Hello Erich,

I have tried the make hole in polygon via the toolbar.  It seems
not to make round holes or I am just not using correctly.  I
have tried using this make hole in polygon several times the
last few days.  It may be that hole does not mean round based
on how I have tried to use the function.

I have been looking at how parts in the library are made.  I
have not found enough details of this yet to attempt making a
air hole part, or more likely hole set 3(wide)x6(long) for the
copper area of sensor board I am trying to make a PCB for.
With a part I can ensure all holes are spaced and sized the
exact same way.  I have a few variations of the sensor board I
like to design, so having a part for the air flow holes.

I also likely need to make parts for different number of screw
terminals and different sizes for screw terminal blocks.
