Editing Polylines and Polygons

Water body polygons and retouch polygons and polylines are edited using the commands in the mini toolbar. This toolbar is displayed whenever the polygon/polyline is selected.

To edit a polygon/polyline:

1.     Select the polygon/polyline, and then do either of the following:

§  Move the polygon/polyline

§  Modify the polygon/polyline shape

2.     If you want to select a different object from the one currently being edited, click Select another object .

3.     If you want to align your polygon/polyline to a surface, click Align to Surface . The polyline/polygon's nodes are aligned to the surface.

To move a polygon/polyline:

1.     Click the Edit Object icon A picture containing gauge, object Description generated with high confidence.

2.     Do any of the following:

§  If you want to set position based on mouse and snap the polygon/polyline to another object, click Snap Based on Snapping Options icon  (Shortcut key: 4). See "Setting Snapping Options" in this chapter for information.

§  If you want to set position based on mouse without snapping the polyline/polygon to another object, click Set Position Based on Mouse A close up of a logo Description generated with high confidence (Shortcut key: 3).

§  If you want to move polygon/polyline in the XY plane, click XY Plane A star in the background Description generated with high confidence.

§  If you want to move the polygon/polyline in the Z plane, click Z Axis A picture containing object Description generated with high confidence.

3.     Click the polygon/polyline, and drag it to the required location/altitude. Release the left mouse button to set the polygon/polyline at the current location/altitude. If snapping to an object, move and snap the polygon/polyline to an edge or vertex of any existing object.

To modify a polygon/polyline's shape by moving its nodes:

1.     Click Edit Nodes .

2.     Do any of the following:

§  If you want to set position based on mouse and snap the polygon/polyline to another object, click Snap Based on Snapping Options icon  (Shortcut key: 4). See "Setting Snapping Options" in this chapter for information.

§  If you want to set position based on mouse without snapping the polygon/polyline to another object, click Set Position Based on Mouse A close up of a logo Description generated with high confidence (Shortcut key: 3).

§  If you want to move a node in the XY plane, click XY Plane A star in the background Description generated with high confidence.

§  If you want to move a node in the Z plane, click Z Axis A picture containing object Description generated with high confidence.

3.     In the 3D Window, place the cursor over one of the polyline/polygon’s nodes. The node turns blue.

4.     Click the node and drag it to the required location in the XY/Z Plane. Release the mouse button to set the node at the current location.
