Constraints in Inventor vs MDT

[wendert]

In MDT I was able to constrain 2 models together while constructing them by selecting specific points on the models to form mid planes which allowed me to constrain them together while actual building the parts. Once I had holes or other real features to constrain the model to, I would eliminate the constraints I had temporarily made, and I would simply add the new constraints. Inventor does not appear to do this. I have not had a training class...yet. Do I have to actually build a plane on the part? Also, In MDT I never worried about where I drew my part in space. Someone indicated to me that you need to pay attention while using Inventor. Is this true?

You don't need to worry about where you build your model in space, but it can simplify and reduce problems if you build parts about the origin. Look into skeletal modelling (I can't explain it).

you're referring, i believe, to the "intelli-constraints" that MDT had which many users miss... unfortunatly inventor doesn't have a feature which does this so i understand your pain.

however, you may like to look into skeletal modeling, which i absolutely swear by. start here (

and come back with questions if you have any.

also, inventor can constrain to a few things MDT couldn't, such as sketch geometry. i often use sketch geometry to help me constrain things, if i'm not using a skeletal method.

Thnak you. I will go through the skeletal exercise today.
