Inconsistencies in a part (lines not quite parallel, small gaps between "tangent" objects, duplicate elements, etc.) are relatively common, but can cause problems for any program that must scan the part to extract information. To help eliminate drawing inconsistencies, Parametric Design provides several tools that can do limited "cleaning" of parts. The CLEAN commands are:

These commands are functionally independent from the remainder of the Parametric Design software, and should be thought of as a "preprocess" for parts that are submitted for parametric design. The AUTO and SOLVE commands have additional part cleaning capabilities which are described in detail in Advanced Topics and Tips. Each of the CLEAN options described below affects all geometry in the current part.
