Formate CAD Native

Native CAD Formats refers to formats that are proprietary to specific CAD systems. If you have the ability to read these formats, they will have the most information and be more accurate than Geometric Modeling Kernel formats or Neutral CAD formats.

For this reason it’s always a good idea to ask your customer for the native format (assuming you have the capability to read the the native format).

AutoCAD .dwg, .dxf Both Autodesk R9-2017 R9-2017 DXF is ASCII
CATIA V4 .model Precise Dassault 4.1.9 – 4.2.4 4.1.9 – 4.2.4  
CATIA V5, V6 CATPart, CATProduct, CGR Both Dassault 15-2018 (R28) 15-2018 (R28) File-based support for V6. Note that CGR is Visrep.
Creo .prt, .asm Precise PTC Up to 3.0    
Microstation .dgn Precise Bentley Systems Up to V7    
NX, Unigraphics .prt, .jt, .j_t Precise Siemens NX up to NX11, JT up to 10.2 JT up to 10.2 JT is a compressed visualization format ideal for viewing large assemblies.
Pro/E .prt, .asm Precise PTC Up to Wildfire 3    
Inventor ipt, iam Both Autodesk Up to 2018    
SOLIDWORKS .sldprt, .sldasm Both Dassault 97-2018 97-2017 Writing SOLIDWORKS format requires that the version of SOLIDWORKS you want to write to is actively licensed on the same machine.
Solid Edge .par, .asm, .psm Both Siemens ST9   Best exported as X_T.

Geometric Modeling Kernels

Geometric Modeling Kernels are what Native CAD formats are built upon. Because these formats are strictly managed by the vendors, they are a better source of geometric information than STEP or IGES.

Neutral CAD Formats

Neutral CAD formats are the lowest-common denominator between CAD systems. If your customer does not have the software to read the native CAD file or the geometric modeling kernel format, STEP is your best bet.

IGES .sat, .asat, .sab, .asab Precise ANSI / ASME Up to 5.3 Up to 5.3 International Graphics Exchange Format; this format primarily supports surfaces and is generally the weakest of the translation formats.
STEP .stp, .step Both ISO AP203/AP214, AP242 AP203/AP214, AP242 STEP is the most popular neutral CAD format in the world today, but STEP is not always the best go-to format for translation.

Tessellated Formats

CAD formats are often converted to polygonal formats such as STL and OBJ for the purposes of 3D printing, animation or game development. Polygonal formats are tessellated, or faceted, and as such are an approximation, containing none of the engineering information found in Brep CAD models, such as weight or volume. Note that we have also included NGRAIN’s voxels in this list since, like polygons, voxels are an approximation of CAD geometry.
