The best part about using CAD DRAW is that I can create my own models without having to go through a bunch of steps. It's very easy for me. I am new to this software but it doesn't have so much features as other similar programs (such as CATIA). I don't like the feature-less design. I also dislike how the software is kind of expensive compared to other options out there. If you're looking for simple designs and quick projects, this is your program! I'm just trying to make furniture, so this program makes sense. It has helped a lot in creating different designs quickly and efficiently. CADD Microsystems is a great tool for creating 3D models of mechanical systems. The software is easy to use and has the capability to create complex models. The software is very expensive and requires a lot of training to use. If you are looking for a simple CAD program for creating models, then this is the software for you. I am using CADD Microsystems to create 3D models of mechanical systems. I am creating models of mechanical systems for the purpose of creating a 3D model and a 2D drawing.
