inversion constraints

[INVENTORMUSTDIE]

Hello.
I am using inventor 2014 and working with positions representations to create motion sequences of the machines I am drawing to then create a small video with inventor studio. In practice I have the problem that often and willingly the program reverses the sign of angular constraints (inverting the orientation of the element) passing from one representation to another, even when it creates animation with inventor study. even the cylinders that bind only axially to allow a scroll, when I step from one representation to another I find the stem that goes from the opposite one without a precise logic... Does anyone know any tricks to solve the problem?

try to use the angled alley with the "express reference vector", is the third right icon in the constraints window.

 

[essebi]

as regards the stems, use the pin/hole constraint with the maximum and minimum option

Thank you, the first solution I have already tried and it seems to work, I will also try for the stems...

Dear friends... I connect to this forum to explain my problem:
in the cylinders that I downloaded in my business folder I put the constraint on the stem with race limits (0-200mm) for example.
When I insert the cylinder into a set, and I make it flexible, at a certain point the bond with limits (which is inside the cylinder axieme and not in the machine) gives me error and turns on the annoying red cross.
if I open the commercial cylinder with another project, the bond is correct.
keep in mind that the movement of the machine works, but the message of incompatibility of the constraints does not turn out.. .
Does it happen to you?I hope I've been clear... and thank you for your help.. .

Yes, every now and then he decides to report error in the flexible bond, and opening the assembling and closing the error disappears, never understood what it depends on...... .

same thing to me too

... and when he starts doing this, there's no way out.
with the commercials I can also understand it, sometimes the models are made with the feet, the fact is that it also happens with my models, which are made with maniacal care.

I'm the only one with commercials. . .
but it is known that it only happens with the trade movements with the limit.. .
when for example in the cylinders I had only the stem with the constraint coincidence on the axis without limits in the race, all this did not happen.. .
the only mole is that you had to be careful not to pass the races of the cylinders and you had to check them from time to time.. .
Good job!
