Add Suppression Control to the Pattern Creation Dialog

[brian.cranston]

Sometimes one knows they are going to suppress some instances of a feature pattern. Could you generate a basic representation of the pattern and allow the user to deselect instances before executing the pattern feature? 

Example... A 4x4 pattern might present a dialog like this... Here I've deselected several boxes and they change from a green "Y" to a red "N", meaning the N's are suppressed instances.  Polar patterns appear like pie pieces. Other patterns could display as one row?

Y	Y	Y	N
N	N	N	N
Y	Y	Y	Y
N	Y	Y	Y
