I have just started using blender and downloaded the latest version. When I try to do boolean operations, the “w” key doesn’t show up as the manual says, and the “F9” key does nothing. All I’m trying to do is subtract a horizontal column from a flat plate to create a coin holder. I have spent 4 hours looking for the magic key and can’t find it.
You have 2 options:
Boolean operators are a modifier - so go to the modifier properties (Properties buttons - Look for a spanner icon in the menu bar) and add a Boolean modifier for you plane. Make it Subtract, use the cube as the other object and then his “Apply” to make the change permanent.
Alternately (Sans Modifier): Select the plane in edit mode, hit “E” for Extrude, then hit “S” to scale the extruded section. You’ll end up with a smaller square in your plane. Now scale the square to the shape you want it - select and delete “X” the face only from the middle, then extrude the edges of your hole down to make the coin slot!
