In both Wildfire 3 and Wildfire 4 you can use a config option for different ways to select sketcher references; 0,1,2 you can select it how many references Pro/E sketcher will automatically select

sketcher_auto_create_refs

set it to either 0,1, or 2

Starting with Wildfire 3 PTC added a Sketcher Palette; it includes many shapes such as Polygons of all sorts, Stars with up to 20 points; and some other shapes, but along with this we can customize the palette and ad our own shapes along with our very own tab, and here is how:

to add a Tab to the Sketcher Palette simply browse to:
