This page defines the tolerances that will be used by the tidy geometry tool.
Automatic Rubber Setup - Tidy
Tidy coincident tolerance
Enter the distance between parallel entities that will be treated as overlapping and merged to a single entity.
Tidy gaps tolerance
All gaps, overlaps and entities smaller than this distance will be removed. Choosing a tolerance too large is likely to have a detrimental effect on your design.
