Feature Description

Rotates selected objects when the layer is editable.

• Rotation Anchor Point and Center

  The rotation anchor point is the top-left corner of the geometry's bounding box. The center (marked with an X shape as shown below) locates inside the geometry. During rotation, the anchor point remains stationary while the geometry rotates around the center at specified angles.

  When multiple objects are selected, the rotation anchor point becomes the top-left corner of their collective bounding box.

  

• SuperMap supports rotation for objects in point layers, line layers, polygon layers, text layers, CAD layers, and route layers.
• Rotation can be performed either by dragging the rotation handle to desired positions, or by manually entering precise rotation angles.

Feature Entry

• Features Tab -> Feature Editing Group dropdown -> Rotation.

Steps

Drag Rotation

1. Select one or multiple objects in an editable layer.
2. Position the cursor over the rotation handle. When the cursor changes to rotation state, press and hold the left mouse button to drag objects to target positions, then release the button.

Precise Rotation

1. Select one or multiple objects in an editable layer.
2. Click the Rotation button in the Gallery control of Feature Editing group under Features tab to open the Rotation Settings dialog.
3. The center coordinates (X,Y) are displayed. By default, the center is the midpoint of the geometry's bounding box. Users can modify coordinates directly or click the Coordinate Pickup Rotation Center Point button to set new rotation center.
4. Enter rotation angle in the input box. Positive values rotate counterclockwise while negative values rotate clockwise. Preview of rotated geometry (shown with dashed lines) updates in real-time.

   

5. Click OK to apply rotation to selected geometries.
