For some mysterious reason, HW holes no longer show in a cylindrical body, but holes in planar faces are OK.
Bottom row of hole options is greyed out.
Running SW16-SP4 (Standard) with Windows 10 Pro, and nVida Quadro K600 with 10.18.13.5456 driver as recommended by the Rx utility.
Have rebooted system and reset registry to no avail.
Anybody else experiencing this problem?
