I get the following error when I run design rules check:
Footprint has incorrect courtyard (not a closed shape)
@(3.7270 in, 2.5500 in): Footprint J4 on F.Cu
I can find no reason for this. In fact I use the same footprint twice on the same PCB board, J2 and J4. Design rules check does not have a problem with the footprint as use for J2. I selected the footprint for J4, chose properties and clicked “Update Footprint from Library…” just to insure that I did not inadvertently corrupted the footprint on the PCB. The footprint used for J2 and J4 is the same footprint in the same library. Any help would be appreciated.
A second but less important question is that there is an circled X at the top of U1. I am sure that it is the result of something I did but I do not know what it means, or how to delete it. Again any help would be appreciated.
I am sorry if this update is confusing but I had several screen captures of the PCB and the design rules check dialog but I get a message that new users cannot upload attachments.
