Easy way to change diameter of holes?

Hey everyone,
Is there a fast and easy way to change the diameter of a hole to an exact size? I’m working on a mechanical design where I have a lot of holes in a flat panel and need to resize a bunch of these holes to accommodate different fasteners.

This is probably the moment you should start working with Grasshopper :slight_smile:

Command “modifyradius” should help.

The command ModifyRadius doesn’t do anything on a Round hole created with Rhino Solid Tools…
