About Importing DXF Files with 3D Data
You can import parts, assemblies, components, and features created in AutoCAD and saved as 3D DXF files. The 3D DXF and DWG files can consist of both 2D and 3D data.
3D data of the following types are imported:
Faceted
Embedded exact ACIS data
3D solid entities
You can import DXF files containing:
Faceted geometry as features of existing parts, new parts or assemblies, or as part or assembly components of existing assemblies.
Embedded ACIS data only as a new assembly or an assembly component.
A combination of 2D entities and 3D solids as drawings. The 3D solids are assembled and viewed as components of an assembly after import.
The units set in the DXF and DWG part and assembly models are retained in the imported models. The Import New Model and the File dialog boxes allow you to select profiles for the import and append tasks. Import log files are automatically generated in the working directory when the import is complete.
Importing Faceted And Embedded ACIS Data
The default model type in the Import New Model dialog box is Drawing when the AutoCAD 3D DXF files contain faceted and embedded ACIS data. To import the faceted data, you must explicitly set the model type to Part or Assembly in the Import New Model dialog box. Embedded ACIS geometry can only be imported as a new assembly or an assembly component. Use the imported 3D geometry for constructing features and creating design models.
Importing 2D entities with 3D Solid Entities
The default model type is set to Assembly in the Import New Model dialog box when the AutoCAD 3D DXF or DWG file contains at least a single 3D solid entity. You must explicitly set the model type to Drawing in the Import New Model dialog box to import the 3D solid entities along with the 2D entities in the files. Entities defined as ACIS geometry (BODY, REGION) are ignored.
