Spatial Manager creates buffer polygons around points to show the area within a chosen distance of each location. This is useful for showing a facility’s service area or finding objects near survey points. You can use the same distance for every point or take a different value for each point from its data table. You can also merge overlapping buffers into a single area.

Available for AutoCAD, BricsCAD, ZWCAD and GstarCAD.


In the example video, a buffer of 500 meters is created around the medical centers. A spatial query is then used to find the buildings within that range.

1. Run SPMBUFFER

  • Run SPMBUFFER or choose Tools > Analysis > Buffer.

2. Select points and options

  • Select the source points manually, by query or layer.
  • Enter a fixed width, or choose a data field to provide a value for each point.
  • Set the target layer and choose whether to merge overlapping buffer polygons.

3. Buffer analysis

  • Use the resulting buffer polygons for analysis.
  • Run SPMSPATIALQUERY to select objects that intersect the buffers. You can then highlight them, place them on a new layer, or export them to a new dataset.
