I am currently trying to build a package for a through hole potentiometer in Eagle Cad and I wanted to incorporate holes in my PCB for the metal tabs on the side of the pot. I determined that these holes should be at least 1.8 mm in diameter. However, the moment I select a diameter greater than 1.0 mm I get this weird forward slash through my drill hole icon and I'm not sure if this is okay or what it means (see figure below). Here is the datasheet: https://www.bourns.com/docs/Product-Datasheets/PTV09.pdf. I am using PTV09A-4 (Horizontal/Rear Mount, Bushingless)
Thank you!
