Inkscape and Prosthetics

I had a thought that maybe using Difference instead of Union would help with this problem.  Probably not, but worth a test.  But before I got to testing that, I had yet another thought   

In the attached file, I recreated that original design that I made before.  I made it in 2 different ways.  The way I made it originally is in Layer 2.  In Layer 1 is the step just before we get to what's in Layer 2.  I wonder if Blender can accept the drawing as in Layer 1?

In Layer 1, everything is still a stroked path.  In Layer 2, I used Stroke to Path, and now it's a filled path with no stroke.  But I just had the thought, that maybe Blender can accept the stroked path, and maybe it has a better way of converting it, to avoid this problem?  Then Blender does the conversion instead of Inkscape.

Lazur can probably answer that as well?

Hi.

why Inkscape does have this limit in the number of nodes that it can create without mixing the filled and empties parts?
Is there any chance to raize this number?

My guess what you are experiencing is only a rendering issue of mixing up the fill rule, usually also producing different look at different zoom levels. That doesn't alter the drawing itself, if you switch to outlines only rendering mode you can check it works all the same (Ctrl+5 twice on the numpad).


For fitting the text into shape, once you convert it to a single path you may try the envelope lpe or the (pre)0.92's lattice deformation lpe.

Hello!

The 'parametric' CAD software as Solidworks (not sure FreeCad too) can achieve a clean use of a vector texture to extrude it. I did it on a cylinder (must remember how, but it was easy)
Therefore, it would indeed be the best way to do the thing, BUT the difficulty here is to convert a scan into a fully functional 'parametric' file: .sldprt or else.
I suppose that these 'parametric' programs use curves and the software specialised for orthopedy are sharing the same principles which I understand as being curves (vectors).
I know that these programs achieve to convert a scan into a usable file (so, into curves) but I already searched much in this way and spoke with experienced multisoft 3D modelers that told me that so many people tried and failed.

Sorry for the too technical details but actually this is a node question for a real productive method. The CEO(director?) of a company producing 3D printed prosthetic sockets contacted me through linkedin and somebody in his team shoud be able to answer me that question... I'll let you know
