Family parameter not working when inserted

[jonathan.parsons1]

Can someone please try the attached family and tell me why it doesn't work when I switch between the two types (A306 and A307). The 'Bench Width' parameter does not change with the bench 'Type'.

I imagine it is a simple error as it is the first time I have tried to do this.

Thanks

Hi,

Your parameter is instance-driven and not type. Either change it to type or put this formula for example:

if(A307, 1300 mm, 660 mm)

Excellent. Thought I had tried the Type type but must have messed it up.

Formula is great, thanks
