Maps and Layers

Detailed Description

A map (AcMapMap object) corresponds to a single AutoCAD Map 3D drawing file (.DWG). To get the map for a drawing file, call AcMapMap.GetCurrentMap().

Note:

The classes AcMapMap and AcMapLayer are derived from the Geospatial Platform API classes MgMapBase and MgLayerBase. Some operations require casting the base classes to the derived classes. See the Geospatial Platform Supplement Reference for information about all AcMap* classes.

AcMapMap map = AcMapMap.GetCurrentMap();
MgLayerCollection layers = map.GetLayers();
foreach (AcMapLayer layer in layers)
{
    // process the layer
}

For additional information about manipulating and rendering maps, see the AutoCAD Map 3D Geospatial Platform Developer's Guide.
