Описание

The TechDraw LeaderLine tool adds a line to a View. Other annotation objects (such as Rich Text Annotations) can be connected to the leaderline to form complex annotations.

Leaderline added to a View

1. Select a View.
2. There are several ways to invoke the tool:
   • Press the Add Leaderline to View button.
   • Select the TechDraw → Add Lines → Add Leaderline to View option from the menu.
3. A task panel opens.
4. Press the Pick points button.
5. Pick the first point on the page to define the start point of the line.
6. Pick the next point on the page. Hold down Ctrl to snap to multiples of 22.5° angles. Optionally use a double-click instead of a single-click to finish entering points.
7. Optionally add more points.
8. If you have not double-clicked a point: press the Save Points button.
9. Optionally change the Start Symbol, End Symbol, Color, Width and Style of the leader. See Properties for more information.
10. Press the OK button.

Usage edit

1. Double-click a Leaderline in the Tree view.
2. A task panel opens.
3. To edit the points:
   1. Press the Edit points button.
   2. The Leaderline is marked with temporary nodes.
   3. Drag one or more of the nodes to a new position.
   4. Press the Save changes button.
4. Optionally change the Start Symbol, End Symbol, Color, Width and Style of the leader. See Properties for more information.
5. Press the OK button.

Notes

• You cannot add or remove points from an existing Leaderline.
• If no points were specified at creation time a short line is placed at the center of the View. There is no way to fix such a line, it should be deleted.
• By default the Leader Line Auto Horizontal preference is checked. This means that the last line segment of new Leaderlines is drawn horizontally. If there is only one segment the result is then a single horizontal line.
• You can turn off this auto horizontal feature for existing Leaderlines by changing their ДанныеAuto Horizontal property.

Программирование

The LeaderLine tool can be used in macros and from the Python console by using the following functions:

myPage = FreeCAD.ActiveDocument().Page
myBase = FreeCAD.ActiveDocument().View
leaderObj = FreeCAD.ActiveDocument.addObject('TechDraw::DrawLeaderLine','DrawLeaderLine')
FreeCAD.activeDocument().myPage.addView(leaderObj)
FreeCAD.activeDocument().leaderObj.LeaderParent = myBase
#first waypoint is always (0,0,0)  
#rest of waypoints are positions relative to (0,0,0)
leaderObj.WayPoints = [p0,p1,p2]
leaderObj.X = 5
leaderObj.Y = 5
