Actually, you’ve tackled a very important question here.
What do architects use apps the like of ACAD or Revit for and what do apps like SUp do?
There are two very distinct tasks in our pipeline. Well - in mine anyway, and has been like that for 20 years now.
1 - The sketching phase
2 - The drafting phase
Simply put - SUp - 1, CAD - 2
1 - Fast, natural navigating in viewport, fast basic geometry input / editing with basic 3D snap, basic boolean operations, nimble and forgiving scaling feature, a couple of basic materials, simplified UI, quick shadow cast, section boxes, nimble camera creation / trans-positioning, neutral / precise / un-binding aesthetic style. Sounds familiar?
2 - You know the lot - Broad spectre of geometry generation, robust / versatile / precise snap, powerful and robust dimensioning system, possible BIM element creation and parametric capabilities, automated / manual drafting capabilities etc.
You can’t sketch with number 2 and you can’t build with number 1.
Now - can these be united with good quality in one app… not sure…
Should they be… possibly…
Do we have a good chance - judging by the authors of Blender, FreeCAD and BlenderBIM - yes.
Great development initiative aside, and not implying BlenderBIM has this in it’s intended scope, but what i (and possibly other arch enthusiasts) still don’t see here is some concrete protocol for pipeline number 1. The important one.
How do we make a sketch of a house here?
