Why can I not constrain placed objects with three constraints? Anything I place constrains with one constraint then is virtually fixed (without being) and cannot even be moved to allow for further constraining.

Solved! by nickhowe. See the answer in context.
It looks that way! No reasons for why it doesn't move manually?
any grounded parts?
any imported parts?
No grounded parts or imprts just a placed assembly that "grounds" on the first constraint.
Since then I have found that i can still add constraints. I can't physically move it after the first constraint but can move it via the addition of other constraints!
Thanks for the help, think i'll just file this under weird!
I've had that happen to me before. It's like certain parts/assemblies piss Inventor off. Usually I find sick mates or featues in the problem component. I find that using the move command instead of just dragging works fine.
I am having this same problem with a certain assembly. It has many parts that have already been fully or partially constrained. Everything that has at least one constraint on it appears fixed even if it had been "movable" earlier. I can't post the file as it is proprietary but wanted to check and see if this was ever truly solved.
Are there sick mates anywhere in the assembly? Are there any sick features on the parts in question? Are any of the parts in interference with each other?
No, no, and no it seems. The parts move normally if they have no constraints but as soon as you add one constraint (even if its to a part that previously had no constraints as well), the parts are "fixed." I can still add more constraints and get it to align somewhere else that way though.
I have "Updated" the whole assembly and tried "Rebuild All" and still have the same problem. This is the first time this is happening with this assembly as I have been working with it for about a week. I don't know what has changed.
