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

Dissolve

The command ‘SPMDISSOLVE’ in Spatial Manager™ for BricsCAD allows you to generate new polygons based on the grouping of other adjacent polygons with some common data.

• Dissolve options: You can select the common table/field data for dissolving the polygons (even including null data).
• Label options: Define the style, height, and justification of the label text entities.
• Table/Layer name: Defines the target Layer and data table name for the new dissolved polygons.
  • Use field values for Layer.
  • Apply random colors to new Layers.
• Create: Dissolved entities type, borders, or polygons. The polygons option allows you to select MPolygons as the type of entity to use (BricsCAD 20 and upper). The MPolygons can be defined by multiple rings, even including holes, as a single BricsCAD entity.
  • Fill areas using Hatches.
• Treat closed polylines as polygons: When checked (default value), all closed polylines will be considered polygons.

Note: Since this operation can only be performed on polygonal entities, the application will alert the user either if there are non-polygonal entities attached to the selected table (warning) or if there are not enough polygons to process it (cancellation).
