I like that it's very intuitive and easy to learn for people who are not familiar with CAD software. It's a little pricey but you can do so much with it. I also really like that it has a lot of different options for using as a 3d modelling program as well as being able to render images in photorealistic quality. If you want to use it as a design program, then it would be nice if there was an option to import other file formats such as.stl or.obj which would make things easier if you wanted to create models outside of modo. You can also import a 3d model into modo and work on the design. I can also export my designs for use in other programs such as blender, etc.
