Rotate Assembly Part

Anonymous — Mon, 06 Mar 2017 20:35:47 GMT

Hi! New guy question. I am working through a tutorial and I when I am constraining the two pieces of this vice the clamp DPV_6S_02.ipt should have the hole facing away from the vice grip body DPV_6S_01. I am thinking I am screwing it up when I am selecting planes maybe. Any advice for how to rotate a part in an assembly along an axis? I am sure it is probably something simple I am missing. Thanks!

Without looking at the tutorial, you depending on how the work planes were set up, you can use either the Mate or Flush. Work Planes have a Top and Bottom side. The Top is the Tan color while the Bottom is the darker blue-ish color. So if you use the Flush constraint the same color will be in the same Plane for both Work Planes. If you use the Mate constrain the Same color will face each other.

Hi,

Thank you for posting your question. Please check out my video, it quickly explains how to constain.

If ever you want to quickly rotate things such that they will do more áutomatically'correct when constraining use 'Assembly --> Free move'

Also, realize that you can constrain 2 parts as Mates: 2 opposing sides, or flush: 2 sides facing in the same direction. You see mee messing with the two here.

Finally, when you use less that 3 constraints, it is not completely restrained in space and hence more solutions (backward, forward facing for example) are possible and Inventor can show either one to you. Just always fully constrain

That was amazingly helpful and easy to follow! Thanks so much! One thing
I notice now however is the part no longer moves along the tracks.

Hi,

That's correct! When constraining you often constrain something to a fixed point, but that's not always desireable.

Now go back to your Flush constraint and add limits to your motion:

Now it can move between 0 and 20 inches measured from the face you contrained on.

As 20 is too much you must find out how much is the max. You can measure this, or dynamically determine using 'drive' which animates the limits you set:
