Returns

boolean - Returns True if successful; otherwise returns False.

Error Codes

Example

This code is designed to work with the 1stfloorplanEx6.mwf file used by the Filter DWG Layers example:

function setProperties()
{
   // Get the map and selected features
   var map = getMap();
   var mapSel = map.getSelection();
   // Use the single map layer Floor Plan
   var mapLayer = map.getMapLayer("Floor Plan");
   // Get DWG data source object for the layer
   var mapLayerSetup = mapLayer.getLayerSetup();
   var dwgMapLayerDataSource = mapLayerSetup.getDwgDataSources();
   dwgMapLayerDataSource.setKeyColumnType("Integer");
}
