I borrowed a fan from 3DW and made some revisions but when I came to adding the rivets they’re just all over the place. Tried a circular array but arms aren’t rotated evenly so rotated group of rivets manually to each arm but have same problem. As I move rivets from arm to arm they appear to be changing position radially on each blade as well as receding thru the arms until by the 4th or 5th arm they hardly show on the front surface anymore.
I rotate about the origin out to a similar point on each arm. I rotated all the blades around in a similar fashion and all attached to surface of each arm the same and appear identical so can’t figure out why the rivets behave differently.
Rivet placement doesn’t have to be exact. The position of four rivets shown are close enough if they appear on other blades in similar position.
