I am 68 years old, married. I am an electrical engineer and vice president of MNA in Marietta GA. We design, invent, and build automation machinery. Our mechanical engineers use SolidWorks 3D CAD and the electrical engineers use SolidWorks Electrical. For an electrical engineer who wants to occasionally draw 3D mechanical drawings, Shapr3D is 5 to 10 times less costly than SolidWorks.
