Hi there,

I am attempting to create a parametrable family of aluminium tubes to apply to a facade and am having trouble with the separation dimension paramaters between tubes within a repeating group. Each time I test the family by modifying one of the "Sep tube" parameters I get the error message "the constraints are not satisfied".

I will attach the family file if someone can have a look...... I'm working in France, so for some of the parameters you will truly need to pardon my french :-) . 

Thanks

I don't think you can have instant parameters to set for all the "sep tube" because all those tube are now a array group. I would make the parameter as a type parameter for those who are inside the array group.

If you want to adjust the spacing between each "tube", you might be able to get away with it by setting different "types" within the same family.

Revit doesn't seem to play nice with trying to control items within groups. Something you could try is making a new family for the tubes set up with parameters to control the tube spacing, then nesting that family into the family you uploaded and arraying the nested family.

 

You can control parameters in nested families with parameters in the base family, e.g. 'Sep tube 1' can control 'Sep tube 1' in the nested family.

 

I'm attaching a quick edit to your family so you can see exactly what I'm talking about. It needs a lot of cleanup, but it seems to work.
