To my knowledge, the DXF plotting never worked this way. It originally drew and outline of the board outline segments so the board outline had width with intersecting rounded ends except arcs which where drawn as a single line so it had many issues.
dxf worked fine please find attached what dxf was and what is now -rev 4022 fully usable (arcs and line correctly aligned) -rev 6684 fully useless for mechanical interchange as Lorenzo said
Before we had (for the whole plotting world): - Line: only the midpoint - Sketch: the line outline (two lines joined by arcs) - Filled: well, in DXF it was the same as sketch... I considered LWPOLY but they weren't too portable at the time All of 3 have their use

I wasn't following correctly. What you are asking for is a single line outline of the board. To my knowledge, the DXF plotting never worked this way. It originally drew and outline of the board outline segments so the board outline had width with intersecting rounded ends except arcs which where drawn as a single line so it had many issues. We could provide this if someone has the time to code it but it must be implemented as an option so the current DXF plot behavior can be maintained.

I didn't know that this was discussed so deeply, I just noticed there were no reply at all ... If you design some mechanical parts inside pcbnew (i.e. an enclosure for the board) it is necessary to export this draw to DXF as a single line to send this to mechanical production... I still consider this a very useful feature missing in KiCAD but available in most ECADs... Still I have some hope that could be revived ... Anyway @ Nick, if you can reach the person who needs this feature, you can tell him/her to contact me... I have some workaround to export pcbnew drawings to DXF; moreover my kicad StepUp script could be slighty modified to import the drawings in FreeCAD and the directly manipulate those or export to DXF... but those are just workaround Regards Maurice On 11/04/2016 19.42, Wayne Stambaugh wrote:This has already been discussed. The decision to change from the line drawing to the polygon outlines was at my request. JP graciously changed the DXF line drawings to the actual polygon shapes generated by the intersection of the line output. I requested this because the line drawings required massive amounts of effort to convert to polygons. I will not ask JP to change it back or add an option to use the line drawings. If someone is willing to step up to the plate and re-implement the line drawing dxf output, I'm OK with that as long as it's optional and the polygon output is kept in tact.

Since it describes the problem pretty well with the attached images. So is this by intention or not that one can not use the plot mode combobox now? I just tested in 6673 on windows. Regards Nick Østergaard 2015-06-19 12:37 GMT+02:00 easyw <easyw@xxxxxxxxxxxx>:Hi, I'm plotting some mechanical parts using pcbnew in old stable release (4022) it was possible to plot DXF with the option Mode:Line then the mechanical DXF exported was fine with single Line objects now (5785) it is not possible anymore ... it seems that the Line mode option is gone... the result is an object double lined as in the attached images... I tried to just enable 'm_plotModeOpt->Enable( true );' and adding choice Line to the form, but it is not enough... could someone help me in finding where I should search to add this option? I think that for exporting mechanical parts (related to the pcb board) it is useful to have Line mode available... thanks Maurice _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
