Hey

I'm currently routing a PCB for fabrication, but I get some weird clearance problems when running the DRC (see image). It seems to be leftovers from either traces or the ground plane, and I can't select or delete them. Of course the clearance errors disappear if I increase the spacing between the actual trace and the leftover traces (or whatever it is), but I'd like to just have them deleted. Running 'ratsnest' doesn't solve the issue.

Any ideas?

Thanks!

Kind regards,
Anders

Hi

Those marks indicate the DRC errors.
To be rid of them you clear the errors.
TOOLS > ERRORS > Clear all

Running the DRC on a board that meets your design rules also gets rid of
them so either you have not set your design rules to reflect your
manufacturing constraints or your design is breaching your rules.

Hi Warren,

It's a bit strange since I loaded the SeeedStudio DRC before I started routing, so the traces shouldn't have exceeded the limits. But you're right, approving the errors removes the marks. I'll just increase the clearance a bit to solve it. Thanks a lot!
