Thank you for your help. I“ll try to get dxf2svg-inkscape
running, as soon I can spare some time for it.
I“m sure, for small dxf-files it will be useful for
my kind of work.
Let me just recall what what made me starting this
discussion about dxf:
- With a 3D-Cad tool (in my case SolidWorks) I rotate
the model into a wanted view.
- From SolidWorks I export a black-white-line vektor
drawing (dxf)
- Convert it to svg
- Import it into Inkscape
However this approach, as Denis has confirmed, does
produce quite a large number of objects.
But all I want is a few vektor lines.
This is why I was trying a different approach via
"Tracing a bitmap":
- With a 3D-Cad tool(in my case SolidWorks)I rotate
the model into a wanted view.
- From SolidWorks I export a black-white-line bitmap
drawing (.tiff-File, high resolution)
- Import the tiff into inkscape
- Auto trace the black-white-line bitmap drawing
Visually I do get an identical vector drawing. However
the trace has then again generated a large number of objects. This time
a large number of filled surfaces, very awkward to manipulate.
But all I want are a few vektor strokes.
Is Inkscapes tracing tool capable of generating just
strokes?? I simply coudn“t find a way to get it done?
For each black line in my bitmap, I just want generate
just a single vector stroke out of a black bitmap stroke.
Is there a tracing tool that can do this kind of thing?
