FreeCAD Macro to replace all placements with Nullplacements. This is important when using Assembly2 Workbench, to allow correct placement there.

	if not b.Placement.isNull():
	print("!!! Body {} has a non null placement --> resetting!".format(b.Label))

reox / bend_tube.scad

Last active June 2, 2021 18:52

Create a bend tube in OpenSCAD. Work ONLY with openscad >=2016, as the angle parameter in rotate_extrude was introduced there.

	// fine mesh
	fn = 1000;
	// epsilon for clean intersection
	eps = 0.1;


	module tube(inner=5, outer=10, angle=45, length=250){
	// we want the thing in z direction, thus we rotate on x axis
