have drawn a simple path in inkscape and extruded it with blender, which was not really a problem.
After that I exported the model into x3d and uploaded it to shapeways.
Then I received a mail that said that upload was successful, although something had to be fixed. But when you take a close look at the rendering they have done you can see that the model has some strange edges etc.
See here: http://www.shapeways.com/model/103251/tesselating_lizard.htm l

Trying to let the model print out by the shapeways team I received a email where they told me that the model has some too small dimensions.
But this just cannot be true since the model is really not very fancy, and there are no small dimensions ...

Maybe someone can give me some advice or help me to track down the error ?

I am really sorry that I have to bother you with this, but since I have spend almost two days with this I am close to give up ...

thanks,
quirxi

If you can put up a dxf of the outline, I'll gladly extrude and export it for you.]]> Youknowwho4eva 2010-03-19T15:59:48-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=10977&th=2223#msg_10977

thank you very much for your help !
I have tried to generate a reasonable dxf file from that path, which was not easy at all ...
I hope you can open the attached files ?

thanks for the reply!
The problem is the way how these tesselating things are constructed,
They are a combination of different curves where one curve can be the outside in one part of the drawing and the inside in another part of the drawing.
But I have tried to group these together which did look ok in inkscape ?
Since blender did not recognize the inside and the outside properly I had to fill the drawing, which resulted in another outline, but helped blender to construct a closed shape. Where did you see the stray curve ? I could not see it, altough it has happened that in blender once such a curve appeared, which was not visible in inkscape.

Thanks for you help, I will try to import the shape as single curves into blender now and try to combine it in there.

thanks all for your help - I think have solved the problem now.
Removing some of the single curves and exporting them to stl seems to do the job.
At least I hope so since I have not printed them out yet


thanks and regards,
