Is there any way to place few objects on a curve with equal distances one from another? I tested it yesterday:

1. Drew NURBS curve with 5 CV's to form it
2. Resample SOP with 10 points
3. Box SOP
4. Copy SOP with curve and box plugged in.

Well, i've got a curve with boxes on it. But these boxes wasn't aligned with curve. I tried to add Point SOP with “Add Normal” option, but no luck. Any ideas?

Sounds like the objecs you are copying are not at their origins.

First make sure that all the objects are originally oriented so that their origin is the point where you want the object to be placed with the copy SOP on the curve. The offsets of each object from the origin is used by default with the Copy SOP.
