I am designing plastic parts, so every face has a draft angle. Often I need to align a sketch feature to a wall of my object. If it was square it would be a simple case of projecting the edge of the wall and aligning to that. When there is a draft, projecting the wall edge or its face does not give you a line where the face meets the sketch plane so it is impossible to use this method.
The solution to every Inventor problem seems to be a work around. Here are the two that I use (see attached)
1) Calculate where the face meets the sketch plane. Project the edge of the face then calculate where it meets the sketch as = SketchPlaneOffset * sin(Draft). This is OK for simple examples but tricky for more difficult ones, like aligning to a curved surface (see attached). This is CAD so the computer should be doing the calculations for me.
2) Split the face by the sketch plane and then align to the projected edge of the new face. It should not be necessary to slice up my object just to align features to it.
Does anyone know the proper method to align a feature to a sloping or curved face without manually calculating anything or slicing up the object?
Many Thanks
