System of units not compatible with tolerancing standard

This error message is presented when there is a mismatch between the standard specified in the Document Settings Standard tab and document units specified in the Units tab. For example, you have specified DIN as the Active Standard, and the Units are set to inch.

You can fix this issue by changing the units setting to match the Active Standard. In the preceding example, changing the Units to mm resolves the error.

Note: Changing the Active Standard to match the units may result in the removal of all mismatched annotations.
