Description

Technical Field

[0001] The present invention relates to the field of digital information-based building design, and more specifically, to a method for constructing a REVIT parametric variable three-dimensional dimension annotation family. Background Art

[0002] At present, with the development of information technology and the strong promotion of the "Implementation Opinions on Accelerating the Application of Building Information Modeling (BIM) Technology", the digital transformation of all walks of life has become more and more mature. As a traditional basic industry, the construction industry has also gradually begun to accept the application of digital technology. BIM technology, as a representative of it, has become an indispensable tool in the process of building design, construction, and operation.

[0003] In the application of BIM, three-dimensional display is often required in the rendering situation, and three-dimensional display is often used in construction technical disclosure. Therefore, a three-dimensional display model with dimension annotation is often needed to make the construction technical disclosure clearer and more explicit. However, the dimension annotation provided in the mainstream software Revit for expressing building information models is difficult to use and has certain limitations. It cannot even be synchronized with all rendering software, resulting in the inability to clearly express the component dimensions and their mutual relationships during construction technical disclosure. Moreover, most rendering software (such as Enscape, Twinmotion, etc.) does not have the function of dimension annotation. Therefore, the original technology cannot meet the requirements of daily technical disclosure and on-site use. Based on this background, Revit is redeveloped to solve the problem of three-dimensional dimension annotation by building a self-built parametric family library. Summary of the Invention

[0004] The present invention aims to overcome the poor versatility of the dimension annotation function provided in the mainstream software Revit for expressing building information models, the inability to achieve parameterization, the difficulty in operation, and the inability to be used for display in rendering software, and provides a method for constructing a REVIT parametric variable three-dimensional dimension annotation family.

[0005] The present invention aims to solve the above technical problems to at least some extent.

[0006] The primary object of the present invention is to solve the above technical problems, and the technical solution of the present invention is as follows:

[0007] A method for constructing a REVIT parametric variable three-dimensional dimension annotation family, the method comprising the following steps:

[0010] S3: Create a dimension rod family using a face-based metric generic model;

[0011] S4: Import S2 and S3 together into S1 to produce a parametric variable 3D dimension family.

[0012] Further, the specific steps of S2 include:

[0013] S2.1: Select a metric generic model file in the rft format and create 7 model texts respectively;

[0014] S2.2: Select a face-based metric generic model file in the rft format, import the rft file exported by S2.1 into the file, and set 10 reference planes (3 horizontal and 7 vertical);

[0018] Further, the specific steps of S3 include:

[0019] S3.1: Select a face-based metric generic model file in the rft format and create a dimension rod family model group using the method of creating a new loft;

[0020] S3.2: For the model group described in step S3.1, create a reference line along the center line of the dimension rod and lock the left and right ends of the dimension rod to control the rotation angle of the dimension rod, the extension of the dimension line, the dimensioning capture distance, the gap between the dimension line and the primitive, the dimension length, etc.;

[0040] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0041] The technical solution adopted in this specific implementation method is as follows: Based on the Revit software, a new family is created. To address the deficiencies of the built-in 3D dimensioning function in the original software, instead of using the built-in 3D dimensioning function, the most basic "Metric Generic Model Based on Lines" is directly adopted. First, a text family and a marking rod family of the "Metric Generic Model Based on Faces" are created, and then nested into the Metric Generic Model Based on Lines. Among them, constraints are created and relevant parameters are set to form the required parametric variable 3D dimensioning family.

[0042] Example 1

[0043] A construction method for a REVIT parametric variable 3D dimensioning family, the method comprising the following steps:

[0044] S1: Create a parametric variable 3D dimensioning family using the Metric Generic Model Based on Lines. The 3D dimensioning family includes: a text family and a marking rod family;

[0045] S2: Create a text family using the Metric Generic Model Based on Faces;

[0046] S3: Create a marking rod family using the Metric Generic Model Based on Faces;

[0047] S4: Import S2 and S3 together into S1 to produce a parametric variable 3D dimensioning family.

[0048] Further, the step S2 specifically includes:

[0049] S2.1: Select a Metric Generic Model file in the rft format, as Figure 1 shown, and create 7 model texts respectively;

[0050] S2.2: Select a Metric Generic Model file based on faces in the rft format, import the rft file exported in S2.1 into the file, and set 10 reference planes (3 horizontal and 7 vertical);

[0051] S2.3: Select a Metric Generic Model file in the rft format, as Figure 2 shown, create 2 prefix model texts and 2 symbol texts respectively, and import them into the rft file in S2.1;

[0052] S2.4: As Figure 3 shown, define the model text parameters, set the corresponding formulas, decompose the marked length into units of tens, hundreds, thousands, ten thousands, etc., as Figure 4 shown, and display the values, symbols, and units of each digit by association;

[0053] S2.5: As Figure 5 shown, name and save the completed text family in a unified format and test it.

[0054] Further, step S3 specifically includes:

[0055] S3.1: Select a face-based metric generic model file in the rft format, as Figure 6 shown, and use the method of creating a new loft to create a family model group of the marking rod;

[0056] S3.2: For the model group described in step S3.1, as Figure 7 shown, create a reference line along the center line of the marking rod and lock the marking rods at both ends to control the rotation angle of the marking rod, the extension of the dimension line, the capture distance of the dimension annotation, the gap between the dimension line and the primitive, the marking length, etc.;

[0057] S3.3: As Figure 8 shown, define the parameters of the marking rod family model and set the corresponding formulas;

[0058] S3.4: Name and save the completed text family in a unified format and test it.

[0059] Furthermore, step S4 specifically includes:

[0060] S4.1: As Figure 9 shown, select a line-based metric generic model file in the rft format, and import the rfa file of the text family generated in step S2 and the rfa file of the marking rod family generated in step S3 into the file together;

[0061] S4.2: After defining the relevant parameters, name and save the completed parametric variable 3D marking family in a unified format and test it.

[0062] As Figure 10 shown, the schematic diagram of the parametric variable 3D marking in the rendering software can be automatically displayed in the rendering software after freely selecting the dimension to be marked in the Revit software.

[0063] As Figure 11 shown, the schematic diagram of the 3D marking after changing the wall spacing, and the 3D marking dimension can be automatically changed as the marking spacing changes.

[0064] As Figure 12 shown, free 3D marking of the dimensions in any direction such as vertical, horizontal, diagonal, angular, or for special-shaped components can be performed, solving the limitation problems of the original software.

[0065] As Figure 13As shown in the figure, it can be parameterized to meet the actual needs of different people. The style, color, spacing of the text, and the style and color of the marking rod can all be changed according to requirements, while mainstream modeling software such as Revit or rendering software cannot achieve this. Any form of text, digital prefix or suffix can be added to the 3D marking, which is convenient for the description of text and dimensions of key parts during construction disclosure.
