What is a PRTDOT file

PRTDOT files mostly belong to SolidWorks. PRTDOT files are part templates used in SolidWorks applications. They are built on a Microsoft Compound file format which organizes design data into a structured layout.
These files store pre-defined part settings to speed up the design process. They include information necessary to maintain consistency in part creation.

Use SolidWorks to open and modify these templates.

They provide a ready-to-use framework for new parts.

The internal structure helps manage complex design parameters.

PRTDOT file extension format:

If you know the file format, you can also find out how to open or edit the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the PRTDOT files:
