I resolved my problem. I imported the Stl file from Openscad for Gate.Alex A said:I don't know GATE at all. The underlying GEANT4 appears to support this, but the only relevant info I can find in the GATE manual is that volumes are not allowed to intersect. That is not a great sign.
The only other thing I've found is on their listserv.

If you get no other replies here, I think your options are to play around with the program or join the mailing list and ask.
To cut a geometry in GATE, you will first need to open the geometry file in the GATE software. Then, select the geometry you want to cut and click on the "Cut" tool. You can then use the tool to draw a line or shape on the geometry that you want to cut. Once you have drawn the line, click on the "Cut" button again to complete the cut.
Yes, you can cut multiple geometries at once in GATE by selecting all the geometries you want to cut and using the "Cut" tool on all of them simultaneously. This will create a cut on all the selected geometries at the same time.
When you cut a geometry in GATE, the cut pieces will be separated and become individual geometries. They will remain in the same position as the original geometry, but you can move them around and manipulate them independently.
Yes, you can undo a cut in GATE by using the "Undo" button or by pressing "Ctrl + Z" on your keyboard. This will revert the geometry back to its original state before the cut was made.
Yes, you can make a copy of the original geometry file and make the cuts on the copy instead. This way, the original file will remain intact and you can always refer back to it if needed.
