holes on circumference of a cylinder

[Jasper]

I have modeled a hollow cylinder and I need to reduce its weight by putting holes in its circumference, essentially making a perforated tube.
What is the best/easiest way to achieve this? The feature pattern tool doesn't seem to support cylinders. Creating lots of tangent planes for sketched holes seems very tedious.

Thanks,
PJ

Tangent planes is what I do. But I usually only want a couple holes, not a lot of them.

Remember, each plane can make two sets of holes diametrically opposite.

Yeah, I need a lot of holes. Not looking forward to it.

PJ -- Besides making a Radial Copy of your initial (Tangent Plane defined) Hole You can make a SheetMetal Cylinder out of Perforated stock (something I regularly do to make pyro ignition devices). Alternatively I often create two or three Radial Copy Patterns that can then be Linearly Copied down the length of a Cylindrical Tube.

Radial pattern, like Lew says.
