I have an SVG file of a line drawing. When I import it into Tinkercad it generates a 3D version with the width of the lines remaining constant along the Z-axis (as expected). I would like to generate a similar STL but with the line width narrowing for increasing values of Z. (Similar to the Bevel option in some of the Tinkercad Text shapes).

Can anyone point me at a tutorial on how to do this in Tinkercad, Blender, Meshmixer or Open SCAD?

  • $\begingroup$ I think this might depend on exactly what shape/file you're dealing with and how much of a bevel you're wanting to add. It might be worth adding screenshot(s). $\endgroup$

In OpenSCAD you could create a bevel using the minkowski transformation by transforming the curve using tapered shape such as a pyramid or as I do below a tapered cylinder:

minkowski() {

  cylinder(h = 20, r1 = 10, r2 = 1); 

Example result in OpenSCAD
