How can I make a linear pattern number variable?

a_gore

I have a sheet metal part that I can alter the length of using a configuration, along the part I have a set of holes that repeat a given distance set in the linear pattern. I would like to set a variable to change the number of instances but it doesn't seem possible to assign a variable to the number of instances as it's not a dimension. I could set the linear pattern number of instances greater than the length of the part will ever be set to, then the part would get fully populated with holes no mater the change in length. However I don't want any holes to come within a certain length of the end of the part.

Any suggestions on how I could make this work?

Double check your variables.... the number of instances variable needs to be unitless. Not sure if this is your problem, but I've run into it a few times in the past. Here's a quick example....link.

Is the hole made from a sketch? If so, variables won’t work in a sketch pattern. If you create the hole as a feature pattern it will work.

Sorted, thanks guys.
