The product has been used for many years in our organization to create CAD drawings with great ease! It's very easy-to use even by nontechnical users; it runs smoothly without any problems or crashes during its operation time (as far as I know). There are no complaints about this tool yet - everything works fine so there isn't anything that needs improvement at all from my side either regarding functionality / features etc.. We're using cad graphics mainly because we need some special functions like creating 3D models which have not be offered before within other tools available out here but now they can easily do via CadGraphics' version too :).
