Date updated: October 6, 2026
The 246 file extension is associated with Creo Elements/Pro, PTC's CAD/CAM software for Microsoft Windows. Creo Elements/Pro is also known as Pro/Engineer.
The 246 file contains versioned data from Creo Elements/Pro. It belongs to the software's own data rather than being a general-purpose interchange format.
Creo Elements/Pro is a legacy PTC product name; the related CAD software is now generally marketed under the Creo name. The 246 format is therefore primarily relevant to files created or maintained by older Pro/Engineer or Creo Elements/Pro installations.
On Microsoft Windows, open a 246 file with Pro/Engineer or Creo Elements/Pro. Because the file contains versioned application data, it may not be meaningful when opened separately from the related Creo project or data set.
A 246 file is not normally converted with a standalone file converter. It is versioned application data rather than a general-purpose exchange format.
If the associated Creo Elements/Pro data can be opened, use the software's own save or export functions to create a supported design or exchange file. The 246 file itself may not have an independent exportable representation.
