This seems to be a straight forward operation, but it's just not working in WF5. I created an extrusion and round, move copied it, then axis patterned the moved surface. I'm able to merge the extruded rivit with the wheel, but when I try to do an axis pattern of the merge it fails; no matter which object I select first. I've tried patterning individual features and groups, but the merge always fails.
The wheel spoke seen in the images were constructed the same way, and worked without any problem.
Could this be a bug with the software, or am I missing something here? Trying to merge every instences of the pattern is just way too time consuming.
