- Rebase App::Origin on App::DocumentObject
- Keep all control over the Origin structure inside the Origin and it's
ViewProvider
- Add OriginFeature class as common base for App::Plane and App::Line
- Rebase App::Plane and App::Line on top of newly created class and
move to the file.
- Change Origin's ViewProvider API associated with temporary display
- Lots of associated changes to files
- Several minor fixes
- Lots of new bugs
==============================================================================
What is this?
method
getCoincidentPoints
actually only included (as indicated in the documentation comment) those points coincident by a single constraint.
That is not "all the coincident points".
However some methods currently using it are expecting exactly that (coincident points linked by a single constraint).
A new method is introduced:
const std::map<int, Sketcher::PointPos> getAllCoincidentPoints(int GeoId, PointPos PosId);
that provides all the points coincident with the given one, directly (via a single constraint) or indirectly (via multiple coincident constraints).
The old method is renamed to:
getDirectlyCoincidentPoints
So as to have a more meaningful name to differentiate between both methods.
======================
In no update mode, the last constraint was not enforced. The DoF was not properly shown.
The trim operation it is always solved at the end now if in no recompute mode.
================================================================
A last moment change to regulate redrawing introduced this issue (reducing the redrawing to the cases where the solver geometry and the sketchObject geometry are equal).
This change also solved other issues.
The case of adding external geometry is special because the DoF is the same after insertion, yet there is an insertion (as opposed to the toggle case, where there is a change but no insertion).
SketchObject has been adapted to require a solver update before moving (which also caused a non-yet-reported crash, a separate bug), and CommandCreateGeo has been adapted to trigger a solve with
auto update mode disabled. This solve is a very low cost one as the geometry is already in place.
===============================================================================================
Group creation:
- complex geometries (consisting of several geometry elements and constraints) have been rewritten to use python list (one command call for all geometries and constraints)
- Ellipse ExposeInternalGeo as group creation of geometries and constraints
To construction mode creation:
- addGeometry python and SketchObject functions modified to take an additional optional parameter "construction" to create the geometry/geometries directly as construction.
In addition to the shorter form, this helps generate less amount of onChange propagation and Redraws.
- all the geometry creation commands in CommandCreateGeo.cpp have been rewritten to use the new construction argument. This includes modifying the regular polygon script to
take a new optional parameter to create geometry as construction in addGeometry.
- special care is taken in group creation not make construction points
- Show/hide internal geometry implemented with this option.
To solving:
- the solve previously included after every geometry addition (when in no Update, e.i. no Recompute mode) has been removed and each Gui::Command calls either an UpdateActive
for recompute or a Solve in no Update mode. This is behaviour is less intrusive and uniform with group creation.
Bug fixes and redrawing reduction:
- Fixes the CheckId exception problem. The solution also helps further remove redraws during creation of complex geometry (e.g. Slot)
- Fixes touching the sketch by only opening it.
- Code clean up.
=======================================
- Fixing toggle AutoUpdate Mode
- Fix Auto-Update Sketcher tools
- Fix missing createGeo recomputes
- Missing constraints recomputes fixed
Various fixes for non-Update mode:
- Fixes lack of update upon entering a conflicting datum constraint.
- Fixes lack of update upon setting the reference/driving status of a constraint
- Added tooltips to buttons
======================================================================================
There is a checkbox, default disabled, that makes the commands NOT to generate a recompute after each.
This means that if you are editing a sketch that is used to generate a pad or pocket, if the checkbox is
disabled, the dependent objects do not get recomputed.
There is a button next to it to force a manual recompute, in case it is needed.
If the user wants the previous behavior, he only needs to activate the checkbox. The previous status of the box
is restored upon entering a sketch in edit mode.
It is remarkable the case of the Fillet and Trim
On changing ActSketch (solvedSketch) to SketchObject and making movePoint not systematically update the geometry, the solving in MovePoint was confronted with solving for "the last solved geometry",
which is the default behaviour, in some situations (Fillet and Trim) where geometry had changed at SketchObject level, and was the subject of the moving actions.
MovePoint has been updated to take an extra optional parameter, to force the change in solved geometry in those situations.
Some other minor bug also fixed in Fillet creation in CommandCreateGeo.cpp
This commit also introduces conditional recompute on some operations of:
- constraints
- geometry creation (reubication of update active to comprise the autoconstraints within a single UpdateActive)
==============================================================================
Now you can switch from one tool to the next just by clicking on the next tool
==================================================================================
Geometry button:
- if no object selected, the legacy toggle icon has a new functionality, switch to/from creating in construction mode
- if object selected, it has the legacy functionality
- the button can be clicked during "continuos creation mode" to switch from creating to/from creating in construction mode
Constraint button:
- The button is not selectable if nothing is selected (it would be impossible to determine the effect)
- When constraints are selected, the button toggles the constraints to/from Driving.
- When geometry is selected, the button switches from/to reference mode, the change is apparent from the color of the constraint icons.
Continuous creation mode:
- Default changed so that it is active unless you change it in settings
Updated terminology
======================================================================
- Changing from Driving to reference does not include unnecessary solvings.
- Added some checks to avoid making Driving constraints when calling directly from python and involving only external geometry (would give redundant constraints).
