Arrey parameter. Can't go below value 2?

[jakob_hansson]

I want this family to be stretchedable in y and x axis. The family works the way i want exept that i can't go below value 2 in my arrey parameters. I suspect it is becaouse i  have used same block (in the middle) for all the arrey copies in all directions. Is it possible to go below value 2 in a array parameter,  are there any other possibilities to make this work?

Currently Arrays have to have at least 2 (the original + one or more arrayed objects). when I have had this issue in the past, I made 2 types in the family that I controlled with Visibility parameter. 

• In one Family Type the visibility was set to display with just one of the items On and the Array Off.
• In the other Family Type I had the Array On and the single item Off.

Attached family should provide the information you seek.  Make sure your Preview Visibility is turned on in the Family when you flex it (e.g. shorten the length).  That way you can clearly see how the less than 2 condition looks.

While you can control array qty using visibility parameter+ a formula, looking at your sample I think using a Roof > Sloped Glazing would be a better and easier way to approach it.  There is no longger a minimum of 2 restriction, you can even go partial panels.
