Overview
The tolerance range used when matching apertures for each item in the plots. If no exact match for an item is available in the current aperture list, the software checks to see if a larger aperture exists within this tolerance range and uses it instead.
If no suitable aperture exists within the tolerance range, the software will attempt to "paint" with a larger aperture to create the required shape. This requires that a suitable larger aperture is available, and that this aperture can be used for "painting".
Note: Match tolerances are normally only used when you are targeting a vector photoplotter, which require a fixed, or supplied aperture file. They will not be required if the apertures have been created from the PCB. If match tolerances are not required they should be left at the default of 0.005 mil.
