@Jean-Philippe Côté Hi and welcome to the forum. Well done in finding a solution to your problem. It set me thinking and I had a play around and made a line2D function for drawing lines of fixed width in the XY plane. The line is a mesh so can be positioned and rotated in 3D. Probably have a play with colours and textures for it next. Also need to be thinking about closing the line. Much fun yet to be had. Just two options currently, the path for the line and the width of the line. htt
