Animating Constraints - Specified value could not be applied??

[brianmcmeel]

Hi. I've got a fairly complex assembly in Inventor 2013 with a number of drive constraints set up, which I can drive in the assembly but not in inventor studio... there don't appear to be any conflicting constraints in the assembly and I can't figure out what the problem is.... Any suggestions or help appreciated.  I'm not sure what files in what format to attach here so if someone can help with that also.  Thanks.

You would need to attach the primary IAM file and all related files. Use the Pack & Go to a single directory would be the easiest method. You would then need to open each IAM and the move the EOP marker to the top of the directory tree. This compacts the size of the file.

Thanks for replying Blair but i'm not sure how to do what you suggest...

Open your Windows Explorer, navigate to the top level IAM file (your main assemble) RMB click on the file: you should be able to see the "Pack and Go" in the pop-up-box. The rest is pretty much self explanatory, save copies of the files to a separate directory. It makes it easier to find after and keeps clutter from your primary work directories.

I usually have a "Temp" directory on my main hard-drive just for stuff like this.

In my experience this is normally due to a conflicting constraint. Expanding all your assemblies and looking for any warnings or over constrained parts will normally solve this problem.

Just spent a few hours in studio getting the same error message.

This was despite being able to drive the constraint successfully from the browser.

When in Studio and trying to animate the same constaint it failed.

After seeing this answer I went through the assembly resolving and deleting unresolved constraints until there were all cleared.

This solved the problem and animate constrints now works.

Hope this helps.

Worked for me! Thanks a million!

IMO this is not solved yet.

See video in attachment.

Oh, I beg your pardon. It's been me.

I used two point-to-point constraints. That's working only with linear path.

With a curved path, a point-to-point at the leader and a point-to-axis at the follower must be set.

[WHolzwarth]

Well, it's not only me. See another video.

Nice animations could be possible with Studio - but it's not reliable.

Thank You. I T   W O R K E D. There really was a constraint with warning sign. I spent many hours reading help and "hitting my head on wood". Yours Sincerely, Leo Kiviluoma
