Hi, I have been building an assembly and suddenly I am unable to move parts according to their constraints. I can move them as soon as they are placed but as soon as I add one constraint it's as if they are glued in place. For example, when I line up two holes I can no longer rotate one part around the grounded component.

Have a turned off some functionality of the program?

Any help would be much appreciated!

I'm having this same problem, hopefully there is an easy quick fix.

There should be quite a few threads in this forum over the last several years that discuss this problem.  Unfortunately there is no quick fix-- it seems that Inventor can get confused in certain assemblies, and there is no solution other than deleting a bunch of constraints and starting over.  But do some searching and see if there's any more guidance from people with the benefit of experience.

Look for a bad constraint, this seems to freeze parts, also having a second part selected in the browser will do the same thing as well.

do as the others have suggested, but just to get you out of trouble if it needs to go out the door...

Although you can not drag the component, you may be able to move it by adding additional constraints, just add them as you would normally would and see if it moves correctly

Hi Ben,

Could you attach your assembly? If you have some simple assembly that exhibits the problem I can take a look closer for source of the problem.

Thank you,

I have had this issue also, in 2010, 2011, and 2012.  It seems to be related to previously placed parts that are grounded. If I "un ground" parts placed before the one that is messed up it seems to free them up. Then I ground the previously un grounded parts.
