One of the prime examples for prt to stp conversion would be an early Solidworks (.prt) file to STEP product data file transfer (.stp). Unless you have access to SolidWorks, you will have to rely on some 3rd party CAD programs or dedicated converters. Convert Solidworks To Stl Online Converter 11 Answers If you have GrabCAD Workbench, you can convert any.sldprt file to STL via Right-Click, Download As. Then choose.stl format. Plenty of programs support SolidWorks formats, yet most of them are commercial and not available for free. Although some sldprt to stl converter online exist, much like is the case with any other web based converter, the results may not be perfect. Updated: March 6, 2020.

Explore frequent use casesWhat is Solidworks format?

Approximately 23% of CAD professionals globally use SolidWorks on daily basis. Together they generate tremendous volume of 3D files in native format, which are troublesome to feed into 3rd party major and minor CAD systems due to format specifics. SolidWorks files (previous to version 2015) use the Microsoft Structured Storage file format. This means that there are various files embedded within each SLDDRW (drawing files), SLDPRT (part files), SLDASM (assembly files) file, including preview bitmaps and metadata sub-files. CAD Exchanger seamlessly reads SolidWorks data and converts to the file format of your choice.

| Description | SolidWorks CAD program 3D image format file with a three-dimensional object or part that can be combined with other parts into a single assembly (SLDASM) file. Adobe Acrobat 3D or Acrobat Pro 9 and newer can be used to open SLDPRT files. | STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact. |
| Technical details | An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary. | |
