OpenSCAD bend procedures
compatibility 2017.x
When extruding DXF files in OpenSCAD, your options are rather limited - the extruded DXF always forms a plane.
This procedure allows to bend the extruded file (or basically any model) on the surface of a cylinder or into a parabola.
Instruction (how to work):
1. Place the target in the paralellepiped from [0,0,0] to ["dimension"].
2. Bend around axis parallel X and with Z-coordinate equal "radius", i.e. F(x,"0","radius")
3. The object will be divided into "nstep" pieces along the Y axis. First piece is not changes. Each next piece will be rotated relative to the axis F(x,"0","radius") arount piece center Y-coord.
Upd: Fix 360 degree included.
