I started with TurboCAD Pro Platinum in 2016 and it has become an excellent asset to the products we produce. It is actually easy to use once you take some time to understand the tools and menus. It does require a good high-end computer to run the model renderings, but they are extremely helpful for new factory workers to see the products clearly and to be able to assemble them with the least amount of management time. We use it also for the design of new products and there is not much you cannot do with it after you "play" with all the tools and understand how to use them. And I still have not used all the toolset. I try to learn at least one new tool for each project. I cannot see going with another program, even for complex design work. The accuracy of the drawings and the ability to bring in all sorts of manufacturer's parts to scale and place them in the drawings is easy to do. The vector x,y,z controls are exacting. Using the "extents" to manipulate the position is very precise.
