Detail family's Parametric Array does not work when family is nested.

[Sahay_R]

Hello all, 

I have created a Detail family which has a formula driven Parametric Array. The formula is driven by the Width parameter. When I nest this into a generic model family, the array does not work even though the Width parameter has been associated with the corresponding parameter in the host.

What could be going on?

Post the family.

I tried the same thing with the same parameters just different values, it works for me. what I did though is put the instance values again the generic model family for e1 e2 and spacing by selecting the detail family, then associated the width. 

Check mine.

@dferreira-blackwell - precisely what I have done....

@barthbradley  - here is the family.  Look at a side view for the detail family. Try increasing the value of Width in the Host family to 15 or 20 or so.

Interesting twist - when I increased the value of Width significantly in the nested family, the array worked in the host family until Width reached the max in the nested family. Right now it works to a max of 10'. Kind of a workaround.

I've encountered this before. The fix I've found is to array it beyond any length/number that will actually ever be used and then reload it into the parent.

@Sahay_R 

• Model the detail item and its array in a "Line Based Detail Item"
• Instead of width use the built in length of the LBDI family
• 

• Nest it into the generic model
• lock start/end to the extrusion
• and it will function as intended without associating any parameters

Thanks man! One of the guys here was having the same problem and I've been trying to fix it for the past 3 days. Putting it in a line based as you suggested got it to work flawlessly. I wonder what is the difference between the two templates that it works in one but not the other!
