Hello everyone,

Started using FreeCAD today and loving it so far however I can't seem to figure out how to do this one thing.

I created a cylinder with an inner diameter of 41 mm and I want to put 10 slices with a diameter of 40 mm and a thickness of 0.5 mm inside while at the same time being spaced out 9.75 mm from the each other and 4.875 mm from the end of the cylinder.

I can find out how to fill the whole cylinder with another cylinder with diameter 40 mm but how to add air between the slices is something I can't seem to figure out. Could anyone point me in the right direction? Thanks in advance.
