Patch Size is an integer between 4 and 30 and defines the amount of data in a patch when generating patches manually. The higher the number, the more accurate the patch will be, although this will slow down patch fitting and analysing.

Patch Generation Tolerance is the tolerance used to recognize valid intersections between boundary curves and between defining curves and the boundaries when generating patches manually. It is also used to recognize adjacent corners when setting continuity between patches.

Patch Check Tolerance is used during automatic checking of patches. If the maximum error of any patch exceeds the Patch Check Tolerance during fitting, then an error is issued and the patch is highlighted in the tabular feedback in the Output Window.
