This option is not yet activated because the net attributes are not yet fully fixed by Ucamco, in Gerber file format specifications.
(To activate it, see dialog_plot.cpp, line 43)
* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
1. incorrect orientation of components on the bottom side of the board
when the #D model rotation is non-zero
2. failure to export when some components have no model set
2. Whole bunch of pointless casts removed
3. Unused variables removed
4. Fix bug caused by JP on April 25, 2015 where strings were adjusted for translation and the hotkeys section table accidentally swapped the footprint editor title with tag, resulting in "footprint editor" being exported instead of "[footprinteditor]"
No functional changes besides #4, technically it'll "break" imports hotkeys files but April 25 broke imports as well.
reasons:
* This option is called "bad practice" in gerber files format specifications and is even forbidden in gerber drill files.
* Generates problems with some board makers because these holes are not identified in a single NC file.
* No one was able to explain us how to identified them in a single NC file.
* Recent change in drill file generation is not compatible with merged holes (minor reason)
Drill report: serious enhancements.
Plot files names for copper layers: build from the user layer name, like in bzr 4022 stable version. no change for other layers.
* Split graphic circle objects into two 180 degree arcs to prevent the
VRML_LAYER::AddCircle() function from obscuring objects in the hole
(cut out) area of the circle.
PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change.
PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts.
Double definitions will be removed in the (next) future.
* Adds a "Grid Reference Point" to the VRML export; this allows a user to specify the (X,Y) coordinate which will be the origin point on the output
* Adds a "Grid Reference Point" to the IDF export; this is similar in purpose to the corresponding VRML export feature.
added the example gen_gerber_and_drill_files_board.py in demos, which shows how to do that.
Fix a Printf format issue (shown in Debug mode) in Libedit (%d used for a size_t, changed in %zu)
legacy plugin: better compatibility with old brd files (current track width and current vias size, stored in SETUP section, were not read from file and incorrectly set)
