I just thought I'd put this up for those who may want it.
I'm currently working (in my spare time) on drawing up an accurate Subaru 4cyl engine model for my aircraft designs 'cos I'm picky and I do like things to look right even on paper (CRT?).
If anyone wants a copy of the finished file I can send it to them in most 3D formats, and I might even be able to make a passable 2D version as well from the finished item
I expect to be finished it sometime in the coming week.
