Adding bits to the library

Hi All;

I’m a newbie here, I’ve got an XC on order and have been using one at a local maker space in Baltimore. I wanted to ask the community if it’s possible to add a custom bit to the library? I also wanted to ask why there are no downcut bit listed?

The Easel bit selector really only takes diameter into account, unless you choose one of the V-bits (Pro). You can type a custom diameter in.

To address the up vs down cut issue, using one or the other doesn’t change the toolpath, just changes how it cuts the wood and the surface finishing.
