Open the COGO page.

Select Alignment & offset.

Select the reference element.

Reference.

• Line (2 points): line defined by two topographic points. Requires to select Point 1 and Point 2.

• Arc (3 points): arc defined by three topographic points. Requires to select Point 1, Point 2 and Point 3.

• Arc (2 points+R): arc defined by two topographic points and by the radius. Requires to select Point 1, Point 2 and arc radius.

• Drawing object: select a line, polyline, arc or circle in the graphic window.

Press Invert to invert the reference direction.

Press Info to have information on the reference object.

After the reference object has been selected press Next to define the parameters.

• Distance along reference: distance at which the point is located along the reference element.

• Offset: lateral distance at which the point is located referring to the reference element.

• Height difference: elevation difference to apply to the interpolated elevation of the point.

Press Next to proceed.

The software shows the result of the calculated point.

Press Create point to create the point in the topographic points list.

Press Stakeout to stakeout the point.
