I hope somebody can give me some tipps although I don't really know how to phrase my problem for a suitable title.

I want to create a path in Inkscape and import it as an SVG to blender. When I create the path only two nodes can be joined, not 3 or more, so I get an overlapping path. overlapping path

When I import the path to blender, bevel it and create a mesh with it, the structure is still overlapping which causes problems when slicing the object for the 3D printer. overlapping mesh structure

Is there a way to avoid overlapping or get rid of it? I hope you know what I mean.

Thanks so much.

  • $\begingroup$ Not with curves. A curve cannot be forked, any given point cannot be connected to more than two points. You would need to convert to a mesh and manually create the intersection. $\endgroup$

  • $\begingroup$ Try splitting that profile into 2 curves in Illustrator, so they are as different objects before importing into Blender. Also if dealing with intersecting tube like shown on screenshot select all and run Ctrl+F > Intersect (Knife), or (Boolean), depending on situation. In some cases it will cut out inner geometry and give a decent non-manifold mesh. At least it would lessen amount of manual work you do while fixing that in Edit mode $\endgroup$

You can do this quite easy with help from TinyCAD add-on and some modifiers.


  1. After importing SVG convert it to a mesh - Alt+C > Mesh from Curve/Meta/Surf/Text.
  2. Enable TinyCAD add-on.
  3. In Edit Mode select two crossing edges and W > TinyCAD > VTX Auto.

    Important! You should have only two edges. Sometimes a little clean up could be needed as in example below. Use X > Dissolve Vertices to do this.


  4. Add Skin and Subdivision (use level as needed) modifiers.
  5. In Edit Mode after selecting all vertices scale them with Ctrl+A and tweak Branch Smoothing in Skin modifier as needed.
