Stakeout Using a
Reference Arc
1. When everything is set up correctly (see Station Setup on
page 19), tap Arc from the Layout menu.
2. Define the reference arc or select an existing one from the
plan, using one of the four options below.
• Two points on the arc & radius (see diagram [1]): Select
the start (P1) and end (P1) points from the plan, key
in the radius (R) and choose the short (A) or long (B)
section.
• Three points on the arc (see diagram [2]): Select the start
(P1), arc (P2) and end (P3) points from the plan.
• Center point & a point on the arc (see diagram [3]): Select
the center point (P1) and arc point (P2) from the plan.
This option defines a full circle. P2 is the start of the
arc and the direction of the arc is clockwise.
• Select existing arc (see diagram [4]): Select an existing
arc from the plan. Both the arc and the points defining
the arc will be selected together.
Tap Next after making a choice and follow the instructions
until the reference arc definition is complete (see example
below).
