The xamMap™ control can be used to render more than just geographic maps. Some examples of non-geographic renderings include: Flow charts, floor plans, seating charts, wiring diagrams, office layouts, and organizational charts. All that is needed is a GIS shapefile which describes how the rendering should look.
Creating custom shapefiles from CAD vector graphics files
Create the rendering using a CAD tool (Microsoft® Visio®, AutoDesk® AutoCAD®, etc.)
Save the vector graphics tool output to CAD format (.DXF or .DWG)
Convert the .DFX or .DWG file to the shapefile format (.SHP) using a conversion tool.
