Another development release 0.9.8N (rc-9) is now available for download...
http://www.cambam.info/downloads/#devtIn this release...
* Bug fix : Surface - plane slice X and Y axis bug where the surface has vertical faces.
Also fixed is plane slicing the Z axis when multiple surfaces are selected.
* An extra check for lead in spiral angles, to prevent things like ramp angle = 180 degrees causing an infinite loop.
* Drilling operations now use the 'Start Point' property when optimising the drill order.
(Previously the first selected point was always used as the start point... and still is when no start point is defined).
* There are a few new macros to the post processor:
{$arc.start} {$arc.end} {$arc.sweep}
These are the arc move's angles in degrees.
Thanks again for all the testing and bug reports!
