Hi,

A few days ago I was solving a couple of cases(programming, post-processors) for rotary milling and demonstrated how it can be done inside CATIA using a Multi-Axis Curve MO. However, it requires some extra effort and know-how to create an helix curve on a shape which is not round. Below is a link to the thread at COE.org where I posted a small video clip and a detailed explanation on it.

I think it would be a good option to have inside 3DX and CATIA.

Yesterday, I updated my Fusion360 and looked at this toolpath. It is amazing what these guys are doing at a fraction of a cost. It looks like they have it for over a year now. And I hate to say we don't have such capability in V5 or 3DX.

And one below is for the 4th axis wrap.

It can be done in CATIA but it requires lots of workaround using multiple 5-axis MOs and tons of NC-Geometry to be made. I did it a long time ago in V5 on a somewhat complex shape. Here is a link to another post of COE.org
