| Project wire on surface |

Hi,
I am trying to project a wire on a face that is smaller than the wire with BRepProj_Projection(wire, face, direction). But the projection is cut off at the limits of the face. So after searching everywhere I could not find a way to project the wire on the underlying surface of the face. In older versions there seems to have been a fourth parameter to the BRepProj_Projection that had to do with ignoring the face limits, but it isn't there any more.
Any ideas?
Thanks! |

| Maybe you can create a face from the surface oh the projected face, then you can make the prjection. |

| No, BRepProj_Projection won't accept unlimited faces, it gives me "infinite parameter" error |

Hi Jan,
try these classes:
1) BRepAlgo_NormalProjection
2) BRepOffsetAPI_NormalProjection
void SetLimit (const Standard_Boolean FaceBoundaries=Standard_True)
Manage limitation of projected edges.
3) ProjLib_ProjectedCurve
I think 2) is the class you are looking for.

Hi Alex,
1) and 2) as far as I can see do not offer the option of defining a projection direction. Since I want to project onto a curved surface (not a plane) I am not sure whether the result can be correct without defining a projection direction.
3) I couldn't find any documentation for on http://opencascade.sourcearchive.com/documentation/6.3.0.dfsg.1-1/classes.html

Hi Jan,
sorry I missed that you want to specify the direction.
I thought you only need the flag for the limits.
3) ProjLib_ProjectedCurve I have found at Doxygen of version 6.5.2 but in this class it is also not possible to specify a direction.
If I should find something I'll write it in the Forum.
Regards,
Alex

| I have a wire on a plane which I want to project onto a curved (arbitrary shaped) surface. So I am not sure that the automatically selected projection direction will be what I intend. The direction should be normal to the plane, but from the documentation I suspect that it will be normal to the surface? |
