Lots of modestly experienced and self taught manual machinists in the
maker crowd use layout as a sanity check.

----------------------------------------
That makes sense if they are primarily a designer rather than a machinist. I 
was formally an electronic technician and laboratory manager, with circuit 
design, CAD/CAM, programming and machining on the side. I've done more 
machining on home projects than for work.

If the function of a part is obvious to me I'll draw it with dimensions and 
follow them, when it has multiple interactions to coordinate I may 
alternately redesign and machine what I'm sure of. I have several 
preliminary versions of the satellite laser link hardware that separately 
addressed its mechanical, electrical or optical requirements. Since I didn't 
have a relevant engineering degree I was much more convincing when I showed 
them a neatly machined sample of what I intended than when I described or 
sketched it. The project manager brought me in as an electronic tech and 
then gave me a free hand when he found I could also create hardware to his 
specs. One engineer said my black-painted optical work looked like the parts 
of a Norden bombsight.
