is it better to model houses and buildings with CAD than with subdivision techniques?
depends on the project
How do I scale something only on X axis in Autocad?
>install blender
>sx for global x, sxx for local
Shut up, Andrew.

>Pick point
>Hit "R" for reference
>Pick again same point as you did first
>Pick second point
>Scale it
If you are designing something to be built by others and to be assembled by more than a rapid prototyping or CAM process, then CAD.

If it's purely digital or fabricated by 3D printer, then subdivision techniques are fine.
I work with solids for cad and never once touched a subdivision unless I'm working on an organic model, but then I won't be doing solids in the first place.
what are solids anyway and what differs them from subdivision? I keep hearing this term here and there

Seriously, how to scale in one axis only?
A solid is a parametric surface, more similar to what you might think of as a spline or nurbs, rather than vertices or edges of a polygon. Unlike a polygon that's simply built up of fixed, defined points in space, solids are instead built using "rules" for how they're supposed to be drawn, and as a result, solids don't inherently have any topology.
A solid defined as a sphere is always going to be a mathematically perfect sphere, but the representation of that shape might be more crude on account of your GPU being able to only render triangulated polygonal objects, it's as soon as you render it or send it to be printed or cnc'd, that the shape will be perfectly smooth to within a fraction of a millimeter.
so it's sort of PBR in modeling?
