17 | package BRepPrimAPI |
18 | |
19 | ---Purpose: The BRepBuilderAPI package provides an Application |
20 | -- Programming Interface for the BRep topology data |
21 | -- structure. |
22 | -- |
23 | -- The API is a set of classes aiming to provide : |
24 | -- |
25 | -- * High level and simple calls for the most common |
26 | -- operations. |
27 | -- |
28 | -- * Keeping an access on the low-level |
29 | -- implementation of high-level calls. |
30 | -- |
31 | -- * Examples of programming of high-level operations |
32 | -- from low-level operations. |
33 | -- |
34 | -- * A complete coverage of modelling : |
35 | -- |
36 | -- - Creating vertices ,edges, faces, solids. |
37 | -- |
38 | -- - Sweeping operations. |
39 | -- |
40 | -- - Boolean operations. |
41 | -- |
42 | -- - Global properties computation. |
43 | -- |
44 | -- |
45 | -- The API provides classes to build objects: |
46 | -- |
47 | -- * The constructors of the classes provides the |
48 | -- different constructions methods. |
49 | -- |
50 | -- * The class keeps as fields the different tools |
51 | -- used to build the object. |
52 | -- |
53 | -- * The class provides a casting method to get |
54 | -- automatically the result with a function-like |
55 | -- call. |
56 | -- |
57 | -- For example to make a vertex <V> from a point <P> |
58 | -- one can writes : |
59 | -- |
60 | -- V = BRepBuilderAPI_MakeVertex(P); |
61 | -- |
62 | -- or |
63 | -- |
64 | -- BRepBuilderAPI_MakeVertex MV(P); |
65 | -- V = MV.Vertex(); |
66 | -- |
67 | -- |
68 | -- For tolerances a default precision is used which |
69 | -- can be changed by the packahe method |
70 | -- BRepBuilderAPI::Precision. |
71 | -- |
72 | -- For error handling the BRepBuilderAPI commands raise only |
73 | -- the NotDone error. When Done is false on a command |
74 | -- the error description can be asked to the command. |
75 | -- |
76 | -- In theory the comands can be called with any |
77 | -- arguments, argument checking is performed by the |
78 | -- command. |
