Hi Gunter,
I'll try to explain here, as a video may be too involved.

So I started by taking the text you posted then vcarving it.... (With no worries of depth)

Here is what it looks like from a top view:



And here in a 3d view: (Note the depth is all over the place)



Then I post the gcode for that toolpath. I run it through a system to create a dxf out of the gcode toolpath, then bring that dxf into MoI:



I did some cleanup. Rebuilding and joining etc.... (The dxf comes out as line segments, so I rebuild them into smoother splines. Maybe somemore time could be spent here)

In this file, I left the dxf line segments in as other colored styles, for reference

So why do this?

I can now use "Engrave" on the path. Engrave allows me to set a depth at the spline level.

I can also use MoI's Edit Frame and "Flatten" the geometry. An just do a flat engrave at a single depth with a Vbit...

Let me know if this is not clear...
