Creating Slots
You can create slots from holes using the Pull tool. You can also edit slots. Slots maintain the relationship between their faces.
If you pull a hole with a rounded or chamfered edge into a slot, the slot will have a rounded or chamfered edge.
Note: You must select the axis of the hole, rather than the axis of a round or chamfer
on the hole. You will not be able to pull the slot if you select the axis of the
round or chamfer.
