The attached patch makes the following changes to import DXF:
1. correctly implements scaling based on DXF $INSUNITS -
at least where INSUNITS is sensible. I ignore units like miles,
gigameters, AU, lightyear, parsec ...
2. correctly implements LWPolylines, adding an ARC segment
rather than a line segment when bulge != 0. A number of users
have been complaining about getting the wrong board shape
(chamfered corners rather than rounded corners) on DXF Import,
now they shouldn't complain.
The DXF format polylines and lwpolylines have a 'flags' field of which bit 0 indicates if the polyline/lwpolyline is to be closed or open.
This flags field is correctly read during the import but in the conversion to board segments, was previously not used.
- DIALOG_DXF_IMPORT works with PCB_BASE_FRAME instead of PCB_EDIT_FRAME
- imported items are not immediately added to a BOARD
- imported items are held in a list, instead of vector
- imported items are instantly visible in GAL view
- added DIALOG_DXF_IMPORT::GetImportedItems()
- code formatting
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
The old Cu stack required knowing the count of Cu layers to make
sense of the layer number when converting to many exported file types.
The new Cu stack is more commonly used, although ours still gives
B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
You will need to convert to the format immediately, *.kicad_pcb and
*.kicad_mod (=pretty) since legacy format was never going to know
about 32 Cu layers and additional technical layers and the reversed Cu
stack.
Pcbnew:, libedit, Save lib as...: the new .pretty lib format is the default, instead of legacy .mod format. The legacy format is still selectable in the file selection dialog.
Fix issues created by this patch.
Note, this fix slightly changes the vertical position of these texts.
This is not really a problem in eeschema, but in pcbnew this is perhaps more annoying, if the verical multiline text is critical.
Fix a very minor issue for vertical justification of single line texts in dxf import.
