Some precisions:<br><br>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.<br>Also, you will have ellipses cross-sections between the plate borders and the cylinder.<br>

<br>
I am not totally sure about the geometry you want to create for the hole but I added the following<br>
volume in Gate v6.2 which is an Elliptical Tube. You might try it and see if it suites your needs.<br>
<br>
See the User's guide:<br>

Don't know if it will help.<br>

<p class="MsoNormal">If you look at the source code, you'll see that the volumes that Gate supports are Geant4 volumes. A look at the Geant4 source code reveals that it supports many more volumes than Gate. There might be one or more volumes that suit your
need in there. You just need to implement it in Gate (using the current source code as a template). It should be relatively straight forward... but your geometry need is a bit complex...<u></u><u></u></p>
