Could there be a 3D modeller that can generate a 3D model from a blueprint or reference image where the blueprint shows at least two different perspectives of the object, so the modeller uses some technique like starting with a rough shaped mesh and projecting the blueprint background co-ordinated to 3d co-ordinates and shaping the mesh to the blueprint shape like a dough ? Or starting with a flat shape and extruding while shaping it to the blueprint's shape? I could have created a Blender script for this if I had time.

  • It is common for people to use blueprints or reference images as a guide to get proportions right as they model or sculpt, but don't expect that to be automated. Photogrammetry is the process of taking multiple photos from different angles to generate a 3d model, it needs more than three views from a blueprint. – sambler Sep 23 '18 at 6:01
  • First of all, this question seem a bit off topic here. — Maybe you've seen this, since it is shared online every now and then, but this a pretty solid real world example of photogrammetry youtu.be/eXMJr-aB4qw I thought I'd share it since it's pretty cool. — What you are asking about is too much. I definitely don't know anything about this, but I feel like you need like an AI to do what you want. AI assisted design does exist but this seems a bit too much. You may have to invest millions to Autodesk to pursue this further. – Joonas Sep 23 '18 at 19:34
  • Yes... AutoCad (or other CAD programs)... But you need to draw the blueprint and the orthogonal view on... Autocad (or other CAD programs) – Rafael Sep 25 '18 at 16:40
  • But also you are confusing Blueprints to perspectives. – Rafael Sep 25 '18 at 16:41
  • Or do you want an AI driven modeler, so advanced that could see a sketch on a napkin and a perspective from the other side? Even humans struggle with that. When we get there... we are in trouble. – Rafael Sep 25 '18 at 16:44

I myself do exactly this sort of thing for clients as an architectural designer, 3D modeler and renderer quite quickly and efficiently, in a toolset I've developed over the years (using either ArchiCAD or modo depending upon client and project needs) but based on the huge variability of plans I see, I'd really have trouble imagining a fully-automated process or tool that would have the range of responses necessary to work in the real-world... even within a single firm, there tends to be a lot of deviation from the firm's published CAD or BIM standards, and though many US firms will tell you they use or follow the National CAD Standards very few do in fact follow them - it'd be more true to say they use them as a baseline for their own adapted version specific to their client-base, use-case and project mix.

As a result, if you wrote a scripted system to derive walls from lines of type X on layer Y - it'd fail in 80% of files imported.

I use the client-provided CAD as a reference and snapping base - and if I only get scanned images of the plans, I can effectively do the same.
