Marker Transformations
This section explains how different transformations behave with several markers.
When several markers are selected and you drag a marker's handle, the respective transformation is applied only to the selected markers containing the same type of handle. An exception to this is point handles which only affect the marker attached to the manipulated handle.
The following transformations can be applied to several markers, simultaneously:
Rotation
The rotation is applied from the centre of every marker eligible for rotation. The rotation angle of the manipulated marker is also applied to all the selected markers that are eligible for rotation.
For information on the rotation snap, see Rotation Snap.
Scaling
The scaling is applied from the opposite corner of the selected handle group regardless of the rotation of the marker. The proportional scale is also applied to all the other selected markers eligible for scaling.
You can scale the markers from their centers by pressing the Ctrl while dragging the handle.
You can scale the marker with a fixed aspect ratio, by pressing the Shift after dragging the handle.
You can combine the above two behaviors by pressing the Ctrl and the Shift simultaneously. The markers are scaled from the center and the aspect ratio is locked.
Radius
The proportional radius transformation is applied to all the selected circle markers.
Position
The position of several markers are changed with respect to the manipulated marker.
You can move the markers only in the direction of the horizontal and vertical axes by pressing the Shift before dragging the handle.
By default, the position handle is snapped to the manipulation grid. For more
information on the manipulation grid, see Manipulation Grid.
Point Position
This transformation changes the position of a point.
If the handle is snapped, the representations of its axes are displayed. These representations vanish once the dragging is finished.
Marker Representation Translation
You can move the marker by dragging its representation even when the marker is not selected.
If the geometry of a non-selected marker is dragged and the Ctrl is not pressed, all others markers are deselected.
If the Shift key is pressed, the markers can be moved only in the direction of the vertical or horizontal axis of the screen. Two dotted lines are displayed representing these axes.
Duplication
If the Ctrl key is pressed during the representation manipulation, the selected markers are duplicated and moved. If the Ctrl is released during the transformation, the duplicated markers vanish.
To keep the duplicated markers, keep the Ctrl key pressed until the manipulation is finished. At the end of the manipulation, only the original markers remain selected.
