This fixes issue:
http://www.freecadweb.org/tracker/view.php?id=2281
Discussed in:
http://forum.freecadweb.org/viewtopic.php?p=101910#p101910
How to reproduce?
With Auto-Update mode unchecked, execute the sequence in the bug tracker. You will reach to a geometry assembly successfully solved that can not be moved.
Why?
The coincident constraint is partially redundant within the meaning of redundancy of the solver.
The solve within "addconstraint" in SketchObjectPy.cpp causes the geometry to move to meet the coincident constraint.
At the end of the solve, the initial solution used in diagnostics is no longer valid (the geometry moved). This causes a subsequente move not to be executed.
The Solution:
Recalculate just the initial solution after the addition.
=====================================
When the solver converged (but did not succeed) or when the solver succeded but the solution is not OCC-valid, no error message was shown in the solver messages dialog.
To run frequency analysis user have 2 options:
1. Run normal aalysis, set "frequency" and start ccx
2. Set Analysis Type in Analysis object properties to "frequency" and
use Quick Analysis
With that workflow we no longer need a separate button for frequency
analysis. Also it's much easier to prepare & run a dediacted analysis
for frequency calculiations and separate analysis objects for
different load cases.
FemCommand class will gather all common functions/propertied od FEM gui
commands. That should allow to reduce some common code.

Issue:

Constraints dissapear after a sketch loses support
Steps To Reproduce:
1. Make a sketch on a face.
2. Constrain it
3. Select "reorient sketch"
4. Do you want to lose support? Yes
5. Click cancel on the reorientation dialog.
6. Enter edit mode: No constraints...
Why?
GeoUndef not checked when deleting all external geometry (on dettaching from the support).
Solution:
Check for GeoUndef.
+ add method to make image view unclosable for user
+ fix possible crash in MeshAlgorithm::GetMeshBorder
+ fix possible crash in MeshAlgorithm::ConnectLines
===================================================
The bug was introduced by myself here:
47c0859c1b
[code]
void SketchObject::onDocumentRestored()
{
try {
- rebuildExternalGeometry();
+ if(Support.getValue()) {
+ validateExternalLinks();
+ rebuildExternalGeometry();
+ }
Constraints.acceptGeometry(getCompleteGeometry());
}
[/code]
The issue is that "rebuildExternalGeometry" calls "rebuildVertexIndex". So for any sketch not having external geometry, if you open it, select everything and hit del, you will have a crash because
I effectively removed the creation of the index in this dossier. You won't have one if you do anything rebuilding the index before hitting del, like creating geometry, though.
================================================
Issue reported inter alia here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12380#p99456
How to reproduce:
1. Make an external geometry hexagon (make a hexagon, pad it, make a sketch on a hexagonal face and make all the lines external geometry)
2. Box select the external lines and press "del"
On the first pressing of "del" 3 lines were deleted and 3 remained, select again, on the second press 1 remains, select again, on the last press all are deleted.
Why?
Internal and External geometry were handled together in a single set. Group deletion of geometry is effected starting from the highest index,
so that upon deleting an element, the index of the remaining elements does not change. Handling both groups together caused that the external geometry
was actually deleted on the inversed order (as they are (decreasing) negative values for representation, but increasing positive indexes in the external geometry array).
Solution:
Internal and External geometries are handled separatedly

=================================================================
First bug: Inability to create links to external geometry as described here:
http://forum.freecadweb.org/download/file.php?id=16668
Second bug: FC crashes on changing the support after having imported external geometry as described here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12380
and solving this ticket:
http://www.freecadweb.org/tracker/view.php?id=2225
Solution to first bug:
If for some reason a sketch ends up having a list of external geometries (property) that can not be recreated (rebuilt),
they remain latent, do not show the external elements in the elements widget or in the screen and prevent adding the
elements again.
In cases where the saved file contains invalid external geometry links (which will give raise to a handled exception that would prevent external geometry creation),
this condition gets detected during restore and the invalid links are deleted before external geometry creation, so as to allow the rest of external links to be recreated.
Solution to second bug:
It is also related to invalid external links (the link was existing, but upon change on the support, it is possible that an external edge is no longer valid, reduction of edges in support).
This situation is detected upon entering into edit mode, and the invalid ones are deleted.
Note that there is still the possibility for the user to remap an invalid sketch BEFORE editing, if the remapping is successful, it may not be necessary to delete links (all depends on the
specific case).
Since getTypeName() returns None for None and default both must be handled the same way in other switches.
After applying following bug will be fixed:

