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

Actually I asked this question when we were having Gate 5.  I moved down to Geant4 for the reason.  Now I want to check it again since we have Gate 6 now.  I may need more detailed  help on adding source code to Gate because I haven't never touched the source code and don't know its structure.

As far as I know, this is not possible with the current geometry features of Gate.

However, since Gate is open source, you can add the feature yourself!

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...

Good luck!

I need to create a geometry in GATE that is a solid plate with a through-hole in it and the axis of the hole has a slant angle to the surface of the plate (not perpendicular).  Can somebody help me how to do it?
