Converting 2D drawings into editable 3D models is a common part of modernizing legacy design data or collaborating with teams that still work primarily in AutoCAD or DraftSight. In our latest 2-Minute Tech Tip, we demonstrate how DWG and DXF files can be imported directly into SOLIDWORKS as sketch geometry, saving time and reducing the need to recreate profiles manually.
Importing a DWG file as editable SOLIDWORKS sketch geometry
The SOLIDWORKS import wizard makes the process straightforward by allowing you to import drawings as either a new part or drawing file. During import, you can selectively bring in only the layers you need, place geometry onto specific planes, and clean up overlapping entities automatically. This workflow also supports importin dimensions and constraints, helping to preserve the original design intent while preparing sketches for 3D features like extrudes, revolves, and lofts. Units can also be selected and modified prior to import as required.
This approach is especially useful for:
- Converting legacy 2D designs into parametric 3D models
- Reusing facility layouts or architectural plans
- Reducing sketching time and minimizing geometry errors
- Collaborating with internal or external 2D CAD users
Utilizing SOLIDWORKS features to turn an imported sketch into solid parametric geometry
Once imported, the sketch entities can be fully constrained and modified using standard SOLIDWORKS tools, making it easy to build intelligent 3D models from existing 2D data. For more complex drawings featuring multiple views and advanced features, a specialized 2D-to-3D toolbar is available.
