I am a Day One Babe in the Woods to this stuff.

I'm trying to build a copy of an intake manifold, piping, and supercharger brackets for a V8 engine.

The parts are simple. Cylindrers, orthogonal blocks, perpendicular holes, etc. where an accuracy of 1/8" would be fine. 3/16" possibly acceptable, and 1/4" excessive.

I saw most of the discussion was regarding "scanning" which involves measurement devices, some hand held and others with a fixed scanning region. Lasers sound common with this equipment.

But no mention of using multiple pics to build a 3D shape.

QUESTION #1: What is the proper terminology to refer to "building a 3D shape with multiple pictures?" I'm guess it is not "scanning."

QUESTION #2: To get help with this method, what forum/subforum should I go to?

QUESTION #3: What are recommended products? Obviously, keeping costs to an absolute minimum are a constraint.

Thanks in advance,
Tom
