The aperture made in a polygon with polygon hole tool will also be a
polygon. I assumed you'd be making vent holes that are rectangular. A large
via turned into a hole may do the same job for you, if you want a round
vent hole

Erich

Hello Erich,<br>
<br>
I have tried the make hole in polygon via the toolbar.=C2=A0 It seems<br>
not to make round holes or I am just not using correctly.=C2=A0 I<br>
have tried using this make hole in polygon several times the<br>
last few days.=C2=A0 It may be that hole does not mean round based<br>
on how I have tried to use the function.<br>
<br>
I have been looking at how parts in the library are made.=C2=A0 I<br>
have not found enough details of this yet to attempt making a<br>
air hole part, or more likely hole set 3(wide)x6(long) for the<br>
copper area of sensor board I am trying to make a PCB for.<br>
With a part I can ensure all holes are spaced and sized the<br>
exact same way.=C2=A0 I have a few variations of the sensor board I<br>
like to design, so having a part for the air flow holes.<br>
<br>
I also likely need to make parts for different number of screw<br>
terminals and different sizes for screw terminal blocks.<br>

User - How To Create Very Simple Unique PCB With No Components<br>
<br>
<br>
&gt; There is a tool on the toolbar that allows you to make<br>
&gt; openings/holes in polygons. You should try to get the hang of<br>
&gt; this so you can do this around openings to avoid copper<br>
&gt; coming right up to the edge of the aperture, to prevent<br>
&gt; possible tearing of the copper when the opening is being<br>
&gt; routed. This &quot;pullback&quot; is often around 0.2mm<br>
&gt; <br>
&gt; Regards,<br>
&gt; <br>
