How to convert Pro/Engineer (ProE,Pro/E,.asm,.prt) to DWG (AutoCAD, DXF)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

Pro/Engineer

Creo is a family of Computer-aided design (CAD) apps supporting product design for discrete manufacturers and is developed by PTC. The suite consists of apps, each delivering a distinct set of capabilities for a user role within product development. They generally compete with SolidWorks, UG NX, CATIA, Solid Edge and Autodesk Inventor.

For over 3 decades Okino has been a primary conversion partner of PTC, especially for our core business focussing on the conversion of their native ProE/Creo (ASM and PRT) and ProductView (PVS, PVZ) files.

Their current product naming can be a bit confusing:

• Creo Elements/Pro - previously Pro/Engineer
• Creo Elements/Direct - previously CoCreate
• Creo Elements/View - previously ProductView

Okino licenses the real and actual ProE/Creo runtime toolkits from PTC directly and hence can guarantee perfect file conversions. Suggested conversion methods include:

• Via native 'Creo Elements Pro' (Pro/E) files, .asm and .prt.
  
  
• Via PTC .neutral assembly and part files.
  
  
• Via STEP and IGES files.
  
  
• Via native ProductView PVS/PVZ files.

DWG

DXF and DWG are the native file formats of the Autodesk AutoCAD product since 1982. DWG is the binary file variation to the ASCII DXF file format. These files can be viewed by many programs including Autodesk's free DWG TrueView application. It is a closed file format but has been documented by the Open Design Alliance.

At Okino we consider DXF/DWG to be one of the worst 3D file formats when translating 3D model data between applications (depending on its contents). There is very little understanding about this in the 3D graphics world. As outlined in our "CAD Data Sourcing Suggestons and Rules" page you should ideally use the DWF-3D file format when sourcing from either AutoCAD, Navisworks, Revit and optionally Autodesk Inventor.

Due to deep history, Autodesk software can embed ACIS SAT "BREP solids" data in some of its DXF/DWG files. This is the ideal case as the "BREP solids" geometry definitions lead to cleaner and higher fidelity MCAD file conversions. But even so, it would generally be a safer bet to use a STEP AP214 or "IGES BREP solids" file in such cases.
