A design rule check (DRC) conducts interval inspection of objects. The check of the inner side in a clearance (between different potential) check and self clearance (between these potential) and an outside can be performed.

A design rule check (DRC) conducts interval inspection of objects. The check of the inner side in a clearance (between different potential) check and self clearance (between these potential) and an outside can be performed.

The check which outputted only the minimum clearance part for the object, or took into consideration the inside-and-outside relation of an object again is also possible.
