You can isolate a gross error using the fit and zero options within the automet analysis section.
=== Bolted up ===
automet® FAB automatically assigns the '''Bolted up''' condition when the calculated distance between the diameter-point plane ('''D''') and the stop point ('''S''') matches a two-flange joint thickness. Operators can manually uncheck this setting if a single heavy flange is misidentified.


See the video on this topic here:

=== Ignore length ===
Enabling '''Ignore length''' removes the axial length vector from best-fit mathematical constraints:
* '''Open pipe ends:''' By default, open pipe ends are set to ignore length, allowing for excess material without distorting overall spool alignment.
* '''Custom configuration:''' Any flange can be configured to ignore length, or open pipe ends configured to enforce length, depending on site requirements.


By default, automet will average out the error on all flanges and give you the best-fit option. All surveyed data points have been fitted to the design using a method known as least-squares averaging. Importantly, '''this method masks gross errors'''. We can use the option to drop a flange from the fit to show us where gross errors are located.
=== Fit preference ===
The '''Fit preference''' slider controls the mathematical weighting applied during best-fit routines:
* '''Position:''' Prioritises reducing vector location errors (black arrows).
* '''Alignment:''' Prioritises reducing flange face angular touchpoint errors (gold values).
* '''Reset to defaults:''' Pressing '''Reset to defaults''' restores original parameters without risk of data corruption. Refer to [[Automet® FAB - Fit Preference Slider Analysis|fit preference slider analysis]] for further details.

=== Individual bolt hole observations ===
File:AF1.png
The lower table lists recorded bolt hole observations for the selected flange:
</gallery>
* '''Pitch and radius errors:''' Displays angular pitch error (degrees) and radial distance variance relative to nominal pitch circle diameter (PCD) dimensions.
* '''Excluding bad observations:''' Unchecking the '''Fit''' box for an individual bolt hole removes an outlier measurement from PCD calculations without deleting raw survey data.
* '''Pipe end radius:''' When evaluating open pipe ends, radial errors represent individual diameter observations.


=== Touchpoint at OD ===
By default, face gap calculations display clearance at the flange raised face. Selecting '''Touchpoint at OD''' projects gap dimensions to the outer diameter of the flange.


First, we zero flange one by selecting the zero-option box at flange one. Press the apply selections button to see the change in the visual report.
=== Vector and touchpoint display scale ===
The visual scale of vector error arrows and touchpoint leader lines can be resized independently for each flange or pipe end to clean up visual report graphics.


The zero option does not change the report's orientation - the coordinates are translated; shifted along the grid lines, to match the design co-ordinates at flange one.
== Fit and Show Control Options ==


You can now see that flange one has zero vector errors.
The primary controls panel manages component inclusion across the best-fit algorithm and graphical display layers:


<gallery mode = "packed" heights =400 px>
* '''Fit checkbox:''' Controls whether a flange, hub, or pipe end is included in the mathematical best-fit alignment. Unchecking an item excludes it from alignment calculations while retaining its measured variance values in report tables.
File:AF2.png
* '''Show checkbox:''' Toggles the visibility of specific elements (such as circle-fit centerlines) on visual reports.

This pipe-spool report contains some gross errors. You can see this at the touch points on both flanges - there are also large vector errors at flange two.

== Zeroing a Flange to Isolate Gross Errors ==
File:AF5.png
</gallery>


=Dropping a Flange From the Fit=
By default, automet® FAB uses a least-squares averaging algorithm that distributes measurement variance across all flanges. While optimal for compliant spools, this averaging method can mask localized fabrication errors.
For this example, the zero option at flange one has been unchecked, as it will have no effect on the outcome of the next action. We uncheck the fit at flange two.


We call this 'dropping a flange from the fit'.
Selecting the '''Zero''' checkbox on a specific flange anchors the coordinate origin directly to that component, transferring all relative variance onto remaining spools.

Dropping a flange from the fit has a significant impact and the report now looks very different. Only flange one's surveyed data points have been fitted to the design.

Because there are only two flanges, flange one can be zero in all aspects, including position, orientation, and alignment. Even though flange two was not included in the fit, its position, orientation, and alignment are still displayed.
Selecting '''Zero''' at Flange 01 translates coordinates along grid lines to align design and survey origins precisely at Flange 01:


Here is a pipe spool with more than two flanges.

=Fit Preference=
<div style="flex:1 1 320px; text-align:center;">
For a tack-weld survey, the user may wish to change the priority to flange centre-line alignment at the expense of position. With this option, the spool is orientated so that the flange faces are aligned, as opposed to flanges in the best position. The control is a slider, so varying degrees of alignment versus position can be selected.

</div>


Fit: The fit check box excludes flanges and circle fit centres from the analysis.
</div>


=Ignore Length=
Translating the origin reveals gross fabrication errors located elsewhere on the spool, such as excessive vector displacement or face gaps at secondary flanges:
Ignore length: When a pipe spool has pipe ends (i.e. open ends of pipe with no flanges), the default is to ignore the length. The length error is not considered and does not affect the best fit. This option allows for pipe over length. If this is not the case, then the pipe over-length would corrupt the report, so by default, pipe lengths are ignored. The surveyor can change default conditions at any time. The application has a reset-to-defaults button to quickly return to the default condition.


