parameters in mechanism connections do not update?

For example:

Ive created a cylinder assembly of which all relevant dimensions are driven by a list of parameters.

Whenever I create a copy of the cilinder with new dimensions, The max extension of the rod is also parameter driven and should therefore also update when I change this length. Sadly this does not work. I can fill in the parameter (in this case: "SLAG" pardon my Dutch) and the parameter changes into the number, but will not update after.

 

Any ideas?

That's correct suggestion Martin.

Any connection related constants are represented as "connection parameters" :. For Pin rotation axis for e.g. we have :

ROTATION1_STATIC_FRICTION

ROTATION1_KINETIC_FRICTION

ROTATION1_CONTACT_RADIUS

ROTATION1_RESTITUTION

ROTATION1_MINIMUM_LIMIT

ROTATION1_MAXIMUM_LIMIT

ROTATION1_ZERO_POSITION

So to drive connection parameter by any model parameter it will be best to create component level relation, like :

ROTATION1_ZERO_POSITION:CONN_2 = ZERO_POS_PARAM

where correct connection postfix (CONN_2) is obtained automatically when you select parameter in Relations / Insert Parameter from Name List / (select Connection subtype) / pick corresponding connection in Model Tree.

Hi,

I guess that you have to define a relation, which puts model parameter value into mechanism maximum limit. Unfortunatelly I am not sure if it is possible to define such relation.

Cheers Vladimir,

Works like a charm.
