Nesting - Metric Generic Model line based

[Anonymous]

I am trying to nest a line based family B into another one (A), line based too. Is there a reason why this is not working? I have another family inside the A that I thought could provide a face for the placing of B.

Is there a face required at all? Is there another problem?

A:

B:

I would make Family B to be regular family with instance length and then hosted into the linebase family A. Once you nest it, it will flex with the linebase.

I think this will not work for what I need. The family B needs to be not just stretch, it is an array that is adding or removing segments based on max. constraints of each segment. From what I know the family B has to be line based in order to do all of that... - Or do you have a different experience?

... later during the day I was able to insert the family as initially intended - so my mistake was that I was not in a specific view - the insert option becomes available only in that specific view - the mouse cursor has changed there....

Just use curtainwall if you want it array and stretch at the same time. Doing family like what you want will break eventually. I never find success doing family with array and stretch at the same time. It will break and fixing it way harder than using curtainwall approach.

I have managed to make it work the way I initially wanted, but thank you for the warning about this type of families - that they often fail after some time ....

I haven't tried the curtain family for this purpose yet, but I will.
