17 | class TFace from BRep inherits TFace from TopoDS |
18 | |
19 | ---Purpose: The Tface from BRep is based on the TFace from |
20 | -- TopoDS. The TFace contains : |
21 | -- |
22 | -- * A suface, a tolerance and a Location. |
23 | -- |
24 | -- * A NaturalRestriction flag, when this flag is |
25 | -- True the boundary of the face is known to be the |
26 | -- parametric space (Umin, UMax, VMin, VMax). |
27 | -- |
28 | -- * An optional Triangulation. If there is a |
29 | -- triangulation the surface can be absent. |
30 | -- |
31 | -- The Location is used for the Surface. |
32 | -- |
33 | -- The triangulation is in the same reference system |
34 | -- than the TFace. A point on mySurface must be |
35 | -- transformed with myLocation, but not a point on |
36 | -- the triangulation. |
37 | -- |
38 | -- The Surface may be shared by different TFaces but |
39 | -- not the Triangulation, because the Triangulation |
40 | -- may be modified by the edges. |
