I'm trying to create a part that has six sets of holes on it. I want the holes equally spaced. Is there anyway to add this. I've tried linking the dimensions but it isn't letting me add the sixth dimension. I'm assuming it needs that last dimension to be different so that the other dimensions can fit into it.

Is there a formula or function that can allow for this?

I've included a screenshot of the situation.

Cheers,

Place individual centerlines attaching each circle's center points. Give all of these centerlines an equal sketch relation. Draw centerlines from each of the outside circles to the edge of the part. Make these two centerlines equal to each other, with a sketch relation. Dimension how far you want the circles off the edge of the part. Done.
