Spatial analysis in GstarCAD

Perform spatial analysis operations in GstarCAD over the objects in the drawing generating new objects from such analysis

Spatial Manager™ for GstarCAD provides a comprehensive set of tools to perform spatial analysis operations with the vector entities in the drawing and their attached data, resulting in new objects generated by the resolution of such operations

Spatial analysis operations can be performed on a combination of tables, layers or drawing objects previously selected by interacting with on-screen elements or by using the application's advanced selection queries

Buffer

Generate Buffered polygons around point, linear or polygonal objects

Overlay<span style='font-size: 1rem;'> - <a href='overlay/' class='app_color_link'><span>More info</span><i class='icon-chevron-right ml-1'></i></a></span>

Overlay

Allows you to create new objects based on geometric and data operations between two existing object groups. These operations are':' Intersect, Union, Erase, Identity, Clip, Paste and Symmetric Difference

Dissolve<span style='font-size: 1rem;'> - <a href='dissolve/' class='app_color_link'><span>More info</span><i class='icon-chevron-right ml-1'></i></a></span>

Dissolve

Generate new Polygons based on the grouping of other adjacent polygons with some common data

Polygon centroids<span style='font-size: 1rem;'> - <a href='polygon-centroids/' class='app_color_link'><span>More info</span><i class='icon-chevron-right ml-1'></i></a></span>

Polygon centroids

Allows you to generate polygon Centroids (Point objects) by adopting the polygons data, or add Centroids data to the polygons that contain them

Areas of Influence

Creates polygons defined by the sets of points closest to each point of a selection in the drawing (Voronoi diagrams)
