With a 2 point bar, an A and B point are used to define the vector of the hidden point bar, and the hidden point (C) is con- structed along this vector at a prescribed distances from either the A or B points.
From the menu, select Construct>Points>Hidden Point Bar.
When prompted, select the A point.
Select the B point.
The Pick Hidden Point Bar dialog will appear. Select the ap- propriate hidden point bar, then click OK.
The Construct New Point dialog will appear. Specify the point name, leaving the coordinates alone—then click OK.
In the instrument name control type the <point name> $<Bar Index_0 for the point A (eg. “Point1$1_0”), and measure a point
Check that the name incremented correctly: <point name>
$<Bar Index_1 for point B (eg. “Point1$1_1”), and measure a point.
That’s it...Measure 2 points and it will compute the hidden point for you (eg. “Point1”)
