24class Sewing from BRepBuilderAPI inherits TShared from MMgt
25
26 ---Purpose: Provides methods to
27 --
28 -- - identify possible contigous boundaries (for control
29 -- afterwards)
30 --
31 -- - assemble contigous shapes into one shape.
32 -- Only manifold shapes will be found. Sewing will not
33 -- be done in case of multiple edges.
34 --
35 -- For sewing, use this function as following:
36 -- - create an empty object
37 -- - default tolerance 1.E-06
38 -- - with face analysis on
39 -- - with sewing operation on
40 -- - set the cutting option as you need (default True)
41 -- - define a tolerance
42 -- - add shapes to be sewed -> Add
43 -- - compute -> Perfom
44 -- - output the resulted shapes
45 -- - output free edges if necessary
46 -- - output multiple edges if necessary
47 -- - output the problems if any
48
49 -- For control, use this function as following:
50 -- - create an empty object
51 -- - default tolerance 1.E-06
52 -- - with face analysis on
53 -- - with sewing operation on
54 -- - set the cutting option as you need (default True)
55 -- - define a tolerance to capture contigous boundaries
56 -- - set if necessary face analysis off
57 -- - set sewing operation off
58 -- - add shapes to be controlled -> Add
59 -- - compute -> Perfom
60 -- - output couples of connected edges (contigous) and
61 -- their original boundary for control
62 -- - output the problems if any
