To Import or Open AutoCAD DWG Files

Importing DWG files.

The following workflows are available: You can also import and open an AutoCAD file directly as an Associative DWG and create 3D Inventor models of 2D layouts.

• You can open an AutoCAD DWG: You can then view, plot, and measure the file contents. Objects display exactly as they do in AutoCAD.
• You can import an AutoCAD DWG file into a part file. Importing an AutoCAD DWG into a part file produces an associative underlay.
  • You can use the Project DWG Geometry command to project DWG underlay geometry and then extrude the projected sketch.
  • You can create 3D Inventor models based on the DWG geometry created in AutoCAD.
  • The 3D model created in Inventor will associatively update when the 2D geometry changes in AutoCAD.
  • In an assembly file, you can use the Joint and Constrain command to create relationships between a DWG underlay geometry and a part.
• You can import an AutoCAD or Mechanical Desktop DWG file using the DWG/DXF File Wizard.

Open DWG files

To open a AutoCAD DWG file directly in Inventor:

• File Open Import CAD Formats.
• Get Started tab Launch panel Import CAD Formats
• Get Started tab Launch panel Open

Import Associative DWG Underlay files into a Part file

To import into a part file select:

1. To import into file, do one of the following:
   • Manage tab Insert panel Import
   • 3D Model tab Create panel Import
2. In the applicable dialog box, set the Files of type to view the available files.
3. Select the file to import and click open.

You can now use the Project DWG Geometry command to project DWG underlay geometry and then extrude the projected sketch.

After you project DWG block geometry you can extrude the DWG geometry and create 3D features as desired.

Import non-Associative DWG files into a Part file

• In the Sketch environment: Sketch tab Insert panel Insert

Note: You cannot import an DWG file into an assembly. You can open DWG underlay geometry in an assembly file placing a part file that contains DWG model geometry.

Import Mechanical Desktop files (not available in Inventor LT)

You can convert 3D data in existing Mechanical Desktop files to features in Autodesk Inventor part and assembly files. If Autodesk Inventor does not recognize the geometry or features of the source files, they are skipped during translation and the missing data is noted in the browser.

When you import Mechanical Desktop files, no links are maintained to existing files.

Note: You must have Mechanical Desktop on your computer to import files.
