The 3D manhole extruder tool allows Bentley Map users to display 3D manholes based on 3D points having proper property information allowing defining the manhole dimensions.
This tool is offered as an example of what can be done with the Bentley Map API and comes without any guarantee or support.
The source code for this tool and others is available in the "Bentley Map - Development and Product Customization Guide" on the "Bentley Geospatial Desktop Extranet".
