This document describes HydrOffice QC Tools 4.9.9.

2.3.4.1. How To Use?

Scan grids for unpopulated nodes (“holidays”).

  • Select the Holiday Finder tab (Fig. 2.19) on the bottom of the QC Tools interface.

  • To change the Parameters for Holiday Finder v5:

    • Click the Unlock button, and click OK to the dialogue.

    • Activating Identify all gaps in the grid will activate a special mode that will return all the holes, regardless of size, in the grid and will override the Feature Detection requirement chosen in the input window.

    • Set the Upper holiday area limit (as multiple of minimum holiday size). Unpopulated parts of the grid larger than this setting will not be flagged as holidays.

  • In Execution, click Holiday Finder.
