Hi Chad,

I&#= 39;ll send you the layout later today. It's non proprietary,=C2=A0 just= a personal project.=C2=A0 The layout is complete,=C2=A0 and I just have de= leted the part from the layout, but not the schematic. So the program compl= ains a little.=C2=A0

I&#= 39;ll send you 2 versions. First the completed layout.=C2=A0 Second,=C2=A0 = I'll add back the missing connector, remove the thermals and you can se= e for yourself.

While wr= iting this,=C2=A0 it occurs to me that maybe I can add the thermals first a= nd then place the 2nd connector in that same location.

Hi Gene-

pcb will "allow" you to do bas= ically anything. It should not prevent you from overlapping the components.= This shouldn't even generate a DRC warning.

A= s a general rule, pcb assumes that the human designer knows best and should= n't prevent you from doing most things. It may complain with a DRC warn= ing, but it won't actually prevent you from doing it.
Regarding the plane connection, pcb thermals should work for th= rough-hole components. The surface-mount thermals are implemented yet.

I assume that the overlap warning isn't the one at= 0,0 that we discussed previously? It's helpful to have the problematic= file to evaluate. I've just done a couple of quick tests, and I am abl= e to do what you're describing in my test cases.

Thanks,

I could simply= get rid of the 10-pin header (yeah, I think that's the way to go in th= e short term), and remember to order it. If it's in the schematic thoug= h, it gets into the BOM...which is good.

Anyway, P= CB doesn't allow a couple of things - I cannot make a thermal connectio= n to the plane on either top or bottom of board. Instead, I made some trace= s to the plane. Now DRC reports a problem with too little overlap.

Is this a bug?=C2=A0
