Summary

The GT_FINDZRNG command in GeoTools allows users to select all objects whose Z-values (elevations) fall within a defined range. This tool is essential for surveyors, GIS professionals, and CAD drafters working in BricsCAD, AutoCAD, ZWCAD and ARES Commander.

GeoTool -> Selection Tools -> Selection Tools -> Find objects in selected Z range

Key Features Include:

• Elevation-Based Object Selection:
  • Filters and selects objects within a user-specified Z-range.
  • Helps in identifying elevation-specific entities in CAD drawings.
• Customizable Z-Range Input:
  • Users can set lower and upper Z bounds to refine selection.
  • Default values cover a wide range (-9999 to 9999), allowing flexibility.
• Practical Applications:
  • QA/QC for Elevation Data – Ensures that objects have correct Z-values.
  • Contour & Terrain Analysis – Isolates features at specific elevation bands.
  • 3D Model Cleanup – Detects objects with incorrect or unwanted Z-values.

Benefits:

This tool is particularly useful for validating elevation data and ensuring accuracy in 3D CAD models.
