Was asked at work the other day if I knew anything about freeform in Autodesk Inventor.
My answer was an unreserved no. hadn't a clue what it was.

So I made this head using it, I usually make useful things so totally not my comfort zone.
I in no way think its brilliant but I am pleased to have made my first thing with this tool.

I have learned a fair bit about it and already see lots of future possibilities.
If you have a spare bit of time between prints give it a go, it actually strangely feels good in the hand if that makes any sense nice and smooth.
