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..

Overlay

The command ‘SPMOVERLAY’ in Spatial Manager™ for AutoCAD allows you to create new objects based on geometric and data operations between two existing object groups.

This function allows you to generate new objects in the drawing by performing geometric operations between two groups of existing objects: “Source” (Group 1) and “Overlay” (Group 2).

• Objects selection: For Group 1 and Group 2, review the selection control.
• Overlay parameters and options:
  • Operation:
    • Intersect.
    • Union.
    • Erase.
    • Identity.
    • Clip.
    • Paste.
    • Symmetric Difference.
  • General options:
    • Table/Layer name: Defines the target Layer and data table name for the newly created objects.
      • Apply random colors to new Layers.
    • Create: New Overlay objects type, borders, or polygons. The polygons option allows you to select MPolygons as the type of object to use. This option is available on all compatible Autodesk products (even on vanilla, plain, or basic AutoCAD) (AutoCAD 2013 and upper). The MPolygons can be defined by multiple rings, even including holes, as a single AutoCAD object.
      • Fill areas using Hatches.
    • Treat closed polylines as polygons (Both Source and Overlay sets): When checked (default value), all closed polylines in the drawing will be considered polygons and not linear objects.
