Problem with curve driven pattern

Hi

I am using curve driven pattern to draw a chain for a manure spreader. After drawing two chain links i use curve driven pattern to draw the rest of the chain links.

First i click on the line for the pattern direction, then in "features to pattern" i select the chain link i want to multiply and choose the amount of chain links i need to get the chain i want. When i press on OK the chain links does not appear. But they did appear in yellow lines in the feature manager.

I will upload the drawing i am talking about.

Thank you

Tom Van Daele
