Description

Technical Field

[0001] This invention belongs to the field of building information modeling technology, and in particular relates to a method for batch creation of parking space models based on Revit combined with Dynamo, enabling automatic creation of building parking spaces during the use of Revit using the Dynamo plugin. Background Technology

[0002] BIM technology is a visualized digital building model built based on advanced 3D digital design solutions. In the design phases of bridges, tunnels, and architectural engineering, BIM technology enables rapid modeling, model calculation, drawing output, quantity surveying, collaborative design, digital information-based construction, construction simulation, and the creation of 3D digital models containing complete engineering information, achieving consistency with the construction site and thus improving work efficiency. However, there are still shortcomings in the batch creation of components from geometric CAD drawings. For example, creating a parking space model requires identifying layers to create parking spaces in batches, and the size, orientation, and form of the parking spaces must match the drawings.

[0003] Traditional secondary development processes using Revit API are time-consuming, costly, and technically demanding. They are not easily mastered or implemented by architectural engineers.

[0004] Dynamo is a visual programming software launched by Autodesk in recent years. It uses the same programming mindset and can achieve the same functions as traditional Revit secondary development. However, it is different from traditional Revit secondary development. It is based on the concept of computational design and uses a "visual programming language". It has a low learning cost. Even if you don't know programming, you can simply use nodes to design. It is currently widely used abroad.

[0005] Therefore, using the Dynamo plugin in Revit to parametrically modify building components is a very convenient method. How to leverage the functionality of the Dynamo plugin to achieve unified construction and design of parking spaces, thereby improving the modeling efficiency of BIM modelers, is a problem that needs to be solved. In particular, regarding repetitive components in architectural design, simplifying repetitive parking space designs using Dynamo is of great significance and importance in improving the efficiency of modelers. Summary of the Invention

[0006] The purpose of this invention is to provide a method for batch creation of parking space models based on Revit and Dynamo. By using the Dynamo plugin during the Revit process, a method for automatically creating parking spaces in buildings is achieved. Modular construction is adopted to complete an integrated node for automatic parking space creation. By running the parking space creation node, the parking space design process in different building designs can be realized, which solves the problems of long development time, high cost and high technical threshold of existing Revit.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention discloses a method for batch creation of parking space models based on Revit and Dynamo, comprising the following steps:

[0009] Step S1: Load the required parking space layout CAD plan into the Revit model;

[0010] Step S2: Pick the required drawing using the Dynamo plugin;

[0011] Step S3: Read various parking space lines from the drawing using the Dynamo plugin;

[0012] Step S4: Using Dynamo's visual programming, convert the Element line type in Revit into Geometry lines in Dynamo, and read the information of each PolyCurve in list form;

[0013] Step S5: Use the Dynamo plugin to filter and determine the parking space outline and the parking space line; use the NumberSlider slider to set the length value of the parking space outline according to the different sizes of the parking spaces.

[0014] Step S6: Using the Dynamo plugin, generate BoundingBoxes from the Geometry of the parking space outlines in the list; query the two points BoudingBox.MaxPoint and BoudingBox.Minpoint;

[0015] Step S7: Using the Dynamo plugin, take the parking space insertion point P1 as the starting point and the parking stop center point P2 as the ending point, use Vector.ByTwoPoint to form a vector, and use Normalized to normalize the vector;

[0016] Step S8: Using the Dynamo plugin and the Vector.AngleAboutAxis node, calculate the rotation angle of the parking space unit vector and the Y-axis unit vector around the Z-axis;

[0017] Step S9: Using the Dynamo plugin, use the FamilyInstance.ByPointAndLevel node to select the center point of the parking space as the insertion point;

[0018] Step S10: Using the Dynamo plugin, rotate the parking space angle using the FamilyInstance.SetRotation node;

[0019] Step S11: Using the Dynamo plugin, add parking space numbers to the parking spaces and express them in the Revit model using linked model text.

