• SolidWorks SimulationXpress generates a file named partname-SimulationXpressStudy.CWR in the results location folder to save analysis results. Materials, fixtures, and loads are saved in the part document. Saving Result Plots with the Part File.
  • Looking for downloadable 3D printing models, designs, and CAD files? Join the GrabCAD Community to get access to 2.5 million free CAD files from the largest collection of professional designers, engineers, manufacturers, and students on the planet.
  • For SolidWorks Simulation Files, the results are contained in one file with the extension CWR. Other information like study properties, materials, restraints, loads, and contact conditions are saved, in the SolidWorks part or assembly document. Many files are created by the solver during an analysis.

As a company that specializes in CAD Translation, we often get questions about a wide range of CAD file extensions; to make this easier on our customers, we’ve compiled a list of the most common Brep and Visrep formats.

Please note: This is a list of all known CAD File Extensions, not a list of formats that TransMagic can Read and Write. For a list of formats supported by TransMagic products, please visit our CAD Formats page.

This video shows you how to manage Simulation result files (.CWR) with Enterprise PDM. Filecontrol SolidWorks Simulation - result-files (cwr-files) - Duration: 3:29. Jos van Kreij 4,497 views. Try creating a result folder inside the document folder - copy and paste all of the result files (including the.CWR). Then, go into the study properties in the Simulation menu and set the results folder to the one that you just created.

Brep vs Visrep

Brep stands for Boundary Representation, which is a true CAD format. Visrep stands for Visual Representation, which is a polygonal or tesellated format. We are including both Brep and Visrep formats in this listing since there is often confusion as to which is which. Where possible, additional notes are provided for each CAD file extension.

3D PDF.PDFVisrep3D PDF is a great format for sharing geometry with those who do not have access to CAD systems or CAD viewers; all that’s required is the Adobe Reader, which is already on almost all PCs.
3D XML.3DXMLVisrep3D XML is a visualization format developed by Dassault Systemes.
3DS Max Files.3DS, .MAXVisrep.3DS files contain mesh or nurbs information; .MAX files contain all scene information, including mesh data.
ACIS Model & Assembly Files.SAT, .ASAT, .SAB, .ASABBrepACIS is a geometric modeling kernel used in many CAD applications. .SAT and .SAB files are part files, .ASAT and .ASAB files are assembly files. Files that end with B are binary.
Alias Model file.WIREVisrep
AutoCAD Drawing Files.DWG, .DXFBrep and Visrep.DWG files are binary, .DXF files are ASCII. Both formats can contain both Brep and Visrep geometry.
Autodesk Filmbox Format.FBXVisrepPrimarily used for exporting mesh, material and animation data to game engines.
CADKEY File.PRT, .CKDBrepCADKEY is now known as KeyCreator.
CATIA V4 Part & Assembly Files.MODELBrep.MODEL files can represent both parts and assemblies.
CATIA V5 Parts and Assemblies.CATPart, .CATProductBrep

CATIA V6 Part and Assembly Files.CATPart & .CATProductBrepFile format is similar to V5 files.
Collada Object Format.DAEVisrep
Creo Part and Assembly Files.DRW, .PRT, .ASMBrep.DRW are drawing files, .PRT are part files, and .ASM files are assembly files. Creo was formerly known as Pro/Engineer.
Fusion 360 Files.F3Z, .F3D, .CAM360Brep.F3Z files are archive files, .F3D are part files, and .CAM360 are toolpath archive files.
Generic CADD Files.CMP, .GCDBrep.CMP files are component files, .GCD are drawing files.

IGES.IGS, .IGESBrepIGES files are predominately surface files, though the definition does allow for solid models. Read more about IGES, learn why to avoid IGES, and alternatives to IGES.
Inventor.IPT, .IAMBrep.IPT files are part files, .IAM files are assembly files.
JT.JTBothJT, created by Siemens / NX, is unusual in that it can contain both Brep and Visrep content. JT is also compressed about 8:1, so it is a good visualization format for large assemblies.
KeyCreator Part & Assembly Files.CKD, CDLBrepKeyCreator was formerly CADKey; .CKD files are for parts and assemblies, .CDL files are for Wireframe Design files.
Kubotek Design Container File.CKDBrep
Lightwave Object File.LWOVisrep

Modo Scene Format.LXOVisrep
Navisworks Files.NWC, .NWD, .NWF.NWC files are cache files, .NWD are documents, .NWF are file sets.
NX Part and Assembly Files.PRTBrepNX was formerly Unigraphics; one confusing aspect to NX .PRT files is that the same extension is used for both parts and assemblies.
Parasolid Model File.X_T, .X_BBrepParasolid is the geometric modeling kernel used for SOLIDWORKS, Solid Edge, and many other CAD solutions; read more about Parasolid here.
