29class Sewing from BRepBuilderAPI inherits TShared from MMgt
30
31 ---Purpose: Provides methods to
32 --
33 -- - identify possible contigous boundaries (for control
34 -- afterwards)
35 --
36 -- - assemble contigous shapes into one shape.
37 -- Only manifold shapes will be found. Sewing will not
38 -- be done in case of multiple edges.
39 --
40 -- For sewing, use this function as following:
41 -- - create an empty object
42 -- - default tolerance 1.E-06
43 -- - with face analysis on
44 -- - with sewing operation on
45 -- - set the cutting option as you need (default True)
46 -- - define a tolerance
47 -- - add shapes to be sewed -> Add
48 -- - compute -> Perfom
49 -- - output the resulted shapes
50 -- - output free edges if necessary
51 -- - output multiple edges if necessary
52 -- - output the problems if any
53
54 -- For control, use this function as following:
55 -- - create an empty object
56 -- - default tolerance 1.E-06
57 -- - with face analysis on
58 -- - with sewing operation on
59 -- - set the cutting option as you need (default True)
60 -- - define a tolerance to capture contigous boundaries
61 -- - set if necessary face analysis off
62 -- - set sewing operation off
63 -- - add shapes to be controlled -> Add
64 -- - compute -> Perfom
65 -- - output couples of connected edges (contigous) and
66 -- their original boundary for control
67 -- - output the problems if any
