Thanks but the Sketch isn't mine, but one found in internet for control net, you can do the same with Moi3D or Blender LineArt if you use the export PDF and convert to jpg.
this is a conversion from Blender with IGES add-on export. but make too many edges, maybe useful in some cases but I prefer clear drawing with line art.
But as you can see more edges make some issue if the sketches is well done the result is very good.
Greetings.
I've been trying Womp for a while but dont use it anymore.
I am also on Patreon at MagicaCSG thus can say a little
about differences
The main difference for me is called: modeling speed.
MagicaCSG is fast !
Womp is sluggish in comparison. Everthing takes a while to respond.
Which probably has to do that it is an online app.
One reason to consider Womp anyway, are the export possibilities.
There are OBJ, STL, PLY, GLTF, USD, FBX, DAE, X3D
I haven't tested all of them. But they are there.
