Luthiers using Freecad
Hello!
I am new to this forum because I have a problem with the Marz guitar Workbench. When I draw a headstock in Inkscape and then import it into Workbench I get error messages. The Inkscape drawing contains a path "contour" and a path "midline". The path "midline" intersects the path "contour" exactly in the middle of the vertical line. Always the error message: "contour path and midline path must intersect where the neck will be anchored."
I have been trying to find the error in my drawing for several days now. Can someone help me here? I have attached screenshots of my drawing and the workbench. When I open the import on the left, I have eight contours instead of one. I do not know what to do.
Thanks in advance for the answers.

Re: Luthiers using Freecad
FreeCAD's lines have a (theoretic) width of 0, and have no contour or midline or similar. So it is best to set the line thickness to 0 and remove all the other fancy stuff.

Re: Luthiers using Freecad
without a file we lose ourselves in conjecture
a JPEG may give a clue: it only needs to have a cross section: the vertical line must be a construction line (in blue)
all vertices must be closed
the lines on either side must be close to each other, not just at the middle line

Re: Luthiers using Freecad
Sorry!
It is a SVG file.
It is a SVG file.
Re: Luthiers using Freecad
That may be true for a file on your harddisc at home. At your home. The files you uploaded are all jpgs.
You will probably not grant us full access to your computer at home, so you can upload here an svg file for further investigation.

Re: Luthiers using Freecad
Hello, papyblaise
I think you are right about the construction line.
But how do I draw this construction line?
My problem is that the marz workbench in freecad needs this SVG file from Inkscape.
I have attached the working example file and my self-drawn SVG file here. Thanks again to all for the answers and please excuse my english. I am writing from Germany.

Re: Luthiers using Freecad
120 dof is unmanageable with B-splines I trace over (as close as possible) and it's better

Re: Luthiers using Freecad
Hello papyblaise!
thank you very very much for your drawing and your effort. But I think I expressed myself wrong. Converting the 2D drawing into a 3D object is not the problem.
The downloadable workbench "MARZ Workbench" for Freecad creates itself the template for the guitar neck, but only with a rectangular headplate as basic shape. With the icon "Insert headplate" you have the possibility to import your own shape drawn in Inkscape. The Workbench then automatically replaces the basic shape of the head plate (rectangle) with the own shape of the head plate drawn in Inkscape. And this is exactly what does not work for me. The shape created in Inkscape must have 3 paths. 1. contour 2. midline 3. transition. My drawing has all these paths but still it does not work.

Re: Luthiers using Freecad
I apologize for having disturbed your system which works so well, and I apologize for having wasted all my time
Re: Luthiers using Freecad
Ask the WB author that is not updating it from March 2022 If I don't go wrong.
As it seems that is @mnesarco you may even PM him, or wait if my mention will make it appear.
