Boundary Check

The boundary check is used to identify any patches with external edges (that means,, a patch boundary which is greater than the tolerance from any adjacent patches). Any external patch edges are displayed in white on black or black on white and any patches which meet at the corners only are shown in blue. The default tolerance used to evaluate if patch boundaries are common is 0.000001m, which is the tolerance level used by Surface (that means,, if the Boundary check is successful, then subsequent stitching in Surface is possible).
