Detailed Description

Provides methods to.

• identify possible contiguous boundaries (for control afterwards (of continuity: C0, C1, ...))
• assemble contiguous shapes into one shape. Only manifold shapes will be found. Sewing will not be done in case of multiple edges.

For sewing, use this function as following:

• create an empty object
• default tolerance 1.E-06
• with face analysis on
• with sewing operation on
• set the cutting option as you need (default True)
• define a tolerance
• add shapes to be sewed -> Add
• compute -> Perform
• output the resulted shapes
• output free edges if necessary
• output multiple edges if necessary
• output the problems if any
