How to make cone with sheet metal and unfold sheet metal  part ?

This post might help, the file in the screencast is in the same thread a couple posts up. To unfold with sheet metal at the moment you need a short flat section.

Besides the flat part, you also need to have a small gap.

Maybe in the future it's possible to have a completely closed circular object.

Now afterwards I delete the small parts and it automatically becomes a solid closed object.

Here some pictures of how I do it.

There are probably different ways to do it.

I've also tried to extrude to get rid of the gap but because of the flat part,

but the circle is never perfect.

The way I do it now leaves a perfect shape.

But be warned, you will loose the unfold capability after you delete this !

This is the folded cylinder, you notice 2 flat parts and a gap.

Here's a close up.

Select every face with ctrl, select the faces on the inside of the cylinder and bottom as well.

Now press delete and the magic happens, a perfect cylinder appears !!

Of course this is all much easier in mature MCAD software like Autodesk Inventor Professional.

See Attached Fusion technique.
