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!
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.
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.
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.
I have the same problem. And as rjezuit says, try to ungound your parts. Every assembly should have only one part grounded no more than that. Another thing that could be causing this are adaptive sketches and parts. You should always turn the adaptivity off.
.... Every assembly should have only one part grounded no more than that.
I often have multiple grounded components (parts or sub-assemblies) within my assemblies.
Well that's what we were told by Autodesk employees. I must say that it makes my life much easier because assemblies with high number of grounded parts don't tent to behave as they should....
