Does anyone know where in Carrara 6 pro is the chamfer menu ?

TIA

It's called a "Fillet" in C6. You'll find it in the top icon row once in the Vertex room. A best practice is to select the edges you want to Chamfer before selecting the tool. Amount and smoothness of the chamfer can be adjusted in the tools pallet dynamically before hitting enter/return on the keyboard.

Thanks for that - this is what I've found so far - is this the correct way to do it?

Plus what do the radius and range options do?

You can select a single vertex to chamfer or many vertices. If you select a face, all the vertices are selected.

The radius is the size of the chamfer and the range is the number of added vertices that will be added to create the chamfer. You can adjust the settings and then press the return key to finish the action. Before you hit enter, you can change settings and watch what the changes will do to the model.

I guess I should say, if you select a face, all the vertices touching that face will be chamfered.

@MrSparky, I'd suggest playing with the options to find out. ;-)

Filleted edges that intersect must all be selected before choosing the Fillet tool so that the intersecting corners are calculated correctly. Selecting edges individually with the tool will lead to bad corner geometry.

Thanks everyone - playing and finding out what you're saying can happen - but overall think I've cracked this one - so thanks again.
