I already know that what I'm asking is probably no longer considered the 'best' way - but I just want to know if I 'can' - or if I'm just wasting my time trying to find a way. To repeat, I want to create a 'part' or '3D image" by FIRST creating a properly dimension-ed 2D front, top, and side view drawing - just like the old days and convert 'that' to 3D perspective - NOT create a 2D drawing from an an imported and/or already created 3d part/image like shown in literally every tutorial I've run across.
I may have mentioned it here in the past, it so happens that more than 10 years ago, in my search for a CAD program that ran on Linux, I stumbled upon a program that does exactly what you are asking. It still exists, it's called MEDUSA4, there's a free "Personal" version. although they only have a Windows version now:
It had a really nice set of 2D drafting tools, but I couldn't get around the whole 2D drawing to 3D thingy, it felt so weird. Also, two big turndoffs were that the 3D model was only a preview, you couldn't export it; the software had its own custom file extension, you had to pay to export to DXF or PDF, those were the only possible file formats. The closed system didn't sit well with me.

That is pretty much impossible, however in a simplistic sense, for simple cases, that is what Sketcher does in PartDesign WB. Create a fully constrained 2d sketch then "Pad" that to a solid.
As I showed above, it may not be currently possible in FreeCAD, but it could be implemented in some capacity, if someone was willing to develop it.
Without going as far, some kind of wizard could be programmed (even a Python macro) to facilitate this. Solid Edge (commercial CAD program which I've been using for work for the past 12 years) was pushing a lot for this 2D to 3D transition. See an old video here:
I haven't seen them advertise this process much lately. To be blunt, who's still working only in 2D? I would say that most "old timers" have retired.
I lived through the transition from the drawing board to the CAD computer while I got my degree and that was quite a long time ago. Mid-range parametric CAD systems have been around for 20 years, high-end systems longer than that. I believe nowadays students go straight to 3D and never learn to create 2D blueprints.
