Any help on how I could accomplish this would be greatly appreciated. Im new to macros, and know Im likely headed on the wrong track.

I am trying to create a macro that would import a part to make a set of cylindrical cutting heads. I have a design table set up in a part file to save individual configurations of cutters/spacers. 

I would like to open my selected part config in an assembly, create a sketch for the center to center distance of my axles( to later drive that dimension in a design table), from there it should be possible to automate

• create a linear array (with rotation about the center axis) 
• then mirror(copy) and flip that part. (with center at sketch's "center_to_center")
• set mates for faces of the two parts and their center locations based on sketch
• finally create a design table (which I will populate manually after automation)

 Ive been trying to record the macro but havnt had much luck getting any of the above goals to register. I am open to any new ideas. 

Thanks,

Aaron

included is a test assembly for what im trying to accomplish.
