As part of our business in the logistics industry, we use several CAD programs (AutoCAD, AutoCad LT) to create drawings for both internal purposes and export to customers. The most important feature is the possibility to have direct access to the original source code as well as all previous versions. This allows us to make sure that new features are not added without reviewing all existing functionality. We also need it for compatibility checking with other software applications. Although there are plenty of free alternatives available on the market, we are very happy with the price/performance ratio of the bechtle products. There is nothing I can complain about. If I had to find anything, it would be the speed of the program. It sometimes takes a while to open new files or save a drawing. Some functions are a little bit cumbersome and not user friendly. Especially when you're working on large projects. But this is minor compared to the overall usefulness. We highly recommend.
