How to automate generate 3d revit from 2d autocad

Automating the generation of a 3D Revit model from a 2D AutoCAD drawing can significantly streamline your workflow. Here are some steps and tools you can use:

Steps to Convert 2D AutoCAD to 3D Revit

1. Prepare Your AutoCAD File:
2. Clean up your 2D AutoCAD drawing by removing unnecessary layers and objects.
3. Ensure the drawing is to scale and units are consistent.
4. Link AutoCAD File in Revit:
5. Open Revit and start a new project.
6. Use the “Insert” tab to link your AutoCAD file into Revit. Make sure to place it correctly in the center of the view.
7. Create Grids and Levels:
8. Use the linked AutoCAD file as a reference to create grids and levels in Revit. This will help in aligning your 3D elements accurately.
9. Use Revit Tools to Create 3D Elements:
10. Utilize the “Pick Lines” tool to trace over the AutoCAD lines and create walls, floors, and other elements in Revit.
11. Switch between wireframe and hidden line modes to see the AutoCAD drawing and place elements like windows and doors accurately.
12. Adjust and Refine:
13. Trim and extend walls, adjust levels, and refine your model to match the 2D drawing.
14. Turn off the imported AutoCAD layers to view only the Revit model.

Tools to Automate the Process
