How to convert STP to DWG
- Add your .STP file - drop it in the box above or click to browse.
- Convert it to .DWG in a few seconds.
- Download your new .DWG file.
What to expect
- The output is a 3D solid body in DWG model space - dimensioned 2D views require additional manual steps inside AutoCAD.
- Multi-part STP assemblies may flatten on import; Fusion 360 preserves component hierarchy better than AutoCAD's raw IMPORT command.
- AutoCAD's STEP importer was introduced in version 2013; older releases need a third-party add-in.
Frequently asked questions
Does AutoCAD open STP files without a plugin?
Yes, AutoCAD 2013 and later include a native STEP importer - run
IMPORT, choose the STEP file type, and the geometry loads into model space as a 3D solid.Will I get a 2D drawing after converting STP to DWG?
No - the conversion produces a 3D solid body, not a flat dimensioned drawing. Creating 2D layout views from that solid requires manual work inside AutoCAD.
Can I convert STP to DWG for free?
Fusion 360's free personal tier can do it, but commercial use requires a paid plan. FreeCAD exports to
.dxf for free with no commercial restriction - many tools accept DXF in place of DWG.Why does my converted DWG appear empty in some viewers?
Lightweight DWG viewers often skip 3D solid bodies and show only 2D entities. Open the file in AutoCAD and run
3DORBIT to confirm the geometry is present.Programs that convert STP: AutoCAD · Autodesk Inventor · Argon · Creo Parametric · IronCAD · Solid Edge · SolidWorks · TurboCAD
