I'm designing a 9 cylinder radial with PRO/E Wildfire, just to get familiar with software. No plans to take it beyond model stage, but I want to get it technically corect. I have been searching for a good cutaway or graphic showing the cam drive, but have not found anything yet. Can anyone point me towards a good reference that shows the layout of a nice clean sesign? I know what i want to do...firing order 1-3-5-7-9-2-4-6-8 with a cam ring but my thick skull just won't come up with what I want.

Thanks,
