Target layer: Polyline

Description:  Drag a line in the view. The start point of the selection line will be used for selection of the polyline from the target layer to be offset. The direction of the selection line will indicate the side in which the polyline will be offset. The user can set how outer corners between segments are handled in the  ET GeoTools control panel  (Polyline Tab). The settings are the same as in the standard ArcMap tool. The offset distance  can be set in the control panel or via a hot key while the tool is activated. In the control panel the user can set whether the offset distance dialog to appear for each operation or only when the hot key ("S") is pressed. In the latter case the offset distance assigned will be used by the tool until changed. 

The default action is "OFFSET - COPY". If the Shift key is pressed while selecting  - "OFFSET - MOVE"

Advantages: 

• Very efficient, no need of dialog to assign offset distance each time the tool is used
• No need for the user to figure out which is the left and which is the right side of the polyline in order to assign correct sign for the offset distance. This is done visually by the direction of the selection line.
• The parameters are set once and used by the tool until changed

Hot Keys (Pressing these keys when the tool is active will allow changing  the parameters used by the function): 

• "S" - allows adjusting the offset distance
• "SHIFT" - changes the action. If pressed - "OFFSET - MOVE" else "OFFSET - COPY"

Attribute Updates: The attributes of the original polyline will be preserved
