Just a solution to a problem I had this week with missized SVG’s.
Shark / Viacad is very similar in 3d modeling to sketchup for me plus it has nice 2d / 3d cad functions. So I like it. And I have on my computer probably 12 cad systems- but enjoy this one the most, unfortunately it does have some bugs.
But its SVG export is screwed up- it messes up the scale of the SVG to a tiny scale.
Instead use DXF export, then import into easel, then export gcode and import gcode into webcontrol which I use to control the Maslow CNC.
