Perimeter constraint in a sketch

Out of category

Hi all

I'm in the process of designing a belt sander. To define the general geometry of the machine, I need to position 4 rolls of known diameter with the constraint that the total perimeter of the curve stretched on the 4 rolls is the length of my belt, 1829mm in this case.

Do you know if there is a constraint mode that can freeze this total length of the line so that the position of the last roll is automatically set according to the position of the other 3?

I think this is the same type of stress that you encounter when designing a system with pulleys and belts.

A big thank you in advance,

Yes via chain belt tool you have a properties tab with to check length of runner

Basically, it's more in the assembly than in the sketch.

In sketch you have a dimension that we saw not long ago which allows you to have the value / length of the track but does not allow you to steer visibly.
