How to bevel an extruded edge ? (by Mark de Roussier)
Hi folk, I'm having trouble understanding the best way to bevel an extruded edge.

If I extrude an arbitrary closed curve, I end up with three surfaces - let's call them bottom, top, and side. The bottom-side intersection is a line ( closed curve ) and the top-side intersection is also a line ( closed curve ). What I want to do, in effect, is to turn these 'intersections of surfaces' into arcs, in a similar way to the way in which 'tangent arc at point' will create a 2d bevel at the intersection of two lines.

I can think of various laborious ways of doing this, most of which involve creating a 'tool object' which I then use to perform a boolean operation on the extruded shape, but is there a better way ?

I cannot think of a better way, but its is worth noting that you could create the tool as a separate file, and import it multiple times.rotating each import as required. Note also that you will likely run into the nurbs problem, where the workaround is to 'force NURBS surfaces to triangle mesh'.

If you're using a build newer than version 2.3 there are some better ways to do this. It's still not easy and will depend on the shape you're trying to create. The attached file works with current builds and creates a cube with all rounded edges and spherical corners. Definitely a lot of work, but no boolean operations.
