Select a draft object and a view on a drawing page, then the view created for
the draft object will have the same projection settings as the selected view.
- 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.

Remove redundant 3d vectors.

Elements that have internal geometry are created with the internal geometry on creation.
It has been under discussion for a long time. Ulrich was in favour (asked for it several times).
DeepSOIC implemented the focus because he hated the poor dragging of the ellipse when empty.

Fixes the bug that vertex far away got selected due to lack of sync between the selection and draw loops.

- The element to which internal alignment is applied has to be selected last.
- All other elements are added in the order of priority, taking into account existing elements
- Art by Jim (beautiful icons).
Sketcher New Feature: Tool to show/hide/restore the internal geometry of an element

toggles between hiding all unused internal geometry elements and showing all internal geometry.
The restore function is implicit to the showing all internal geometry
