Else find this one! Some similar! ;)

Hidden gems like this sometimes make me regret I'm on MacOS these days.

Michael, could there be any chance of a similar solid creation method? Something like a 2-Rail Sweep made even easier by freehand drawing of the components, combined with automatic Booleans.

Hi Metin,

don't regret that you are using macOS, because there is MagicalSketch available from the creators of Shade3D.
This is actually an old technique, which was many years ago available as plug-in for Shade3D. So, this is
nothing new what Pilou posted.

Thx! Yes very similar! The only default : its' not free! :)

PS You said "as a Plugin" It can't work as stand alone ?

Hi Metin,

> Michael, could there be any chance of a similar solid creation method?

It doesn't seem too likely - it's something that's just generally better suited for generating triangle mesh geometry instead of NURBS geometry.

Hi Pilou,

MagicalSketch is a standalone tool, not a plug-in. It was however many years ago a plug-in for Shade.

@ Stefan Thx for the info!
Guy who ask me about SmoothTeddy said that is the more easy and adapted program for school's kids
(he tryed a lot other) the only lack is a traditional operational export format for a 3D Printing !
So my first post! :)

Personally this program don't works for me (surely java problem) so I can't test it!

Little precision
if the file .asg is present just rename it in .zip
Unzip and you will obtain a file format xlm
