=====================
New class allowing to define a VisualLayer:
- whether it is visible or not.
- the line width to be used by coin for this layer.
- the line pattern to be used by coin for this layer.
==============================================================================
In the Layers implementation there are User Layers, which have no direct impact on visualisation,
and allow to group conceptually related geometry into logical entities, and Visual Layers, which
define how geometries are visualised (or even whether they are visualised or not).
For User Layers, SketchObject is responsible for the definition of the layers, and SketcherGeometryExtension
is responsible for indicating the User Layer to which a geometry belongs (via a LayerId field).
For Visual Layers, ViewProviderSketch is responsible for the definition of the visual layers, and
ViewProviderSketchGeometryExtension is responsible for indicating the visual layer to which a geometry belongs.
With this commit, ViewProviderSketchGeometryExtension:
- takes over the responsibility of carrying a visual layer Id.
- is extended to be persistent and serialise the Id.
- is extended to be accesible from Python.
* If the compound contains solids then other shape types like faces or edges are ignored
* If the compound contains no solids but faces then edges are ignored
* If the compound contains no faces but edges then vertexes are ignored
While gears without a root fillet may have limited real-live use cases,
during number-input it happens regulary to have a zero fillet radius as
intermediate state. With this commit such a situation is now handled
gracefully.
Coverity CID 350580: Uninitialized scalar variable. The analyzer doesn't like the incomplete construction of the ConstraintId object (the 'Type' field was uninitialized).
==========================================
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
