No shooting this stuff is more pain than pay. Its also very hard to explain to a manufacturers mentality about good imagery, when all they do is think how many pieces they can stuff in one shot.
But those are the newbies who have no clue about marketing. I stopped being an educator, so I don't do these types of shoots much any more.
You likely use Solidworks and Matrix, Rhino etc. good stuff. You can create images from those files too. That last one, left stud can be better positioned, but it is nice. (When I say better, I mean I might have positioned it differently:-). It looks great.)
