The base extrude sketch for the mounting plate locates the CIM nub. That includes the +0.003 PD increase for gear mesh. That sketch is built off tangent circles inline. That sketch locates the center for the bearing holes, idler gear, and CIM nub. There is a +0.005 for CIM mounting (it takes into account powder coating). The second extrude cut on the main CIM mounting plate locates the CIM mounting holes at a 2in C-C off of the nub location.
Is there a better way to do this? I am self taught at Solidworks and I may not know the most efficient way to do something, but I can definitely manage sketches, circles and lines!
