2 Point Hidden-Point Bar

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.

To Construct a Hidden Point:

  1. From the menu, select Construct>Points>Hidden Point Bar.

  2. When prompted, select the A point.

  3. Select the B point.

  4. The Pick Hidden Point Bar dialog will appear. Select the ap- propriate hidden point bar, then click OK.

  5. The Construct New Point dialog will appear. Specify the point name, leaving the coordinates alone—then click OK.

To Measure a Hidden Point:

  1. In the instrument name control type the <point name> $<Bar Index_0 for the point A (eg. “Point1$1_0”), and measure a point

  2. 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”)
