Hi All,

I'm trying to perform a relatively basic operation within a part - an equally spaced pattern of a body along a helix using the 'curve driven pattern' feature.

The helix has a revolution of 0.5 (180degs) and the body to be patterned is a 45degree revolve, with 4 instances, so should exactly line up to the helix in plan (with 'equal spacing' checked).

However the result I get is out, by a significant fraction (see attachment). Anyone else had this problem? feels like ive been here before...

best
