How to convert Softimage|XSI (.xsi) 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.



Softimage|3D and Softimage|XSI were two well known 3D animation systems written by Softimage Inc. of Montreal Canada. Autodesk eventually came to buy the company in 2008 and then kill off the software in 2014.

Okino had a very long standing relationship with Softimage and its software, having written the main import/export converters for both Softimage|3D and Softimage|XSI in the 1990s.

Conversion to/from Softimage|3D was done with the .hrc and .dsc file formats which are now considered obsolete. In simple terms, you would need to get a running version of Softimage|XSI v7.x on your Windows machine in order to read in older .hrc and .dsc files.

Conversion to/from Softimage|XSI was done with the .xsi v3 and v5 file formats which are still supported in Okino software.



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.
