot width B and the inlet inclination angle θ in and the outlet inclination angle θ out values, such as Figure 3 and Figure 4 shown, find the height F from the starting point of the inlet feeding plane 1a of the connecting member to the bottom surface of the connecting member, the height f from the end point of the outlet discharging plane 2a of the outlet 2 to the bottom surface of the connecting member, the distance E from the starting point of the inlet feeding plane 1a of the inlet 1 to the center line of the connecting member, and the distance e from the end point of the outlet discharging plane 2a of the outlet 2 to the center line of the connecting member; wherein, the feeding plane or the discharging plane is generally the canvas layer arranged at the inlet and the outlet.

[0079] Calculate the inlet and outlet height offset values under different slot widths B, inlet inclination angles θ in and outlet inclination angles θ out values according to the following formula:

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

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

[0082] Store the connecting members with different slot widths, different inlet inclination angles, and different outlet inclination angles together with the corresponding inlet and outlet height offset values to form an offset value database, as shown in Table 1.

[0083] Table 1 Partial data of the offset value database

[0084]

[0085] S108. Place the corresponding connecting members at each intersection point in the three-dimensional trend diagram, and adjust the height of each straight slot section connected to the inlet and outlet of the connecting member starting from the starting point according to the inlet and outlet height offset value of each connecting member, so that the connecting member is connected to the straight slot section to form a three-dimensional air chute model.

[0086] For example, for the Figure 2 shown figure, starting from the starting point P6, adjust the inlet straight slot section P4P5 at the intersection point P5 according to the inlet and outlet height offset value, so that the straight slot section P4P5 can be connected to the inlet of the intersection point P5, that is, lower the straight slot section P4P5 by the inlet and outlet height offset value based on the height of the intersection point P5 as the height of the outlet P5 of the straight slot section P4P5, and then adjust the intersection points P4 and P3 in turn. After adjustment, adjust the direction of the connecting member so that the direction of the connecting member is consistent with the direction of the straight slot section. Finally, each connecting member is connected to the straight slot section to form a three-dimensional air chute model, as Figure 5As shown. After the model is generated, the slot width and inclination angle can be modified with one key, and the process is simple and efficient.
