R Patern Warning on hole patern when changing parameter

administratieWFZXC — Thu, 30 Oct 2025 17:58:41 GMT

Hi!

I'm trying to use parameters to make a hole grid on a board, however when I edit my LengthWidth Parameter I get the following error:

R-Pattern1

Compute Warning

The expression specifying the pattern count does not evaluate to an exact integer value. Edit the expression to repair it.

Any thought on solving this error? The design updates as intended (Extra holes get added when I enlarge the board, Holes get removed when I shrink the board)

See attached file and a snapshot for reference

Any help is greatly appreciated 🙂

You've done a lot of hard work to make Fusion's calculations more difficult.

(view in My Videos)

Of course, your equations do not allow for rounding or conditions, so you must remember that the dimensions must be multiples of the array element's pitch value.

Thank you @kacper.suchomski for your help! Yes, I'm good at making things more difficult 🙂

I thought I needed to divide by 1mm to use the distance values as a quantity value, but now I see that's not necessary. lots to learn!
