Summary
The GT_BOUNDARY command in GeoTools allows users to generate closed boundary polygons around points while simultaneously placing centroid markers. This tool is essential for GIS, land parcel mapping, and topographic modeling in BricsCAD, AutoCAD, ZWCAD and ARES Commander

Create a Boundary (Closed Polygon) Around a Point: GT_BOUNDARY – GeoTools Command
Key Features Include:
- Boundary Type Selection:
- Polyline: Creates closed polyline boundaries around selected points.
- Region: Generates region objects, useful for GIS topology analysis and spatial calculations.
- Centroid Placement Options:
- Points: Places CAD point objects at the centroid of each created boundary.
- Blocks: Inserts block references at centroid locations for better annotation and feature identification.
- Customizable Block Placement (For Centroid Blocks):
- Allows users to define block names for centroid placement.
- Supports scaling and rotation adjustments for proper alignment.
- Attribute Data Handling:
- Supports area attributes and length/perimeter attributes to store topology details.
- Allows assigning object data fields for integration with GIS or CAD databases.
- Layer Management for Boundaries:
- Users can define a specific layer (default: “POLYGON_BOUNDARY”) where the created boundary polygons will be placed.
Benefits:
- Automates polygon boundary creation, saving time in parcel and land-use mapping.
- Ensures accurate centroid placement for GIS feature identification and labeling.
- Integrates with spatial analysis workflows, enabling better area-based calculations.
- Enhances topographical and urban planning by ensuring clean boundary definitions.
This tool is highly valuable for surveyors, GIS professionals, and CAD users involved in land management, zoning, and infrastructure planning.
