content: Quote from: blueskull on October 02, 2015, 07:11:28 amI understand what you meant by the solder mask expansion. The area should not be covered by solder mask.But no sure what you asking tho(in the original post)..it is positive expansion

content: It seems like you have a rule which is preventing it from connecting, indeed causing very slightly more clearance than to different nets.Tim

content: @blueskull , the board is quite big with 4 layer( copper floading), and even with high-end soldering iron it will be an issue,btw I using ERSA ICON2 and a Metcal.Anyway thanks for you timePS:Still not getting the expansion issue. perhaps i having a brain fart today. I want it to expose copper

content: @Tim...I suspect as much, but i have failed to locate which rule. Is there any way to restore to default rules in altium?

content: rule editor-> PLane-> Polgon connect style ->decrease the air gap in your polygon.set to 45 degree anglemost likely that connector is so dense the spokes cannot be pulled.

content: so an update..I gave up on the polygon and move on with the routing.And to my surprise the after a few hours of routing, the polygon now pour/connect correctly.I have not change the rules..so i have no idea why it worked now
