Hi,

I have a question concerning design of a sheet metal cone.

I am having trouble to flatten out the cone correctly. SW gives an impossible shape to the unfolded part. (see example in attachment).

The cone is designed as followed:

- on front plane a construction line for centre and a sketch line for the the cone-shape.

- then a revolved boss/base around the centre line, rotation of 359,9° and thin feature.

- unfold with insert bend.

In my opinion this is the quickest and easiest way to form a cone.

SW help desk suggests to work with lofted bend, witch is much more complicated.

This is the MO I used working with SW2008, recently upgraded to SW2012SP3 and now there's a no go on this way of working.

The example is just a small part, usually the cone is a section of a multibody sheet metal part such as a cyclone, oven jet pipe, ...

Any one suggestions on another simple way of working?
