FAQ

PRT to IGS Conversion

What are PRT files?

PRT is a file extension used by several unrelated formats. Most often it is a part file of a CAD program, a drawing or a 3D model of one component, created in Siemens NX, CADKEY, MegaCAD, or ProCAD. It can also be a print file with commands for a printer or plotter, or a raster picture in CMYK colors prepared for printing. Programs from different developers cannot open each other's PRT files, so it is important to know which program created the file.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
