Problems solved by technology

[0004] 2D and 3D design interaction can only be performed by importing DWG format in Revit. Since elements are often copied in part / area during the design process, it is necessary to process the DWG file in AutoCAD first, then export the DWG file, and then import it to Decomposition in Revit, this method of operation is not only unfriendly to the designer’s experience, but also significantly reduces the work efficiency of the designer. At the same time, the line type and text style of AutoCAD will be imported into Revit, adding redundant styles. The project of 2D and 3D design interaction greatly delays the progress of engineering design

Embodiment 1

[0063] Such as figure 1 As shown, the present embodiment discloses a data interaction method of Revit and CAD, the method comprises the following steps:

[0064] S1, read the DWG data in the clipboard;

[0065] Specifically, in this embodiment, the DWG data is copied from the Auto CAD software to the clipboard through the user's copy operation.

[0066] Specifically, the user can select the graphic entity to be copied in AutoCAD, and then use the keyboard combination Ctrl+C to copy, or right-click > clipboard > copy command.

[0067] Specifically in this embodiment, step S1 includes:

[0068] Get all the data in the clipboard; traverse all the data to get DWG data.

[0069] Specifically in this embodiment, the step of traversing all data to obtain DWG data includes:

[0070] Use the first condition to traverse to find all the data that meets the first condition; the first condition is that the format attribute of the data contains "Auto CAD";

[0071] Use the second condi...

Embodiment 2

[0087] Such as figure 2 As shown, the present embodiment discloses a data interaction device for Revit and CAD, including a processor and a memory, the memory is stored with program codes, and the processor executes the program codes to execute the Revit and CAD described in Embodiment 1 data interaction method.

Embodiment 3

[0089] Such as image 3 As shown, the present embodiment discloses a data interaction system of Revit and CAD, which is the corresponding implementation system of the data interaction method in Embodiment 1. Optionally, C# and the relevant code library of calling Revit and CAD can be used to Complete the construction of this system, the specific system includes:

[0090] Reading module 1, used to read the DWG data in the clipboard;

[0091] Building module 2, used to extract entity data in DWG data and construct a data dictionary;

[0092] The obtaining module 3 is used to obtain the pasting instruction input by the user; the pasting instruction includes pasting position and pasting primitive type parameters;

[0093] The conversion module 4 is used to convert the data in the data dictionary into the component model in Revit at the pasted position according to the pasted graphic element type parameter.

[0094] Specifically in this embodiment, the reading module 1 includes:...

Abstract

The invention discloses a Revit and CAD data interaction method, device and system. The method comprises the following steps: reading DWG data in a clipboard; extracting entity data in the DWG data and constructing a data dictionary; obtaining a pasting instruction input by a user, wherein the pasting instruction comprises a pasting position and a pasting primitive type parameter; and according tothe pasting primitive type parameters, converting the data in the data dictionary into a component model in Revit at the pasting position. According to the method, the CAD data in the clipboard can be directly pasted to the Revit software to form the component model, excessive operation is not needed, and data transmission between AutoCAD and Revit is faster and more convenient. When projects needing frequent two-dimensional and three-dimensional design interaction are designed, the working efficiency of designers can be effectively improved, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of BIM, and in particular relates to a data interaction method, device and system for Revit and CAD. Background technique [0002] Design drawing is a key link in construction engineering design. For large-scale, multi-specialty and complex projects, two-dimensional design is difficult to meet the needs of actual projects. Using BIM technology for three-dimensional design drawing has become an effective way to solve this difficulty. Since BIM 3D design is still in its infancy, there are problems such as lack of relevant standards, design processes and tool software, which seriously hinder designers from carrying out BIM 3D design, thus affecting the quality of drawings and design progress. [0003] At present, the most widely used BIM software in the industry is Autodesk Revit. In the process of 3D design in Revit, it is often necessary to copy graphics elements from AutoCAD software to Revit, but the curren...
