New in SolidWorks 2009 is the Sketch Slot feature.  This sketch entity allows you to quickly create both Straight Slots and Arc Slots in a variety of creation methods.  When you use this type of sketch entity and an Extrude Boss or Cut is created from it, a temporary axis is created not only at the arc center points, but also at the center point of the slot.  The PropertyManager for the Slot sketch entity is shown below.

Stay tuned…more to come!
