The tool was easy to learn how to use once I actually started using it. It's also pretty intuitive if you're used to other CAD programs which are like that (i.e., AutoCad). The tool has everything you need in order to design piping systems - from creating sections down to working out flows across pumps. There isn't much I disliked about this product; however, there were times when I would have liked more functionality than what was available within the program itself. For example, sometimes I would want to draw two parallel loops so I could check flow rates but there wasn't an option for doing that in one go without having to make two separate cuts. However, it really doesn't matter because all my needs are met here. If you're looking for something to create your own designs then FloCAD might not help you here. However, if you're looking to use pre-built.
