Anadelta Software is a Greek software development company with many years of experience in the road design software market. It was established in 1993 in the city of Xanthi, Greece, and currently maintains offices in Athens, Xanthi and Lamia.
Anadelta Software's CAD platforms have been used in thousands of road infrastructure projects for almost two decades and have been established among Greek civil engineers as the ideal solutions for road design and construction.
Almost all Greek national roads, such as the Egnatia Motorway, the National Athens-Salonika Motorway or the Athens-Corinth-Patras Highway, have been constructed either in part or in their entirety with the help of Anadelta Tessera, Anadelta Software's flagship highway design software.
Anadelta Tessera is a multifunctional, highly configurable highway design and construction program. It offers a wide range of sophisticated features and capabilities, such as:
Tessera includes an advanced terrain triangulation and processing subsystem. Able to operate quickly and efficiently on models consisting of hundreds of thousands of points, it supports features such as breaklines, nested calculation boundaries, multiple TINs per project, exhaustive terrain consistency and validity analysis and repair, terrain layers, re-triangulation of selected areas only, volumetric operations, as well as extensive post-processing and visualisation capabilities.
The initial road layout can be easily defined, either visually or by importing it from a text file. The software features a complete set of transition curves, such as clothoids, circles and parabolas, which can be freely combined to produce the actual corridor shape. The roadway surface is constantly recalculated and visible during the design stage, along with all information regarding bend geometry (such as radii, bisectors, circle centers, as well as starting and ending points for all curves).
In case of overlapping curves or invalid parameters, Tessera alters the shading on the problematic areas in order to alert the user. Service roads, auxiliary axes, traffic islands, widenings and user-defined corridor sidelines are readily supported. Multiple roads can be defined this way and combined to quickly and effortlessly form complicated intersections and interchanges.
The road profile can be easily modified by using the mouse, while the program displays helpful information such as slopes and height differences, co-depended road elevations and slopes at key points (very helpful for interchange design), as well as any specific geometric properties of the road at the current working position.
By taking advantage of the rich library of typical cross section templates included in the program, the user can quickly and accurately model the required road geometry. Even if an exact match is not found in the library, an existing typical cross section can be modified or a new one can be visually constructed from scratch. In either case, the new cross section can be added back to the library.
As with all other Tessera entities, cross sections are not just drawings, but live objects: editing a cross section, for example, will cause the program to recalculate all affected quantities.
Beyond merely displaying a rendering of the finished project, the built-in 3D environment is an invaluable tool for both inspecting as well as modifying the project throughout its production. It is from within this environment that the user can create 3D video files suitable for presentations, as well as export high resolution images of selected cross sections.
