This software is easy to use, it has an intuitive interface. The CAD design features are very useful as well. I like how you can have multiple files open at once, this makes my work easier when making complicated drawings or diagrams for presentations. It would be nice if we could choose which tool was best suited towards our project that needs doing. When working with complex projects such as drafting large scale industrial designs the time taken gets quite long sometimes due to its lack of optimization options. Using PDf 2 cad allows me to create many different formats of drawing quickly using some simple tools. It has a wide range of features and it is very easy to use for those who don't have much experience using cad software. I like how you can edit your designs at any time and make changes as needed. The program isn’t perfect, but we are working to improve it. With a little training, it's easy to learn how to use and edit CAD drawings. We're creating 3D models for our clients and this allows us to create them without having to send them out to another vendor.
