Problem with clearance error
2414 7
H.M. Li 5 years ago
Hi, I am making a simple PCB with just pins connecting to rectangle pads. There weren't any clearance error when I first built it, but after I restart the program I received clearance error on all of the track to rectangle pads connections. I have no clue why this happened. Any idea? Thanks！ ![PCB.jpg](//image.easyeda.com/pullimage/LNGXaeRCyKK9ue3txLYiTYKzKXPIerSBpZJdLKhr.jpeg)

I've noticed a slight change in the new release.  I think there's been a greater than or equal (>=) test changed for a greater than (>) test somewhere in the DRC checker.  Just increase your copper flood clearance by a mil.

@MikeDB Even if I get rid of the copper fill, it is still giving this error.

@1997lihm Sorry can't explain that then.   The new release seems to have a lot of silly bugs.  The graphics refresh is utterly crap for example.

@MikeDB They are different net and get too close.  and the DRC error need to refresh manually. ![图片.png](//image.easyeda.com/pullimage/tLJxhYAFnGhNMpvywrOVynMmAbDUbLdrRk0THJaN.png) ![图片.png](//image.easyeda.com/pullimage/EcVzu0dU0PxknRciEpgYGTm9yypTr19sL9tSmjCC.png) ![图片.png](//image.easyeda.com/pullimage/AyZQEefZ4zRL2YjyPSgqbtIYEd1ZlDLGvh0XXxKt.png)

@UserSupport Ok.  But I've still noticed if the clearance is EQUAL to the allowance then it now seems to sometimes fail whereas before it only failed if LESS than the allowance.

@MikeDB That seems unit issue, if you change PCB unit to mil, maybe you will see the difference. we need to improve it.

Yes the problem is when I use mm.   I think the whole usage of metric needs to improve as it's often impossible to connect reliably to metric pitched devices.
