I have a board that has a GND zone on the top and on the bottom. Normally, I would connect the two zones in various places around the board with vias. However, PCBNew does not support this functionality. For one, a lone via cannot be placed onto the board if it is not connected to a pad somehow. And secondly, If there is a lone via somewhere on the board (this can happen if the save file is manually edited) the Zones do not connect to it even if they are in the same net. I am trying to add this functionality, however I am unsure how to go about it.
It seems that the "AddClearanceAreasPolygonsToPolysList" function found in "zones_convert_brd_items_to_polygons_with_Boost.cpp" is what removes the zone area from around the via. Specifically, there is a for loop at line 258 which goes through the Tracks (and segvias) and removes the area around those that are on the same layer, but of a different net. However, I can't figure out why this would be removing the area from around the lone segvias even though they are of the same net? I notice also that these lone vias when drawn by Pcbnew do not have there net labeled like the connected ones. This leads me to believe that the segvias are somehow 'forgetting' their net info if they are not connected to some other item in the same net, or that they are not are not being included in that net for some reason. Are there any ideas as to what to check to see whats causing this. If i am correct I will look into adding the necessary code to allow lone vias which hold onto their individual drill and diameter size. I am also wondering if there is any interest in being able to modify individual vias. The save function saves this information for each individual via, so it would just be a matter of adding a dialog? _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
