For 2D work consider Corel Draw, surprisningly, and Autotcad or TurboCad.
For 3D work Rhino cad or Solidworks.
Most of the people on RCgroups are using one of these four.
None are easy and intuitive to drive!
If you are a skilled hand drauhgtsperson, Corel will come fairly
naturally: If not the CAD programs take a slightly different
approach,which others find easier.
