| Summary | 0028003: Cannot revolve a face with a straight B-spline edge lying on axis of revolution | ||||
| Description | It is not possible to revolve a face if one of its edges is a straight B-spline edge that lies on the axis of revolution. If the B-spline is replaced by a line, the revolution is possible. It is understandable that there are problems if a B-spline is very close to or intersecting the axis of revolution but shouldn't the case when all control points of the spline lie on the axis be supported? | ||||

If the following lines are removed from GeomAdaptor_SurfaceOfRevolution::Load(const gp_Ax1& V), the operation works: if ( Ratio >= 100 ) { Standard_ConstructionError::Raise("Adaptor3d_SurfaceOfRevolution : Axe and meridian are confused"); } Ox = ( (Oz^gp_Vec(PP.XYZ()-O.XYZ()))^Oz); The result is a valid solid according to checkshape. However, it has an edge lying on the axis and bopcheck complains about the self-intersection between the edge on axis and the plane. See "solid with straight spline on axis.png". If the input shape has a line instead of a spline lying on the axis, the resulting solid does not have an edge on the aixs. |
