Question

Impossible A-class surfaces?

I'm working on a surfacing problem. I've re-created the problem using very basic features and attached a model.

The crease in this part is marked in red. Is it possible to make a similar shape but with a smooth bevelled surface? It seems like it should be possible, but I haven't yet been able to get my head round how.

There are several ways to get tangency in that zone. Here attached one way. The ways are different according what you need to be closer to your original chamfered surface. (Creo 3.0 part file)

Hi Mauro,

The complication here is that the transition on the lower curve needs to be sharp, not tangent.

This can be a solution to get tangency except for the point of discontinuity.

This is pretty close. It uses a sweep that intersects the block
