Rotation

Function Description

Rotates the selected objects when the layer is editable.

  • Rotation Anchor Point and Center

    The rotation anchor point is the corner point at the top-left of the geometry's bounding rectangle. The center is located inside the geometry (in an 'X' shape, as shown below). During rotation, the rotation anchor point remains fixed, and the geometry rotates around the center by the specified angle.

    When multiple objects are selected at once, the rotation anchor point is the top-left corner of the common bounding rectangle of these objects.

  • SuperMap supports rotating objects in point layers, line layers, region layers, text layers, CAD layers, and route layers.
  • During rotation, you can either drag the rotation handle to rotate the object to the target position or manually enter a rotation angle for precise rotation of the geometry.

Operation Instructions

Drag to Rotate

  1. Select one or multiple objects in an editable layer.
  2. Place the mouse pointer over the rotation handle. When the cursor changes to indicate rotation, press and hold the left mouse button, drag the object to the desired rotation position, and then release the mouse button.

Precise Rotation

  1. Select one or multiple objects in an editable layer.
  2. In the General editing drop-down menu on the Edit Data tab, click the Rotation button in the Move and zoom group to open the Rotation Settings dialog box.
  3. The center point lists its (X, Y) coordinate values. The default center point is the center of the geometry's bounding rectangle. You can set a new rotation center point by modifying the (X, Y) coordinates or by using the Coordinate Pickup Rotation center point button.
  4. Enter the rotation angle in the rotation angle edit box. A positive value rotates the object counterclockwise, and a negative value rotates it clockwise. After entering the angle, the map will display a real-time preview of the rotated object (shown with a dashed line).

  5. Click the OK button to rotate the selected geometry.
