Hello, I'm frustrated. I tried hard to find the reason because the Gerber Viewer shows a clearance-min in Analyses Results of 50µm. Eagle tested the PCB for 6 mil (150µm) clearance without any error. I exported the Gerber files from gerbv (opensource) to a PNG with high resolution and searched for the small clearance in the picture inch by inch and did not find such a small clearance. Is there any way to show the location of the smallest clearance in the Gerber Viewer? It may be a bug in Eagle Gerber cam or in Eagle itself or even in the Gerber Viewer ;-) Do you have any hints to solve this problem? For the technical stuff: The uploaded file name was "TDcortex.zip" Regards Frank
