Forums:
I have a code:
BRepPrimAPI_MakeCylinder MKCyl(r, h);
TopoDS_Shape cyl = MKCyl.Shape();
...
BRepBuilderAPI_Transform aBRepTrsf(cyl, aTrsf);//some transformation
cyl = aBRepTrsf.Shape();
How can i get face of shape cyl?
I tryed to use:
TopoDS_Face face=TopoDS::Face(cyl); but it does not work,leading to a breakpoint.What can I do?

Hi Giogii,
Use for this TopExp_Explorer.
Take into account that the mentioned cylinder
has 3 faces (bottom, top and lateral).

Try this:
TopoDS_Shape cyl = MKCyl.Shape();
...
TopoDS_Face cylindricalFace;
for( TopExp_Explorer ex(cyl, TopAbs_FACE); ex.More(); ex.Next() )
{
TopoDS_Face currentFace = TopoDS::Face( ex.Current() );
BRepAdaptor_Surface brepAdaptorSurface( currentFace,Standard_True );
if( brepAdaptorSurface.GetType() == GeomAbs_Cylinder )
{
// be happy
cylindricalFace = currentFace;
break;
}
}
Cheers,
Dennis
