If it is a linear dimension show the older icon;
if it is a radius or diameter dimension show a new icon.
These three modes use the same Proxy class
and the same viewprovider class. Depending on the linked geometry
one icon or the other will be shown.
When there are many Draft objects in the tree view
the icon can be used to tell different objects apart quickly.
One icon is used for objects that are "straight lines",
whose Proxy is of type `Line`, `Wire` or `Polyline`; another icon
for "regular geometrical" shapes of type `Rectangle` or `Polygon`;
and another icon for "curved" objects of type `Circle`,
`Ellipse`, `BSpline`, `BezCurve`, or `Fillet`.
Other objects use the older default icon.
It replaces the older `Draft_Array` command, and provides
a task panel to select the properties, similar to the
`Draft_PolarArray` and `Draft_CircularArray` commands.
It can also create `App::Links` directly from this task
panel, so it also replaces the `Draft_LinkArray`
introduced by the LinkMerge.
The linear and radial dimensions use the same Proxy class,
but the angular dimension uses a different Proxy class.
To recognize quickly in the tree view the different
types of dimensions, we provide a new icon.
The icon is inspired on the `Draft_Dimension.svg` and
`TechDraw_AngleDimensions.svg` icons.
* Add Draft_LinkArray and Draft_PathLinkArray that uses link for both
data and visualization, which supports linking external objects
* Add link group support for draft snap
* Fix ArchWindows expression ambiguity
* Remove Arch option to snap to wall base (reimplemented below)
* Added new Specials snap button
* Special snap snaps to wall baselines, structure basepoints, and contents of SnapPoints property, if existing
Draft: allow continuity on closed Bezier curves
Draft: BezCurve bugfixes
- smoothBezCurve
- edit mode
- avoid splitting points into segments as long as degree is zero
- increase the continuity when closing curve
- closed berzier curves
- Catch modifications of continuity of first and last knot on open curves
