Importing DXF or DWG Files with 3D Solids and 2D Entities as Drawings
When you import a 3D DXF or DWG file that contains 3D solids and 2D entities as a drawing,
• The 3D solids in the DXF or DWG file create the 3D model in session. The 3D solids are assembled as components of an assembly.
• The 2D draft entities in the DXF or DWG file create the 2D drawing in session.
• The 3D solids and the 2D entities are placed in model and paper space, respectively.
• 3D views are created when the 3D solid entities belong to a viewport.
A viewport entity in DXF defines the projection of a model-space object in paper space.
• A viewport is imported as a 2D view when no 3D solids are attached to the viewport.
• The 2D entities that belong to the same viewport as the 3D entities are attached to the 3D views.
• If the DXF or DWG file does not contain 2D data, 3D views are created without the 2D entities attached to them. If the file consists of only 2D data, only 2D views are created.
• The 3D model is associated with the 2D drawing and this association is maintained when you build on the 3D model or modify the drawing.
You can skip the solid entities and selectively import the 2D contents using the intf2d_in_acad_ignore_3d configuration option.

 The intf2d_in_acad_ignore_3d configuration option is available as the Import 3DSOLID entities option on the Import DXF and the Import DWG dialog boxes when the 3D DXF or the DWG file contains at least a single solid entity. This option allows you to import 3D solid entities as views of an assembly. |
