Linear Pattern with Increasing Size

[jakvett]

I want to make a drill bit organizer. It consists of sheet metal with a hole for each size of drill bit. A very basic part, I just want to know if there is a shortcut in the modeling. My plan is to linear pattern (sketch or feature) a single hole. My question is, is there a way to linear pattern while increasing the size of the hole by a set amount with every instance? Ex. the first hole is 1/8" the next is 1/4", etc. I know I can just dimension each hole, but again, I'm just wondering if there's a quick way to model such things.

Look into the Vary Sketch option.

Exactly what I was looking for. Thank you. Do you know what makes it greyed out sometimes?

Usually, not selecting the correct variable dimension.

I have attached an example of using the vary sketch feature, but I need to know how to modify it. As you can see in the part, the linear pattern is derived from the distance between the center of each circle. Because of this, the edges must get closer together as the radius increases. How can I change the pattern to keep the minimum distance between the circle's edge constant?

To control three variables (diameter, spacing & quantity) you will have to place the holes manually.
