How to convert DWG (AutoCAD, DXF) to IronCAD?


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.

     

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.

     

IronCAD

IronCAD is 3D and 2D CAD design package focused mainly on the mechanical design market. It uses both Parasolid and ACIS modeling kernels to provide computational methods for solving geometric calculations such as calculating blends and shells.

Okino knows of IronCAD well as it used to be called Trispectives, developed by 3D Eye, prior to its August 1998 v1.4 release date.

Converting from IronCAD into Okino software can be handled by STEP AP214, IGES solids, Parasolid, ACIS SAT, VRML2, HOOPS HSF, STL and Wavefront OBJ.

Converting from Okino software into IronCAD can be handled in one of many ways, such as: DXF, STL, VRML and Wavefront OBJ.
