Summary

The GT_PLANARPOLY command in GeoTools allows users to convert polylines and 3D faces into perfectly planar geometry, ensuring that all vertices align on a single plane. This is essential for photogrammetry, rendering, and 3D modeling applications, where non-planar geometry can cause errors in visualization and data processing.

GeoTool -> Drawing Cleanup Tools -> Drawing Cleanup Tools -> Make polylines/3dfaces planar

Key Features Include:

• Adjusts polylines and 3D faces to ensure all vertices lie on the same plane.
• Works by modifying adjacent vertex elevations within a specified tolerance.
• Works seamlessly in BricsCAD, AutoCAD, ZWCAD and ARES Commander.
• Supports both general polylines and special cases of 4-vertex polylines where planarity can be achieved.
• Ideal for photogrammetry, 3D modeling, terrain data correction, and rendering workflows.
• Helps eliminate geometric inconsistencies, ensuring clean and accurate planar surfaces.

Benefits:

With GT_PLANARPOLY, users can quickly fix non-planar geometry, improving data accuracy and visualization quality in CAD and GIS workflows.
