FYI. I did purchase CAD Lite and so far it is doing everything I need. I have been able to insert a jpg, use Civil 3D files and open documents that I receive from survey and engineering firms. I am working as an independent designer. I did not learn the 3D function on CAD and use Sketch Up if I need a model. I’m sure this is not as efficient, but for the price and the frequency with which I use it, it is fine.
