On the File menu, click Settings > Options , and go to the Units and decimals settings.
Modify the units and decimals to suit your needs.
The number located to the right of each option indicates the number of decimals. The number of decimals affects the input and storage accuracy. Always use a sufficient number of decimals.
The settings on the Modeling tab affect the data that is used when you are modeling, for example copying, moving, creating grids, creating points, and so on.
The settings on the Catalogs tab affect the data stored in the profile and material catalogs.
The settings on the Analysis results tab affect the output data.
