The following commits were squashed into this
[Sketcher] Handle some corner cases in AngleViaPoint
[Sketcher] Avoid redundant constraints with B-splines...
When involving tangent, perpendicular and angle constraints.
[Sketcher] Add pre-commit changes
[Sketcher] Do not allow 2-selection tangent with B-spline
Also...
[Sketcher] Report error when using direct tangency with B-splines
[Sketcher] Fix malformed constraint when B-spline is selected second
To clarify, this means the second curve selected. The position of the point in
selection order does not matter in angle-via-point.
[Sketcher] Fix wrong number for B-Spline tangent on redundancy
[Sketcher] Remove existing point-on-object in some redundant cases
Particularly when point constrained on a B-spline is being used for
tangent, perpendicular or angle via point with the same B-spline.
[Sketcher] Fix direction issue with B-spline tangents.
Without these changes the solver might try to "twist" the B-spline to make the
angle between curves be 0 instead of PI (which may be closer to the initial shape).
Fixes#11873 this was the primary goal of these changes
Fixes (partially) #11874 the parts of a polyline are combined as a
compound object (shape) but it would be preferable for them to be made
into a wire (if possible)
Fixes#11872 Objects in a block definition are now kept separately
until the block is inserted, in which case the inserted objects are
subject to all the other options regarding combining.
Fixes (partially, review required) #11871 Text and dimensions are now
kept as part of the block definition and are placed in the drawing when
the block is inserted but this code has not been extensively tested.
Affects #11875, custom types are not made, but the labels now reflect
the object types rather than all being "Shapennn"
This leaves the importer options handling in a bit of a mess that needs
cleanup eventually, but this can be a new issue.
This includes some importer flags that have no corresponding options
(e.g. import frozen layers), some flags not yet implemented, some
flags not yet even declared in the code because their implementation
is further off (import hatch outlines), and some suggested future
options (import SOLIDs as faces)
Centralize the calculation of the OCS for entities as they're read
from the DXF. Most of the entities don't use this yet, but some of
them roll their own crude Normal Vector handling. Because the new
code takes priority over the old for reading the normal vector, such
code will always see (0, 0, 1) as the extrusion direction.
Improves compatibility when using the legacy editor.
Corrects a number of issues that prevented saved files from being displayed when using the legacy editor.
Reduces the verbosity of console messages.
Some error messages would only work if objects were supplied as strings. These would fail if objects were passed (as objects) that had already been deleted.
The Draft_Wire command can combine selected Draft_Wires and Draft_Lines into a single wire. This function did not always behave properly.
* Edges were not sorted, the result could have a different shape (with the correct vertexes).
* If edges formed a closed shape the resultant wire was not closed.
These messages were perhaps originally intended as a debuggin aid but now add clutter to the output panes. Remaining messges are mostly the result of methods to display attributes of an object (which one could call from the Python console) or actually provide some information which would not be obvious from the circumstances
