Graphic modeling is used more and more today in the designing of underground structures. This application was developed to input, to store and to view 3D scenes of underground communications.
















3D drawing:

• makes a strong impression from an object
• allows to look at an object from any point and angle
• allows to present precisely shape and dimensions of an object
• allows to easy analyse different solutions on the designing stage

3D visualization of underground communications permits to investigate a project on any stage of designing. This method allows as to build exact model of future object, as to demonstrate a project on any stage of development.

• This system allows to build a virtual three-dimensional model of underground communications that can be viewed from any point
• This system allows to present as underground lines and structures, as a relief of earth surface
• This system has a structured data storage
• This system automates the user work to build 3D models on source spatial data
• This system can operates with many model objects that allows to create exact model of underground space
• This system allows to create electronic archives of models

Presented solution has some advantages:

• an ability to keep attributive information, i.e. each model object has a series of related attributes describing its physical, economical, and other characteristics as well as image
• internal exchange format (based on XML) which simplifies input, exchange and validation of data
• role-based security system which allows to distributes functions among user groups
• extension modules (plug-ins) which allows to extend the system functionality
