Understanding Layers in Autodesk MapGuide
When working with DWG data especially, it is important to understand the
difference between Autodesk DWG layers, Autodesk MapGuide map layers,
and Autodesk DWG map layers. These are not the same and are defined as
follows:
Changing Map Layer Data Source Properties
When using Autodesk MapGuide Viewer API methods that set Autodesk
MapGuide map layer data source properties, including those for Autodesk
DWG data, keep in mind that the changes you make can affect the validity
of other data source properties for that layer. For example, if you changed the
DWG data source using the
MGDwgDataSources.setDataSource
method
(or the
MGDwgDataSources.DataSource
property), this change could
make existing values for other properties (such as the Autodesk DWG file)
invalid since they might not exist in the new data source.
Layer Type
Definition
Autodesk DWG layer
A single layer within an Autodesk drawing file
(Autodesk DWG).
Autodesk MapGuide map layer
A single map layer defined within an Autodesk
MapGuide map window file (MWF). There can
be several types of Autodesk MapGuide map
layers, including ones sourced from SDF, SHP,
DWG, and so on.
Autodesk DWG map layer
A single Autodesk MapGuide map layer that is
sourced from an Autodesk DWG or Autodesk
Map project drawing.
