solid interference problem

[euGENIO85]

Hello everyone, I am new to the forum, my name is eugenio and I am a student graduating from ing. mecc. at the University of Catania.
Now let's go to the problem.
I am using inventor, I have both the 2008 and 2010 version (although in English :frown, I have to play in 3d a rov (i.e. a submarine robot). the problem is that in the assemblies, I cannot fail to connect two solids (or, in general, to set a range within which you can move a solid ab). e.g., if I have a cylinder and a piston, giving the concentric bond I can align the piston to the cylinder, but dragging the piston, this does not stop at the end of the cylinder (no on the closed side or in the open side). How do I solve the problem?
with solidworks I could bypass this problem by setting the bond with a range of two values, can't you do with inventor?
Thank you all.

you have to activate the "resolute contacts" (under analysis), then right click on the parts that interest you and choose "contact group". use it only when necessary because it weighs everything down.

Thanks endlessly, it's already something, I don't like to see the parts that intersect. . .
but instead it is not possible to make constraints between a range?

No.
in some cases it can be an alternative solution the use of the transient bond that guarantees the contact between two faces, like in a cam-disk system.

Maybe I can interpret your need and give you a little orientation.
if your need is to study the kinematics of a mechanical structure having some degrees of freedom, you can animate the constraints by assigning an initial and final value to the movement (translation and/or translation).
You can also relate different constraints through a mathematical relationship that binds movement (animation) of a bond to that of other structure constraints.
go then on the browser choose the constraint and click on soul constraints (right mouse button).
to view an application I send you the link to an animation that I published on youtube: study of a manta-shaped rov -http://www.youtube.com/watch?v=hhyc1rppyb8
or other animations of other structures

in 2011 you can give a range to the share of a bond.

@donatomazzei
to what I understand what you say would be done in animation. I solved the problem by creating auctions that limited the movement of moving parts and then removing their visibility. a somewhat laborious but effective solution!

in 2011 you can give a range to the share of a bond.

I want it. That's exactly what I needed!

you can download a 2011 educational license from the autodesk student sitehttp://students.autodesk.com/your university will already be enrolled and through an invitation that will have to be sent to you by the teacher responsible (or with other methods put in place by your university) you can register to the site and download licenses and/or software of the autodesk house including inventor 2011 ( validity one year):smile:
many technical institutes are also enrolled. The total number of members of the site (students, teachers) is about 1.300.000.Real an invitation, by e-mail you will need to click on the link and follow the instructions, you will receive passwords and login accounts.
you can also share drawings and communicate with other users(in English)