=Align to the Grid=
<div style="text-align:center; margin:16px auto 24px auto;">

=Rotate=
== Dropping a Flange From the Fit ==
You can rotate the spool around its components in the X, Y and Z axes to see how the survey results might look better over the design requirements: [https://youtu.be/csy13yclGL0| Rotate your survey results]


=Translate=
Unchecking the '''Fit''' checkbox for a specific component removes its data points from the mathematical fit.
You can also translate (nudge) the whole spool in 6 axis directions (east/west, north/south, up/down) to see how the survey results might look better over the design requirements: [https://www.youtube.com/watch?v=jhPrYXEIBpk| Translate your survey results]


==Analysis Tools==
When surveying a two-flange spool, dropping Flange 02 forces the alignment model entirely onto Flange 01. Flange 01 displays zero position, orientation, and face error, while Flange 02 displays the true unadjusted error relative to Flange 01.
Vector error graphical analysis is used to access and manipulate survey data; it also displays survey information such as flange thicknesses and the types of devices used.


* The '''fit''' check box allows you to include spool elements in the fit. Unchecking this box removes that item from the mathematical best-fit analysis, but does not remove the values from the report.
On multi-flange spools (three or more connections), dropping a single flange fits the remaining components via least-squares averaging, isolating specific branch fabrication errors (such as an incorrect pipe leg length):
* The '''zero''' check box forces the flange to zero the error at this element. The default is no flange zeroed and all flanges show the best fit. 
* '''Show''' for circle fits reveals or hides the circle fit values on the report.

Analysis Visual Report Information and Controls
Managing context parameters, best-fit calculations, zero translation, transform tools, and visual controls in automet® FAB.

Flange Context Details and Configuration Controls

The sidebar menu displays detailed context metrics and adjustment settings for each component selected in the visual report.

Flange context details and configuration panel

Bolted up

automet® FAB automatically assigns the Bolted up condition when the calculated distance between the diameter-point plane (D) and the stop point (S) matches a two-flange joint thickness. Operators can manually uncheck this setting if a single heavy flange is misidentified.

Diameter, stop, and workpoint indicators

  • D (Diameter plane) and S (Stop point): Circled interface markers indicating physical point locations recorded during field capture.
  • Tie-in and design spool: Refers to the nominal pipe spool design loaded at project start.
  • Gap and thickness overrides: Field-measured flange thicknesses and gasket gap values can be typed directly into the input fields, overriding default database values.

Ignore length

Enabling Ignore length removes the axial length vector from best-fit mathematical constraints:

  • Open pipe ends: By default, open pipe ends are set to ignore length, allowing for excess material without distorting overall spool alignment.
  • Custom configuration: Any flange can be configured to ignore length, or open pipe ends configured to enforce length, depending on site requirements.

Fit preference

The Fit preference slider controls the mathematical weighting applied during best-fit routines:

  • Position: Prioritises reducing vector location errors (black arrows).
  • Alignment: Prioritises reducing flange face angular touchpoint errors (gold values).
  • Reset to defaults: Pressing Reset to defaults restores original parameters without risk of data corruption. Refer to fit preference slider analysis for further details.

Individual bolt hole observations

The lower table lists recorded bolt hole observations for the selected flange:

  • Pitch and radius errors: Displays angular pitch error (degrees) and radial distance variance relative to nominal pitch circle diameter (PCD) dimensions.
  • Excluding bad observations: Unchecking the Fit box for an individual bolt hole removes an outlier measurement from PCD calculations without deleting raw survey data.
  • Pipe end radius: When evaluating open pipe ends, radial errors represent individual diameter observations.

Touchpoint at OD

By default, face gap calculations display clearance at the flange raised face. Selecting Touchpoint at OD projects gap dimensions to the outer diameter of the flange.

Vector and touchpoint display scale

The visual scale of vector error arrows and touchpoint leader lines can be resized independently for each flange or pipe end to clean up visual report graphics.

Fit and Show Control Options

The primary controls panel manages component inclusion across the best-fit algorithm and graphical display layers:

  • Fit checkbox: Controls whether a flange, hub, or pipe end is included in the mathematical best-fit alignment. Unchecking an item excludes it from alignment calculations while retaining its measured variance values in report tables.
  • Show checkbox: Toggles the visibility of specific elements (such as circle-fit centerlines) on visual reports.

Zeroing a Flange to Isolate Gross Errors

By default, automet® FAB uses a least-squares averaging algorithm that distributes measurement variance across all flanges. While optimal for compliant spools, this averaging method can mask localized fabrication errors.

Selecting the Zero checkbox on a specific flange anchors the coordinate origin directly to that component, transferring all relative variance onto remaining spools.

Default least-squares fit averaging error across all components

Selecting Zero at Flange 01 translates coordinates along grid lines to align design and survey origins precisely at Flange 01:

Report translated to zero vector error at Flange 01

Translating the origin reveals gross fabrication errors located elsewhere on the spool, such as excessive vector displacement or face gaps at secondary flanges:

Dropping a Flange From the Fit

Unchecking the Fit checkbox for a specific component removes its data points from the mathematical fit.

When surveying a two-flange spool, dropping Flange 02 forces the alignment model entirely onto Flange 01. Flange 01 displays zero position, orientation, and face error, while Flange 02 displays the true unadjusted error relative to Flange 01.

On multi-flange spools (three or more connections), dropping a single flange fits the remaining components via least-squares averaging, isolating specific branch fabrication errors (such as an incorrect pipe leg length):

Manual Spool Alignment Tools (Transform)

Operators can manually rotate, translate, or align survey data relative to design coordinates using the Transform toolset:

Aligning to grid axes

Aligns designated workpoints or circle-fit centerlines along primary coordinate axes (X, Y, Z).
