Wow.
I use Fredo box stretch frequently but didn't know you could move the scaling "plane". 😳
That makes it even better.
I guess we learn something every day...

You are right.

I didn't know this neither. 😳

That's why I never dared to put "level of SketchUp - ADVANCED".

Thank you so much for your help chaps, it is really amazing to see how Sketchup has been redefined as a program, the organic modelling is exactly what we need!!

The examples is the thread suggested by baz really give a newbie like me a great idea of how the proxy shape guides Artisan to create the curves...very, very interesting.

We will keep on learning the hard modelling side so we have understanding and flexibility to create the proxy's we need, thanks again, you have all been very helpful.

Hi Ben, hi folks.

It may prove to be simpler to do it all using SketchUp. Doing this simple design might prove a good way to learn the software. In the following example, I used the default 24 segments for circles and ellipses and 12 segments for arcs. Using more may yield a better result. The completed figure comprise 1608 edges. Using something like 96 edges for the larger circles would set the count to 1896 which is not much. Even quadrupling everything from this value would yield 7584 edges (circles and ellipses with 384 segments and arcs with 48 segments). Maybe this would be OK for CNC machines.

See this SU file for ideas.
