We just updated from 2016 to 2018. We have custom holes that we use for dowel pins. This allows us to call them out easily on our drawings. We also have custom cbore and tapped holes, and they are working fine. When we go to choose a dowel hole we get the attached error.
I have tried multiple things to fix this and nothing is working. My VAR couldn't fix so they have sent to SW. I am trying to find a quick solution!
