Profile Rails Extruder

Profile Rail Extruder

This addon is meant to extrude a flat face drawing into 3d space.

The extrusion is guided by a rail. This rail can go in any direction.

The extruded shape is not changed by the direction unlike bevel from a curve, the normal blender way to make an extrusion.

Left is an extrusion with ‘Profile Rail Extruder’, right is with the usual Blender way to extrude along a curve. The right extrusion is ‘tapered’.