==============================================================================
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.
======================================================================
1. SketchObject::arePointsCoincident upgraded to check for indirect coincidence.
2. Coincidence constraint creation now checks for indirect coincidences and avoids
creating redundant coincidence constraints (for example during box selection).
=====================================================================================
This fixes a bug related to:
http://www.freecadweb.org/tracker/view.php?id=2093
that during creation of a geometric element if a vertical/horiz autoconstraint is to be enforced, it is not enforced if the endpoints of the geometric element under creation are
coincident with external geometry.
According to the discussion here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12254&sid=eacf5bdee068cb71cc54dc5a62a6849d&start=20#p99359
this fixes the bug.
It does not fulfil the request on the ticket as it was decided to still allow an explicit addition of a vertical/horizontal constraint, as
it may be needed in some cases and the user expects to be able to add them, even if it will lead to an overconstrained sketch.
How to reproduce?
1. Create a rectange
2. Pad it
3. Create a new sketch on a face
4. link two corners as "external geometry" (but not the ones of a diagonal)
5. Create a line coincident with the first and second corners, so that the line is horizontal or vertical
In master it will force horiz or vert leading to a overconstrained sketch.
With this patch, the horiz/vert will not be enforced in this case.
==================================================================
A recent improvement was to allow to create an object (several geometric elements) as construction lines
by providing an additional parameter as true (that defaults to false).
This introduced a bug, that when a list of geometries mixing construction and normal lines was added (with the parameter as false),
construction lines would be converted to normal lines.
This fixes the bug.
===============================================
Support for mirroring a full sketch.
A dialog appears allowing to select X, Y axis mirroring or mirroring about the origin of the sketch.
=========================================================
This commit provides with a single toolbar button to select between a copy and clone.
Copy just copies the constraints.
Clone modifies the dimensional constraints to geometric constraints, so that the constrained geometry follows the changes in the original object.
=============================================================
This commit allows the user to select in advance whether he wants a simple copy or a clone.
This involves substitution of dimensional constraints in the copies by equality and parallel constraints.
Terminology change for Arrays, now it is Rectangular array
==========================================================
- Support for copying geometric elements in the sketcher with Ctrl+C (or using the still missing icon). It will show you the vector of displacement from the
"reference point". The reference point can be chosen by the user (although it is not necessary to do it so) by making the point the user wish to be the reference point
the last selected element. It conveniently incorporates "autoconstraints", so that you can make this point (the one of the copy) directly coincident with any other point in the sketch.
- Python 2D array command modified to lock elements position using construction lines and constraints.
- Support for different spacing between u and v directions (the direction of the cols and the direction of the rows).
- Support to avoid copying DistanceX and DistanceY constraints when used for locking a point. This means that if the geometry that you copy(array) is
fully constraint, the resulting 2D array is also fully constraint.
- UI support for creating 2D linear arrays in the sketcher.
- Bug fix in python addArray, wrong line copy startingpoint calculation fixed.
How to create a 2D array in the sketcher:
1. Select your geometric elements.
2. Click the button
3. Fill in the rows/cols and preferences on spacing and constraining each element of the array
4. Click Ok
5. Define the direction of the cols of the array and click
========================================================
For a while End-to-endpoint tangency is implemented via AngleViaPoint constraint. The code was not recalculating the "value" of the constraint in this case.
This also forces to set the geometry first and constraints afterwards, as the AutoLockTangencyAndPerpty function requires a valid GeoId to operate (not a big deal anyway).
Correction of the condition to allow the symmetry when a single line is mirrored about a point pertaining to a geometric element.
======================================================
Two new python commands (no UI yet).
Copy: Copies the geoids in a list by a displacement given by a Vector3d:
App.ActiveDocument.Sketch001.addCopy([0,1,2,3,4,5],App.Vector(150,150,0))
Array: Copies the geoids in a list cols times in the displacement vector
direction and rows times in the perpendicular to the displacement vector:
App.ActiveDocument.Sketch001.addArray([0,1,2,3,4,5], App.Vector(150,150,0),3,4)
N.B.: You need to recompute or solve to update the view
App.ActiveDocument.recompute()
or
App.ActiveDocument.Sketch001.solve()
=====================================
Creates geometry symmetric to the selected one with respect to the last selected point or line.
It does not support the following constraints:
- Angle
- Horiz/vertical distance
- SnellLaw
Horizontal and Vertical (directional) dimensions removed from the the copying process when created
on a single edge (by picking one edge instead of two points), i.e. Constraint involving only one GeoId at "First".
