Visibility's dependent on Two Parameters | Matrix

[Anonymous]

Hello,

So I have two parameters at play here:

 1. PalletsPerBay

Determines no. pallets on x-axis

2. No.Beams 

Determines no. pallets on y-axis

I need the families two be dependent on both parameters. Please see image attached. 

I used a couple of if(and()) statements but this seems tedious. Is there an easier way to do this? Maybe I could create visibility parameters dependent on two conditions? 

(I forgot to add 01, 02, & 03 parameters to the list, but the idea remains the same)

Why don't you nest the pallet family in the beam family so that when you place a beam the pallet comes with it?

Are you Arraying in both the x and y directions simultaneously?  If so, I've accomplished something similar by nesting a parametric array into another parametric array, which in turn, is nested into a host.

Thanks for the advice guys.

@barthbradley, I don't believe an array will work as there could be 1 pallet per bay, and you need at least 2 for an array, correct?

@ToanDN, @barthbradley

So I nested the pallets with the beams in a family: Beams&Pallets.

Please refer to image attached:
- Blue indicates hidden beams

- Red indicates hidden pallets

The nested families that are hidden are dependent only on the No.Beams visibility of host Beams&Pallets family, and therefore hide easily.

However:

Pallets 22, 23, 32, 33 are dependent on No.Beams in host family (Rack) and PalletsPerBeam in nested family (Beams&Pallets). Now they won't hide unless No.Beams & PalletsPerBeam yes/no is false. 

How can I resolve this?

Thanks in advance,

Connor

So as a solution:

I created instance yes/no parameters for Pallet 2 & Pallet 3 in Beams&Pallets associated to their relevant pallets.

Then I associated these instance parameters to equivalent yes/no parameters in the host, which I made dependent on if statement formulas. 

Let me know if you guys know of a better way to go about it please.

You can use array. Insert two modules in the same place, assign one with a vis param "array", one with a vis param "single". Enter a formula for "single" = not (array). Array parametrically the "array" module as usual. When you need 1 module, use a chexkbox to turn off "array" then "single" will show.

Actually, I have array families that have a single element state. This is easily accomplished through On/Off parameters. One  On/Off parameter controls the visibility of the element Array and another On/Off parameter controls the visibility of a single element.  So, if than number of elements is less the 2; the Array default to 2 elements and becomes invisible, and the single element becomes visible.

Ja, Toan did mention that. Thanks man.
