I will recommend via cad pro 8, or viacad 2d/3d form punchcad, I am a intensive SharkFX user and it is the whole complete package, i use moi for modeling some surfacing where is much better then shark, and also flow command.

shark-viacad are still buggy and have many glitches, but it worth for the price and all the features that include, for 2d sketches, the model to sheet feature is very good, just stay very organized and you are done.
