I'm trying to determine what the equivalent GeoPak tool/file is to InRoads DTM. I know a DTM is a digital terrain model, however, it looks like in InRoads it is more than just an xzy file, or break line file? (I'm not familiar with InRoads) Is it equivalent to a GeoPak Site file, or just an ordinary tin file? I've heard the InRoads DTM has some intelligence to the elements?
Please explain. Thanks in advance.

An InRoads DTM is comprised of features which are a group of points with a name, style and point type. The name is the unique identifier for the surface feature. The style controls where the feature can display (Plan, Profile, Cross Section) and is also linked to a named symbology which controls the element attributes when displayed in MicroStation-styles and symbologies are stored in the .xin. The feature points are connected with triangles to form a complete DTM. Every feature also has a point type ie. Breakline, Interior, Exterior, Random. When a Surface is created from a corridor in the Roadway Designer, then the proposed DTM will also contain components, which can be displayed as shapes in cross section from which volumes are computed and/or displayed as 3D elements in plan view (i.e. curbing, sidewalks and pavement)
