I'm trying to convince a colleague of mine to switch from AutoCAD LT to Blender for structural drafting purposes. Even though Blender was not originally designed for 2D operation, it has the advantages of A: being free (as opposed to $1000+) and, B: having a lot of potentially time-saving functionality (the loop-cut operation alone could probably cut 5% off of drafting time, not to mention the array/mirror modifiers, etc).
However, my friend does not need most of Blender's 3D functionality, since structural drafting is almost exclusively done in 2D. In the best case scenario, I could configure him a stripped-down copy of Blender with all the exclusively 3D operations and hotkeys hidden, as well as rendering/materials/physics/etc. At the very least, I would like to configure Blender so that it is locked into orthographic top-view. How would I go about accomplishing either of these?
