Good point, I don't use that very often. > Ever since I made selection through thin-drawn polys work, I much > prefer it.

I'm rendering with OpenGL, and its translucent - so doesn't bother me ;) I'm also not working with the luxury of >2 layers, so there are loads of places where my polygons are cleared away - and it isn't as immediately obvious that they still reach certain areas with thin-draw-poly. I know the connectivity check catches it, but it isn't quite the same. This said.. perhaps I should be using ground tracking more (with the CLEARPOLY flag reset), to ensure I always think more carefully about where the ground returns are on these 2 layer boards. Only problem then, is that you have to make sure not to mess up the thermals. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
