Hello! How I can creat spheric segment with 2cm radius? I’m using Segment Editor, but I don’t know how to change spheres radius. Thank you for your answers!

Click the % button next to the size preset buttons to switch from “percentage of screen size” to “millimeter”.

Check “Sphere brush” checkbox to switch from paint with a disk to paint with a sphere.
