Inventor 2014 takes too long to think placing a constrain

[Hfrossard]

I have been running Inventor 2014 on my machine for a while now. I don't know what is happening, but it takes about 5 minutes to think about a constrain placement.

It was not happenning before, I think some kind of update triggered this.

What should I do?

My guess is that you have something wrong with one of your parts or with one of you existing assembly constraints.

Are you using Adaptivity?

Can you attach your assembly here?

[Hfrossard]

Unfortunatelly I cannot post the assembly due to product secrecy agreement. 

There is no adaptivity. 

It may be some constrain problem. I have a big assembly with lots of sub-assemblies. 

[howardlee306]

Check to see if constrain failure redundancy analysis got turned on during the update.

[blair]

Inventor does have a "Show Sick Constraints" tool. It's in the Assembly Tab under Relationships.

[Hfrossard]

Thank you for the replies.

The redudancy check was on. I turned it off, it made the constrain placement a little bit faster, but it is still taking a lot of time.

The "show shick constrain" button is grey, so there is no bad constrain anymore, I think.

A new problem is that, from time to time, some sketches (used to build the parts) started crashing and losing their references. In most of them, if I redefine the face to the same face it was drawn on in the first place, it works.

That would be adaptivity of some form and would cause a big assembly to slow way down, especially if those sketches kee losing their references.

[Hfrossard]

What is the best way to find and resolve these adaptivity issues?

[blair · Accepted solution]

I try and clear Adaptivity as soon as possibly in a design. It will require going back in to sub assemblies and applying additional constraints once the Adaptivity is cleared. No really "Easy Button" to fix it. Having a number of items "Adaptive" will slow down the fastest of systems.

[Hfrossard]

Thank you very much. Now I see that there are a lot of adaptive parts. I am clearying all up.
