A width of .050 is quite large, and may prevent the ground plane from flowing between many adjacent pads and other areas, so check it carefully. I'm surprised it took that long at .016, that's not really that small. Are you really sure it defaulted to what you thought it did? If you've still got the old version, do a VIEW > INFO on the polygon to check. Otherwise try setting it explicitly to .016. The time should be roughly proportional to the inverse of the square of the width. If it took 2 minutes at .050, then it should take about 20 minutes at .016. Actually it will take a bit longer if the plane now flows into more spaces, and there are probably some other inefficiencies, but I still don't see how it should take 6 hours. Is the smaller setting possibly causing RAM usage to exceed the real memory size? Once the OS starts thrashing things can slow down by an order of magnitude or two. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
