DXF blocks are virtual groups of items.
The insert entity is what actually places all the block contents at a given coordinate.
This should fix importing drawings from professional CAD tools like SolidWorks that will have a good bit of blocks.
The reality is the DXF file can still override the selected unit option which is totally fine.
In fact, per specification, there is a way to change units mid-file with block records :/
There is no guarantee DXF contains $INSUNIT to specify the units of the file as its optional.
This allows the user to specify the expected units via dropdown.
SolidWorks can definitely generate such unit lacking files as an example
ADDED: Allow DXF/SVG graphics to be imported as a group
Also, cleanup the placement routine to allow the edit tool's flip
and rotate routines to be used when placing the items.
CHANGED: Settings are now stored in versioned sub-directories
ADDED: First-run dialog for migrating settings from a previous version
CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files
CHANGED: Color settings are now all stored in a separate settings file
CHANGED: The symbol editor and footprint editor now have their own settings files
CHANGED: Color settings are no longer exposed through BOARD object
CHANGED: Page layout editor now uses Eeschema's color scheme
Settings are now managed through a central SETTINGS_MANAGER held by PGM_BASE.
Existing settings will be migrated from the wxConfig format on first run of each application.
Per-application settings are now stored in one class for each application.
Sometimes a dxf curve is a "degenerated" bezier curve having only 3 points.
(a control point is at same location as a end point)
This commit fix incorrect import of these curves.
This update replaces the existing uses of unique pointer creation with
the C++14 std::make_unique call that provides proper memory release in
event of an exception.
BLOCK elements in DXF are re-usable bits that are useful when editing
the file but should not be shown when importing the model. This skips
all references except those that exist in the default "*Model_Space".
This block is required in each DXF file and cannot be renamed.
Fixes: lp:1790821
* https://bugs.launchpad.net/kicad/+bug/1790821
* Fix wildcard display in the file selector dialog (on GTK
it would show the regex to the user)
* Move the file extension comparison into a common function
Use the HTML_MESSAGE_BOX window to present the warning messages rather
than wxMessageBox which would overflow the display when there were a lot
of graphic items that could not be parsed.
