Issue:
You want to setup your Inventor assembly so that parts will not pass through each other in an unrealistic manner.
Solution:
Add components to a Contact Set and then use the Contact Solver tool to allow Inventor to solve for contact. See video for how the tools work.
Note: It’s best to disable this feature when not specifically testing part contact, as it may impact performance in a negative way as Inventor attempts to solve contact relationships as you drag parts around in typical constraint and assembly tasks.
