>From my point of view, MCAD tools and EDA tools are 2 different worlds. So "asking about aligning the origin of a DXF import to the pcbnew grid" make not really sense. Moreover, Pcbnew has a lot of grids, and a Y axis reversed. A dialog specifying UNIT (mm, inch) and X, Y position on the board of the DXF origin makes more sense. But it is not a greater flexibility. Constraints to create an outline in Pcbnew and in a MCAD tool are very different. It could be just an other option. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
