Problem with flexible parameters in assembly

Hi,

I can't find out what am I doing wrong with my chain assembly model.

End links and main links are assembled with MDX assembly constraints and flexible dimensions.

At assembly level, all these dimensions are controlled by relations and parameters.

And these parameters are declared flexible in the chain assembly model.

Up to this point everything works fine : when I change parameters, everything regenerate as expected in the chain assembly model.

When I integrate this chain in another empty assembly, the first link of the chain does not regenerate correctly when I change the flexible parameters. All others will regenerate as expected.

I don't get why.

Any hint ?

With the help of many posts in different discussions, I finally found a way to set my chain correctly :

In short, I added "associate parameters" to all the varied dimension of the individuals links so that I can call them in the relations.

I don't understand why but in relations at assembly level, calling the varied dimension with the parameter (w01:FID_74=width_main_link) works fine but calling the same dimension with the varied dimension (d0:6=width_main_link) leads to problems at a higher level assembly.

With this set up, I can assemble as many chains as necessary, all with different dimensions in a top level assembly and it works fine every time.

so I am done for what I wanted to do, even if I still don't really understand why it works now ...

If anybody knows I would be glad to hear.

There is nothing immediately obvious. However, check to make sure you do not have a relation driving the failing feature. Relations will overwrite flexibility.
