[Gate-users] How to create this - slant hole in a plate

[Simon Stute]

Hi,

Define a box made of your plate material.
The a daughter which is a cylinder made of air.
Incline this cylinder to get the position you need.
The daughter cylinder will escape a bit from its mother volume, but as soon
as the particles are coming from outside those volumes, it will works fine.

Cheers,
Simon
