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

[Simon Stute]

Some precisions:

My solution is not strictly correct. It will be correct only if you have
air around your plate, for at least the same dimensions as those of the
piece of cylinder that goes outside the plate.
Also, you will have ellipses cross-sections between the plate borders and
the cylinder.

Cheers,
Simon
