When using File-->Open to open an import file (DXF, IGS, X_T, SLDPRT, STEP, IPT, ETC) the increments will automatically be adjusted to match the increments defined in the file. In most cases this will result in a Gibbs part file in mm. If you need the file to be in inches please follow these steps:
- Open GibbsCAM
- Create a new part file and be sure the increments are set to Inch and the correct machine type is selected
- Go to File-->Import and import your file
- Go to View-->Shrink Wrap
The resulting file should remain in inches as desired.
