Assembly Constraints Greyed out. V5 R19

[si894]

Hi,

I'm trying to assemble some basic parts inside of a product but for some reason the only assembly constraint available to me is "Fix". All others are greyed out. I've never come across this before and can't figure out how to solve it.

Any ideas?

Also I have just noticed that Prducts I havee created at an earlier date have the constraints available to me. It just seems to be anything new I try to create. Have I switched something off somewhere?

Simon,

Some parts might be grayed out because their geometric features are not available to use for constraints. Try double-clicking on the Assembly name (top of tree) which should change the representation from Visualization mode to Design mode.
