Hidden-Point Bar Database

Hidden Point Measurements Overview

It is often necessary to be able to take measurements and compute point location is in places that cannot be directly reached or measured. Hidden-Point Bar definitions provide a means to do that. Hid- den points can be computed in two ways:

Re Computation

Hidden point positions are dynamic. The naming convention can be used to compute an offset point and this happens automatically when points with the given name are a measured from an instrument. There is also a button to trigger an update for all hidden point bar definitions in a job file that can be found on the instrument tab under Instrument Shots:

 

Dialog Controls

The Hidden-Point Bar Database offers a list of hidden point bar definitions. A single default 2 point bar is available as a reference only. Use the Edit and Delete buttons to edit or remove the selected bar.

The list of Hidden Point bars can be Imported or Exported as needed using an XML format.

 

Types of Hidden Point Measurements:

Bars can be defined in either of three ways through the buttons at the top right of the dialog:

 

Automatic Hidden Point Computation

The most effective way to use hidden point bars or fixtures is to use a naming convention to designate points as part of a defined hidden point bar or fixture. To do so follow this naming convention:

Point Name $ (Bar Index) _ (Point Index)

If this naming convention is followed hidden point locations can be updated/recomputed at any point by using the menu command Analysis>Re-Compute Hidden Points. This can be quite helpful if hidden points are computed from multiple instrument plants and their relative positions are changed do to an alignment.
