Making holes in Sketchup

You would think you could make a shape and push/pull it to make a hole, but the method outlined below is more foolproof.

Open SketchUp
Create a base:
Select the Circle tool (C) and create a circle
Select the Push/Pull tool (P) and extrude the circle up
Select the spacebar to choose the Select tool and triple click the cylinder
CTRL+click on the cylinder and select Make Group from the Context Menu:
CTRL+click on the group and select Align Group/Component from the Context Menu:
Click where you want the origin point to be:
Click where you want the end of the X axis:
Click where you want the end of the Y axis:
The popup will appear. Click on No to move the cylinder to the selected spot:
Select the Move tool (M)
Hold the up arrow while dragging the cylinder down:
CTRL+click on the cylinder and select Explode from the Context Menu
Select the Select tool (spacebar) and select both entities:
CTRL+click and select Intersect Faces>With Selection from the Context Menu:
Delete and delete all parts of the cylinder:
Select the interior of the hole with the Selection tool (spacebar) and CTRL+click on the selection and choose Reverse Faces from the Context Menu:
Et, viola, you have a hole
