This isometric pipe sketch lesson using AViCAD tools is part 1 of a 3 part series on iso piping.
Actually it’s a full sample taken from of an online CAD course that I am currently teaching called Shortcut CAD.
Here is the link to that if interested in more learning. There is roughly 9+ hours of CAD lessons for the beginner or CAD user wanting to improve their skills.
