Hmm - ok, I created the cylinder for large hole (spider1.jpg) and made
it a component...

Moved it into the proper position and did "intersect with model"
(spider2.jpg)...

But when I attempted to delete the component, all I had was the original
blank (spider3.jpg)...

What am I missing?

OK ... attached is your "tutorial" for making holes in curved surfaces,
which takes you step by step through the process. Just click on each
successive "scene" tab.

Be aware that this is just one method ... there are other ways to skin this
cat in SketchUp.
