Advanced geometry tools for GstarCAD

New in V10

A suite of geometry tools for GstarCAD designed to edit, transform, and optimize a wide range of vector elements, including polylines, polygons, and other geometries

These tools enable advanced spatial operations such as simplifying shapes, generating polygons from point sets, joining or splitting elements, and converting between geometry types.

Polyline tools

 New in V10

A powerful set of tools for editing and transforming polylines. Whether you need to compound new lines from anothers, convert between 2D and 3D polylines, reduce complexity using simplification, or create new linear geometries from points, these tools will help your workflow

Polygon tools

 New in V10

A set of polygon tools designed to simplify and enhance your spatial editing tasks. Dividing polygons into smaller sections, generating polygons from point sets, merging adjacent polygons, or creating polygons from intersecting lines

Geometry editing tools

 New in V10

A wide range of functions to edit, reshape, and analyze spatial geometries. From aligning datasets using Rubber Sheet, cutting or trimming features with Break and Trim, to generating new geometries such as Convex Hull, Envelope, or Triangulation. Additional capabilities like Simplify reduce complexity in shapes or Vertex extraction are available
