constraints

[fiorot.daniele]

and here I am to disturb you all for the new enigma:frown:
I'm supposed to bind a collar to a calandered tube... I press that when I used solidworks I created a pilot sketch in the parts and gave the coincidence with it but with inventor I can not do it.
in the sense I create them sketches but I can't use them in the mating stage you know give me some suggestions place a photoI hope it is quite clear

have you tried with the transient bond (maybe between two pilot surfaces as you did before)?http://help.autodesk.com/view/invntor/2016/ita/?guid=guid-ede88086-58f3-4f62-a1cc-83cdb035bc27

ciao

hello first of all thanks to the cmq response the transient does not go because rightly I try to run a cylinder on a sweep
The problem is I don't understand an inventor thing... If you could have the problem solved, but on the guides I can't understand this... all the work is based on this win.
I understand that my constraint is a bit strange because if we want to analyze it is an approsimation we say that mechanically it does not exist but in reality it is fundamental to me.
to make you the idea imagined a greenhouse with the curved helmet made of 60x2 mobile tube with these collars as in photo that serve to support the internal traliccio.
I hope it is clear help!

I honestly don't understand what you want to get.
do you want the clamp to be tied to the profile of the tubular and that will run along the path?
Do you have to make a dynamic and/or filmed test with a change of geometries?
because for a static assembly I do not see the difficulty of making a concentric bond.

Sorry but sometimes it is not easy to explain
cmq in the meantime I solved and since maybe someone falls into my problem place my solution

inside the collar I created a tangent plan to the inner throat of it
then in the axieme I made the y/z plans of the two parts coincide, then I put the tangency bond between the plan created inside the glue and the curved part of the pole.
the result is that the collar flows me freely on the curve maintaining a concentricity with respect to the tube
