2D extracted from 3D

Hello,

How to identify if a 2D drawing is exported from Revit 3D model?

If you want to know if a PDF file was created in Revit:

In Adobe Acrobat you can view the PDF creator in the document properties:

If you want to know if a DWG file was created in Revit:

1. Open the DWG file in AutoCAD.
2. Enter Filter on the command line.
3. Select XDATA ID from the Filter drop-down list.
4. Click Select.
5. In XDATA ID list, look for an entry for Revit. If such an entry
exists, then the file was created in Revit

If you just want to check if it was exported from 3D model: if your Autocad is not LT, you can try just rotating the drawing in Autocad to see the 3D
