Hello

I am have a problem using the Curve Driven Pattern feature.

When I try patterning the desired features (see attached file) it gives me this error:

"The selected features could not be patterned using a geometry pattern, deselect the geometry pattern check box"

When I do as it says, it gives me this error:

"Invalid feature for patterning"

I'm wondering what I did wrong and would greatly appreciate it if someone could help me out.
