You can modify accuracy settings in Assembly, Part, and Manufacturing modes. When geometry is copied from one part to another with different absolute accuracy, the source geometry can be invalid for the destination part. For more information about modifying part accuracy settings, search the Help Center.

An assembly can have an accuracy setting that is incompatible with that of a part. For example, an assembly hole or cut feature may not display because the accuracy settings of intersected parts are too high. When assembly accuracy and part accuracy differ, you can easily reset accuracy settings at the assembly level.