- New python command toggleDriving to just change the status from reference to Driving
- New UI toolbar Command to toggle constraints
- Fix to allow switching from/to construction mode during continuous mode creation.
- Enable/Disable for constraints in constraints widget has changed to operate on multiselection and now effects "toggle" instead of enable/disable.
- Disable the option to directly create a SnellsLaw non-driving constraint (this constraint does not support direct creation, it can be toggled to non-driving after creation though).
==============================================
The fillet applied to construction lines generates normal (not construction) geometry.
How to replicate?
1.Make a square and make all lines construction lines.
2.Apply fillet tool, there result will be a white line fillet connecting two blue constructions lines.
===============================================
It allows to select whether the geometry will be created as construction geometry or normal geometry.
This commit includes an important bug fix to reduce the number of times the sketcher solver is called when toggling
geometry. It makes an important difference in the creation during construction mode and InternalAligment geometry like the ellipse.
This commit does not include icons.
You have a button next to toggle that after having been clicked, switches from Normal to Construction geometry and vice versa
============================================================
It lifts the need of clicking on the external geometry icon upon importing each external geometry element.
All the elements on which the user clicks are imported until the user right clicks with the mouse or presses ESC, like the Trim or Fillet tools.
===============================================
When creating a type of geometric element, the user can create as many elements of that type he wishes without having to click the button before each insertion.
The insertion of that type of elements ends by pressing ESC or clicking the right button of the mouse.
This mode is by default disabled and can be enabled in Preferences->Display->Sketch->Geometry Creation "Continue Mode".
=========================================
The autoconstraints on creation of an hexagon were not working.
How to reproduce?
1. In a sketch make a couple of lines
2. Create an hexagon (or other polygon of your choice) with center in one end of a line and with side coincident with the end point of the other line
Result:
Neither the center nor the side autoconstraints are properly created.
Fix:
Straightforward. Just correct the indexes. Last is always the circle. Last but one is always a side.
Fixes a bug where an arc, ellipse, or arc-of-ellipse, being reversed in
XY plane, behaved badly in sketcher (see forum thread "Sketch: how to
handle reversed external arcs?"
http://forum.freecadweb.org/viewtopic.php?f=10&t=9130 ).
Also fixes a problem with rotated arcs (see forum thread "Rotating Arc
in Sketcher"
http://forum.freecadweb.org/viewtopic.php?f=22&t=9145#p74262 ).
This is done by adding an emulation flag to a few methods in
Part::GeomXXX, which makes the shape to pretend being non-reversed
(CCW). This causes endpoints of reversed arcs of circles lineked as
external geometry to swap, causing broken sketches sometimes.
- ArcOfEllipse enhancement: Tangency ArcOfEllipse to ArcOfEllipse or ArcOfCircle by selecting end/starting points...
- Minor bug corrections (Thanks DeepSOIC)
- ExposeInternalGeometry python command
- DeleteUnusedInternalGeometry python command
- On deletion of an Ellipse/ArcOfEllipse all further unconstrained internal geometry is also deleted.
- This cleans up the code by eliminating code repetition in the creation methods.
- Major bug fix for autoconstraints for ellipse and arc of ellipse creation (for both creation methods)
- Major bug fix Start and Endpoint constraints of an arc of ellipse where not taking into account that Sketcher arcs are always CCW, so they have to be exchanged if we convert a CW arc into a CCW arc.
Sketcher: General bug fix: Tangency wrongly suggested
What?
=====
- On creation of a shape autoconstraints are suggested.
- Tangent autoconstraint was suggested even with lines perpendicular to the tangency direction
Reproduce
=========
- Make a circle on the origin and move the mouse along the X axis, it will suggest a tangency that is impossible
- Click on the axis and no circle will be created
Solution
========
- The SeekConstraint now can use the parameter dir to give a direction that is substantially perpendicular to the expected tangency, so that
if an object having a direction (a line) is hit, a tangency will not be suggested if within around 6 degrees of being parallel.
- Additionally, if such a line is an X,Y axis of the sketch, tangency will only be suggested if the direction is within 6 degrees of being perpendicular (i.e. it is almost tangent already while sketching).
- This difference is due to the fact that an X or Y axis can not "move" to meet the object under creation, whereas a line can.
I. Fix minor bug where wrong b was used to create ellipse internal geometry.
Tweak the internal geometry code a bit and reformat it so it isn't so wide.
Also begin debugging constraint conflicts on small circular ellipses.
There seem to be two issues currently in major/minor internal geometry lines:
1) Sometimes minorLength > majorLength due to round-tripping doubles, and
2) Constraint conflicts when majorLength > minorLength by an epsilon on the order of 1e-6
(cherry picked from commit 5c3e20af1a95c860112289dcdda54ea99778bc3a)
II. When testing for a valid ellipse, also ensure that the mangled major axis length > the mangled axis length.
This additional condition ensures that major and minor axis constraints don't conflict in the case of small
(nearly) circular ellipses.
The is still a potential bug in the solver when the major length is just slightly larger than the minor, but this fix
makes it nigh impossible to reproduce.
(cherry picked from commit 7e274bc32d9aa1a12ab52bfa33ed80353540b062)
III. Code clean up
Remove redundant 3d vectors.
