Many thanks to Jim Foltz for this ruby.
Using this with SketchUp I have been able to create a flat pattern of a part and save it as a DXF for sending to a laser cutter. The prototype part was pressed up today and was spot on!
Embarrassingly for some, they weren't able to create a suitable unfoldable model in Autodesk's Inventor.
So it's not how much the software costs is it.

Dear PeterCharles,

I imagine it was more the inexperience of the chap holding the mouse, as Inventor is pretty powerful.

Having said that, I still like using Sketchup, but anxiously await Inventor Fusion.

Regards,
Bob

Don't think so, nobody could assist on the IV help forum. General opinion is IV is a bit lacking in the sheet metal department.

I would be interested to see the part if that were possible.

Of course you can.
The best Inventor advice I got was to start with the flat pattern and press it up!
I thought that rather defeats the object of creating a model and unfolding it.

Dear Peter,

I do not understand why the help desk for Inventor would say that. I would construct the required finished item as a sheet metal component and then unfold at the end. Inventor has an unfold function to create the flat pattern after the part has been fashioned. Curious!

If you have a few minutes then take a look at http://www.youtube.com/watch?v=4NdE1xh_UrU

Well, I posted the problem on the ADSK Inventor help forum, but got no significant assistance. J D Mather asked me to post what I had got, but I got no reply. Using SU was so simple in comparison and the proof of the pudding is the "cock on" prototype

SU isn't just for designing buildings!
