We have a customer that operates on a low level. They have minimal employees and subcontract out their machining and fabrication. They manufacture a product that the owners invented and have it pretty well refined. In this all there is one part of the product that is custom. So often they come to us and want a part machined one time. They have a hand sketch scribbled up and this is what we have. They now have asked me what I could recommend for a simple sketching program or something to make quick drawings. They are not real technical so it needs to be easy to use and learn. Is Draftsight something I should tell them about or is the learning curve to hard on that? I don't think either of the owners have any experience at all with cad programs so it needs to be super easy. Thanks
