Bracing at second array family

[Mat.Syaf]

Hi, I have an issue here. 

How do I make the Bracing (the X dotted line) always appear in the even number of the array family?

Thank you

Can you upload the family to check it?

Make it as a second array. Place the first one on the second of the first array, place the second one on the fourth of the first array, and write a formula so the correct number shows.

You'll need to use visibility parameters and a second X for cases where there is only one.

[Mat.Syaf]

yes sure. @rxi.gg 

[Mat.Syaf]

can you share the formula so the correct number will show accordingly?

for the visibility, i don't think array can make the family appear less that 2.

Why don't you array two elements - one with "x" and one without?  

...Or just make the "x" a separate Array?

I upload you the family edited. I create a new parameter and a new array for the lines

- cannot 2 elements because sometimes odd number of elements might happen.

- yes, need to separate array for X, but seems like bro @rxi.gg have solved my problem. 😁

Thank you very much bro! That's the formula that I looking for to put in "Support Bracing" parameter. 😃

If you are interested, check this revision out. A added a few parameters to make it flex better. You needed some way to deal with a <2 Array, which Revit won't allow.  Open the revised RFA from the attached RVT.

wow. This is the complete solution for my case. haha 😲
The solution from @rxi.gg already solved my main question for this Posts.

Yet the minimum element can be shown is only 2. If less than 2, it will clash and have to delete the family or keep it 2 elements. My idea to solve this issue is to create another family for single element only.

But seem your solution already solve my second issue. Now I need to understand the formulas in the parameter. 😂

Thanks bro!
