This class performs fast sewing of surfaces (faces). It supposes that all surfaces are finite and are naturally restricted by their bounds. Moreover, it supposes that stitched together surfaces have the same parameterization along common boundaries, therefore it does not perform time-consuming check for SameParameter property of edges.

Detailed Description

This class performs fast sewing of surfaces (faces). It supposes that all surfaces are finite and are naturally restricted by their bounds. Moreover, it supposes that stitched together surfaces have the same parameterization along common boundaries, therefore it does not perform time-consuming check for SameParameter property of edges.

For sewing, use this function as following:

set tolerance value (default tolerance is 1.E-06)
add all necessary surfaces (faces)
check status if adding is correctly completed.
compute -> Perform
retrieve the error status if any
retrieve the resulted shape
