Hello, I have been a part time user of Solidworks for about 6 years, for the last 4 months I am now a full time user with my new promotion.  This is driving me to learn more and make smarter models since I am more involved now.  I mostly model sheetmetal parts.  I am discovering how valuable equations are and have stumbled across an issue, maybe I am asking for something that is not possible.  I am designing a product that will be anywhere from 2' to 9.5' long growing in .5' increments.  I am trying to write an equation that will suppress a hole every time the length equals X.5' long and unsuppress it evertime the length equals X' long.  I can write an iif statement to do greater than or less than a number to suppress, but I need it to suppress when the length equals 114", 102", 90", 78", 66", 54", 42", and 30".  Does an iif statement only work for less than or greater than statements, not equal to statements?  Thanks for any support I receive.
