Hello,

I've started working with Eagle for about 3 weeks now and love the accessibility of this software!

Can somebody tell me if there is a possibility to make a cutout (circle) in a polygon in the package editor?
I've tried it by creating a circle on layer 42 (bRestrict) without any result.

Hi

You need to make the hole part of the polygon edge.
Attached is a library/package that shows the steps.

Before you start set the 'Alternate Grid' to finest.
I've drawn on layer 34 for clarity
Set the wire width to something greater than your DRC will require. 8mil
is used here

Some comments relating to the numbering of the steps.

(1)
(a) Draw a circle at the desired point for guidance, It will be removed
later. Here it has width(8 mil) but you can use a zero width circle
(filled) and work to it's edge if the circle diameter is critical.
(b) Draw a polygon edge for each portion of the sections that approach
the circle, like the tent shape in step 1.
(c)Don't let two straight sections become aligned or the edges may/will
become one and you will have to split them again.

(3)
To bend that straight line to an arc, select MOVE, Hold down CTL and
click in the middle of the straight line and drag to match the shape of
the guiding circle. It will jump using the standard grid so hold down
the ALT key to activate the alternate grid.

(7)
As you tidy up the the final edges, don't let them cross or be exactly
upon one another. the polygon will be invalid. Keep the centres of the
wires slightly apart and yet the wires are still overlapping
