jean-pierre charras a18d3cca6e Pcbnew, zone filler: Ensure hatch pattern thickness bigger than zone minimal width (one micron bigger).
This margin is mandatory to avoid incorrect polygons in Gerber files:
due to the fact Gerber units can be 10 nm (and Gerbview internal unit is also 10nm), valid polygons
can be converted to non valid (self intersecting for instance) by coordinates truncation.
This is a known problem in Gerber files (not specific to Gerber format)

jean-pierre charras bd34348068 Pcbnew: allows using filled polygons in zones with no outline thickness.
This option was only available if advanced config "ForceThickZones" was set.

jean-pierre charras d208447cba Zone filler: clamp thermal stub width to the pad minimal size.
Setting stub width to a ridiculous large value (for instance 100 times the pad size) creates strange and broken shapes,
and obviously stubs cannot be built.
Ensure also the thermal shape is inside the zone boundary (because the algo adds areas this was previously possible)

Jeff Young d4054029cd Shrink/expand zone by minimum width only after doing all knockouts.
It's too complicated trying to keep everything smaller or larger by

Jeff Young 79cd457ba7 Implement thermal spokes for custom pad shapes.
The thermal spokes are anchored at the pad anchor.  They may or may
not make sense, depending on the pad shape.  It's up to the author
to move the anchor around as necessary or to not use thermals.
2019-06-25 11:34:28 +01:00
Jeff Young 5c89e4490e Change zone fill algorithm to better handle thermal reliefs.
Thermal reliefs must not knock-out spokes of other pads, while
clearances must knock-out spokes of all pads.  Therefore we now
do all thermal reliefs, then all spokes, then all clearances.

Seth Hillbrand 6bcf1839b7 pcbnew: Add arc approximation setting to board
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments.  This allows the user to customize their speed vs. accuracy
tradeoff.  The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.

jean-pierre charras 4e5a94efb7 Pcbnew, non copper zones: fix 2 issues.
1 - For debug purposes, the code to fill non copper zones was disabled and the copper zone code was uses instead.
It creates issues with pad clearance areas, because a non copper zone has no clearance areas.
2 - The non copper zone dialog had no option to set the outline smoothing option.
Unfortunately, this parameter was inherited from the last edited copper zone.
And therefore the non copper zone can have a non wanted outline smoothing option.
This option is now added to the dialog.

jean-pierre charras 7170720f3c Allow hatch pattern in filled zones
the filled areas can use a hatch pattern (crossing lines) using square holes.
The zone filler removes too small holes (truncated holes) from hatch pattern.
It avoid to create small holes when a hole pattern is truncated by the filled area base shape.

jean-pierre charras fdfe5eabfb Fix incorrect detection of filled zones changes in DRC check.
Commit 6006703798 fixed a crash but broke the filled zones changes detection.
Filled zones were always seen as not up to date due to the fact the filled areas were cleared too early.

The up to date detection is also optimized: the old filled polygons are no longer stored.
Instead of, the MD5_HASH is calculated and stored before clearing the filled polygons.

jean-pierre charras 353d9d7c9e Pcbnew, Zone refill: avoid useless refilling, when zone parameters are not modified.
Previously, in many cases the selected zone was refilled on exit selection, even if the zone was not modified.
This is annoying, because the zone fill can be really time consuming, and cannot be called without a good reason.
Now the refilling is made only if a zone parameter is actually modified.

jean-pierre charras b9944e2c06 Thermal reliefs: fix a corner case that wrongly removes a stub in a thermal shape.
This was due to the stub removal tests if a stub end is outside a solid area to remove it.
There is a corner case: is the stub end is exactly on a solid area outline extra segment
created by Fracture() used in calculations.

The stub removal tests are now made before fracturing.
