New for Autodesk Inventor 2011 - Constraint Limits

Check out more here www.ketiv.com/blog
In the past, when we've wanted to limit the range of motion for an assembly, we had Positional Representations, and Contact Sets to fill that roll.
Both tools work great, I use them, and I'll continue to use them in the future. For example, using the cylinder assembly below as an example.

Postional Representations are great for creating an 'extended or retracted' scenario, they couldn't let the assembly move between those extremes. Positional Representations can create snapshots in the motion.
Contact Sets, on the other hand, could allow an assembly to move between two positions, but the parts have to physically contact each other. So in our example, the piston inside the cylinder would have to hit the endcaps to stop. This might not be good for the life of the piston.
But now we have Constraint Limits! These set the limits on a constraint offset so the piston moves through it's motion, but I can define the offset in such away that piston doesn't hit the endcaps.
So far, this is sizing up to be one of my favorite Inventor 2011 features!
Happy Inventing!

Thanks. My apologies for the breathing part. I've been working on it, and improving, but it's that last little 'bug' I'm trying to get myself past! Mostly trying some different audio and mic settings\positions..

[@zackdattacker]

thank you sooo much! this video was so helpful! I didnt know how to do this at all for years!

[@Craigthepope]

Thanks, this was really helpful.

[@PHY104]

Thank you so much! you saved my project!!

[@TheHAHAHAperson]

How do you do this for something for a door hinge, where it needs the degrees... :/

[@KETIVTechnologies]

Check the manufacturing section the KETIV website there's a link to download the file in the tech tip section.

[@WeslieJJ94]

Where can I download Inventor ? Really need it !

[@phitrantruong3125]

thank man, i love science and i love you too

Hi,
We are so glad to hear that! For more resources, don't forget to visit our website and check our our Autodesk Virtual Academy page here: ketiv.com/academy/

I'm afraid there isn't a way to downgrade the files in such a way that you can see the features. You could export step files, but no features will come across.
One other thought, (although a bit MacGyver), would be to export a step file from 2011, open it in 2010, and use the feature recognition tools off of Autodesk Labs to recognize the tools.
That does assume school lets yo do that! :-/
Hope this helps!

@WITEAFRICAN I think you can't do that. Atleast there wasnt any way few years back.

These constraints are not available for animation. I personally experienced with this type of constraints
