==========================================
Extend ViewProviderGridExtension so that it is aware of the absolute direction of the XY plane on which the grid is to be drawn.
Fix the calculation of the cam origin.
Sketcher/Grid: fix algorithm computing the automatic grid spacing
Sketcher/Grid: forcefully redraw grid when one of its parameter is changed
Sketcher/Grid: always authorize user to change grid spacing, even if 'auto spacing' is enabled
Sketcher/Grid: apply a default factor of 10 for 'auto spacing' if number of subdivision is 1
===============================================
Removal of ViewProviderGridExtension properties:
-GridStyle
-GridSnap
Improvement of ViewProviderGridExtension API:
- color via App::Color
Toolbar grid command:
- Conversion of Snapping to edit parameter
- Snap gets a class enum to support future Snapping functionalities as edit parameter
Sketcher Settings:
- Removal of snap preference
Behaviour:
- ShowGrid, GridAuto, GridSize preferences do not change any existing VP. They apply to any newly created sketch.
- Do not limit grid to hardcoded values
Snap to grid:
- Code updated to use closestpoint functionality provided by the extension,
Several other fixes
==================================
- Move all grid specific code out of ViewProviderSketch and EditModeCoinManager.
- The code in made into a new extension in Part - ViewProviderGridExtension
- ViewProviderSketch starts deriving from this new extension
- ViewProviderSketch configures the extension according to its Grid preferences
- Grid code refactored to remove hardcoded sketcher preference parameters.
- ViewProviderGridExtension handles property name/type changes within its competence.
- it is a well-known and often feed-backed missing feature that SectionCuttings fails for intersecting objects.
To resolve this, the objects must be put int a BooleanFragments object.
- this PR adds this functionality as option.
- since a BooleanFragments objects has a specific color, the different colors of the objects cannot be preserved. Because of this disadvantage, the BooleanFragments option will not be the default.
- this PR also modernize all for loops
Mesh generation parameters are taken from PrusaSlicer's STEP importer,
which does a just-in-time STEP->STL conversion in memory.
Resulting meshes have better geometry, but are a little larger as a result.
- a typical use-case is to open a document with an existing cut and only this cut is visible. When now opening the section cutting tool, the user got the fault message that there were no visible objects to be cut.
- the transparency for the cut was not explicitly set. Therefore the default transparency for new objects was used instead of the transparency of the objects to be cut.
- workaround for a graphics issue: when cutting objects intersection each other (only then), the transparency setting might be ignored. The fix is simply to change the default color slightly (By the way, this issue is independent on the color that is set in the Part preferences as color for new objects, seems to be a graphics driver or OCC issue.)
- besides this, avoid code duplication by using a lambda function
When `v == u` we want to "break" the b-spline at `u` (also OCC will raise an
exception if same parameter is provided).
The range of parameter can in general be different than 1.0, so use a general term.
