But generally, wall thicknesses are not arbitrary. For example, an
internal wall is going to be constructed on 2x4 framing. With an
architectural CAD program, one click would increase that to 2x6
if, say, you decided you wanted a pocket door. Likewise if you
wanted more insulation or stiffness in a particular exterior wall.

But those artifacts correspond with the in-built preferences of the
CAD program. Many of the dimensions you mention aren't as arbitrary
as they might appear once you consider the consequences; door and
window sizes, ceiling heights, etc.

But a solution depends on how much help with designing is needed, and
how much is just drafting.
