Hi Guys

I want to use an equation in a part file to drive the number of cross members in a structure I need depending on the overall dimensions. Basically what I want to do is to keep the pitch of the cross members within a max distance and then calculate the number of cross members needed evenly spaced. I do know how to use equations to create evenly spaced members but I need help with the max limit and inserting a new cross member I assume I would use linear pattern for the first member and then write the equation from there but my equation skills are not the best from there. I am sure this will be a very easy answer for alot of you and if you could take the time to help me I would appreciate it.

Cheers Dee
