11 | class MakeRevol from BRepPrimAPI inherits MakeSweep from BRepPrimAPI |
12 | |
13 | ---Purpose: Class to make revolved sweep topologies. |
14 | -- |
15 | -- a revolved sweep is defined by : |
16 | -- |
17 | -- * A basis topology which is swept. |
18 | -- |
19 | -- The basis topology must not contain solids |
20 | -- (neither composite solids.). |
21 | -- |
22 | -- The basis topology may be copied or shared in |
23 | -- the result. |
24 | -- |
25 | -- * A rotation axis and angle : |
26 | -- |
27 | -- - The axis is an Ax1 from gp. |
28 | -- |
29 | -- - The angle is in [0, 2*Pi]. |
30 | -- |
31 | -- - The angle default value is 2*Pi. |
32 | -- |
33 | -- |
34 | -- The result is a topology with a higher dimension : |
35 | -- |
36 | -- - Vertex -> Edge. |
37 | -- - Edge -> Face. |
38 | -- - Wire -> Shell. |
39 | -- - Face -> Solid. |
40 | -- - Shell -> CompSolid. |
41 | -- |
42 | -- Sweeping a Compound sweeps the elements of the |
43 | -- compound and creates a compound with the |
44 | -- results. |