[0020] As a preferred technical solution, in step S5, when the Dynamo plugin determines and filters the parking barrier lines and parking space outlines, it combines the List.FilterByBoolMask node with the Math inequality node to filter out the parking barrier lines as inlist and the parking space lines as outlist.

[0021] As a preferred technical solution, in step S6, a straight line is generated between two points using the Line.ByStartPointEndPoint node; the parking space insertion reference point P1 is found using the Curve.PointAtParameter node with the parameter set to 0.5; the center point P2 of the parking space is found using the same method; a vector is formed using Vector.ByTwoPoint; and the vector is normalized using Normalized.

[0022] As a preferred technical solution, in step S9, the Revit parking space family prepared for the project is selected using FamilyType, and the corresponding model is assigned an elevation-based model.

[0023] The present invention has the following beneficial effects:

[0024] This invention provides a method for automatically creating parking spaces in Revit using the Dynamo plugin. It employs modular construction to complete an integrated node for automatic parking space creation. By running the parking space creation node, the parking space design process in different building designs can be realized, improving design efficiency and expanding the existing Revit modeling functions.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 As shown, this invention is a method for batch creation of parking space models based on Revit and Dynamo, including the following steps:

[0038] Step S1: Load the required parking space layout CAD plan into the Revit model;

[0039] Step S2: Pick the required drawing using the Dynamo plugin;

[0040] Step S3: Read various parking space lines from the drawing using the Dynamo plugin;

[0041] like Figure 2 As shown, step S4: Through Dynamo's visual programming, the Element line type in Revit is converted into Geometry lines in Dynamo, and the information of each PolyCurve is read in the form of a list;

[0042] like Figure 3-4 As shown, in step S5: the Dynamo plugin is used to filter and determine the parking barrier lines and parking space outlines; the NumberSlider slider is used to set the parking space outline length value according to different parking space sizes; when the Dynamo plugin judges and filters the parking barrier lines and parking space outlines, the List.FilterByBoolMask node is combined with the Math inequality node to filter the parking barrier lines into the inlist; the parking space lines are placed in the outlist.

[0043] For example, the outline of a regular parking space is 15400; the outline of a mini parking space is 13000. The List.FilterByBoolMask node and the Math inequality node are combined to filter out the parking space lines as inlist; the parking space lines are placed in outlist.

[0044] like Figure 5 As shown, step S6: Using the Dynamo plugin, generate BoundingBoxes from the Geometry of the parking space outline in the list; query the two points BoudingBox.MaxPoint and BoudingBox.Minpoint; use the Line.ByStartPointEndPoint node to generate a straight line between the two points; use the Curve.PointAtParameter node with the parameter set to 0.5 to find the parking space insertion reference point P1, and use the same method to find the parking space center point P2, use Vector.ByTwoPoint to form a vector, and use Normalized to normalize the vector.

[0045] like Figure 6 As shown, in step S7: using the Dynamo plugin, take the parking space insertion point P1 as the starting point and the parking space center point P2 as the ending point, use Vector.ByTwoPoint to form a vector, and use Normalized to normalize the vector.

[0046] like Figure 7As shown, in step S8: using the Dynamo plugin and the Vector.AngleAboutAxis node, calculate the rotation angle of the parking space unit vector and the Y-axis unit vector around the Z-axis. Since this angle is a double-precision value, use Math.Round to round the angle.

[0047] like Figure 8 As shown, step S9: Using the Dynamo plugin, use the FamilyInstance.ByPointAndLevel node to insert the center point of the parking space as the insertion point; use FamilyType to select the Revit parking space family prepared for the project, and assign the corresponding model based on elevation.

[0048] like Figure 9 As shown, step S10: Using the Dynamo plugin, rotate the parking space angle using the FamilyInstance.SetRotation node;

[0049] Step S11: Using the Dynamo plugin, add parking space numbers to the parking spaces and express them in the Revit model using linked model text.
