I would like to see Plans and Elevations drawn in 6:30 let alone 3:30, the only way is to have like Revit,Architecture or another 3rd party program, still no way 3:30 = a box with a roof. It takes more than 3 minutes just to think about it.
My attempt with Cadarc.

The time includes a initial setup of wall sizes etc the windows sizes are entered by the user, the object is full 3d with a whole cut through wall for window.
Ps forgot this could be done in LT but very slow as there is no 3d solids a step by step process.
