Training Path Module 5
Overview
Selecting Visual Report from the main application menu following a survey compares captured field observations against design specifications (`.DES`).
The visual analysis suite enables surveyors to rotate and translate models, include or exclude specific flanges from least-squares fit calculations, zero individual tie-ins, adjust fit weighting preferences, and isolate gross fabrication errors.

File Dependencies and Opening Surveys
Analyzing survey data requires two corresponding files:
- Survey File (`.SUR`): Contains observed field coordinate data.
- Design File (`.DES`): Contains baseline CAD model geometry.
To analyze a previously completed survey, select Open for Analysis adjacent to **Survey File:** on the main interface—the corresponding design file loads automatically. If a survey was just completed, click Visual Report directly.

Manual Transforms and Model Adjustments
The **Transform** module allows surveyors to manually translate and rotate survey models across six degrees of freedom (X, Y, Z axes).

Open Tie-In Surveys
When analyzing open tie-in site surveys, enable the **Open Tie-In** function to prevent coordinate fit distortions.

Report Generation
automet® FAB generates three specialized documentation reports following analysis setup:
Visual Error Report
3D graphical view displaying vector arrows, rotational offsets, and face touch-point gap dimensions.
Text Report
Tabular coordinate listing showing actual vs. design coordinates, D-point locations, and alignment angles.
QA Integrity Report
Quality audit verifying face planarity, PCD errors, device types, and multi-setup instrument move precision.
Visual Error Graphical Report
All displayed values represent deviations from design; a perfectly manufactured spool yields all **zero values**.
-
Full 3D graphical visual error report
- Vector Errors (Black Arrows): Indicate displacement magnitude and direction (+1.4 mm Z, +0.6 mm Y North, +0.8 mm X East). Correct by adjusting physical flange in the opposite direction (-1.4 mm Z, -0.6 mm South, -0.8 mm West).
- Bolt-Hole Rotation (Blue Curved Arrow): Shows rotational error magnitude (in mm) and direction.
- Touch Point (Gold Value): Identifies the raised-face high point contacting the mating flange first. The value represents the gap opening on the opposite side.
- Open Pipe End Long Point: Identifies the longest point on un-flanged pipe ends to guide field bevel grinding.
