Data Exchange

We want to make sure that you always benefit from the best possible data exchange interface, which is why you – as a ProVI user – don’t have to acquire all the interfaces individually because they are already included in all our software products.


Standardized Interfaces

ProVI plays an active role in the enhancement and refinement of standardized interfaces such as IFC and OKSTRA to ensure that data can be shared even more quickly and smoothly among different software systems in the future. Our software already supports the following formats:


Long established in the building construction industry, Industry Foundation Classes is increasingly becoming the standard data exchange format for BIM applications in the civil engineering sector too, because it can be used for importing and exporting not only alignments and vertical alignments but also 3D bodies with attributes.


This is another popular BIM interface and also supports CPIXML export, which can be used for exporting attributed area and volume models to tender programs such as iTWO or 4D/5D design software.


You can use the CityGML interface to import 3D models of the existing urban landscape to your ProVI project so that you can visualize your designs in their actual context.


You can use the KML interface to export all the georeferenced 2D and 3D elements in your CAD drawing directly to Google Earth, where they can be shown in context. This is the perfect visualization tool for meetings and hearings.


This international standard format allows you to use our software to import and export alignments, vertical alignments, longitudinal profiles, cross-sections, terrain models and point data.


ProVI can transfer ALKIS (Authoritative Real Estate Cadaster Information System) data in NAS format directly to a cadaster drawing or import this data for determining land acquisition. Since the objects are usually assigned UTM coordinates, these can also be transformed to the Gauss–Krüger or DBREF system.


The ISYBAU interface allows the loss-free exchange of drainage network data among ProVI and other systems, which means that you can perform hydraulic calculations in almost any hydraulic software program.


OKSTRA (object catalog for road and traffic networks) from BASt allows you to export topological and parametric design data for road routes and land acquisition to other systems. This makes it the primary interface of choice whenever this data needs to be processed further in another system.


IDMVU (infrastructure data management for transportation companies) provides a standardized traffic infrastructure object catalog for transportation companies. ProVI allows you to import and export alignments including station jumps, cants, vertical alignments, switches and structures.


The Regulations for Electronic Construction Billing (REB) define numerous widely used data types (DA) also supported by ProVI:
DA001 and DA45 (point data), DA49 (breaklines), DA58 (terrain models), DA40 and DA50 (alignments), DA21 (vertical alignments) as well as DA54, DA55 and DA66 (cross-sections)

Interfaces with Track Network Databases

With ProVI, you can share route designs with the track network databases of various national railway companies:



This allows you to share design data with DB-GIS (the GIS system widely used by DB AG) via the GND-Edit test program. All the data required for this is generated by ProVI and can be imported with GND-Edit.


The IGleis interface allows you to share data with the ÖBB track network database. The interface allows you to import and export not only alignments and vertical alignments but also the cant development and any point data (masts, fixed points and switch points).


TopoRail is a route design program used by Swiss Federal Railways (SBB). The interface allows you to share alignments, vertical alignments, cants and points.


This interface allows you to share alignments with cant and speed bands and vertical alignments with Dutch railway organization ProRail.

Interfaces with Other Design Systems

ProVI can also read and write numerous different file formats from third-party systems so that the following data can be shared:

  • Civil3D: Sharing alignments, vertical alignments, longitudinal profiles and terrain models
  • Revit: Exporting platforms from the route model to Revit
  • VERM.ESN: Sharing alignments, vertical alignments, cants, reference points and plane frame coordinates
  • OLAcad: Importing catenary masts  from OLAcad to the ProVI model
  • SicatMaster: Exporting alignments, cants and vertical alignments (GLT)
  • Fides Infrastructure Toolbox: Exporting space curves as reference lines for designing civil engineering structures
  • ProSig: Sharing alignments, cants, speeds, vertical alignments and switch positions
  • Card_1: Sharing alignments, vertical alignments and line files
  • Vestra: Sharing alignments and vertical alignments (S30, S40, D20, D21)
  • InRail/InRoads: Sharing alignments and vertical alignments
  • Caddy: Importing points and breaklines (GM1/GM2)
  • GeoGraf: Exporting alignments and vertical alignments (GGR)
  • ems-i: Importing terrain models from environmental modeling systems (TIN)
  • Earthworks Quantities Calculation Program: Exporting cross-sections (EWXP)
  • Filmbox: Exporting project data for visualization in VR viewers (FBX)

Device Interfaces

ProVI can read point data directly from surveying equipment from different manufacturers and, at the other end, output control files for automatic construction. Importing column-formatted point data is also child’s play.

  • Leica: Importing point data in GSI format
  • Zeiss: Importing point data in M5, R4, R5 and Rec500 format
  • Sokkia: Importing point data in SDR33 format
  • Plasser & Theurer: Exporting alignment and vertical alignment data and track displacement values for the automatic guiding computer in tamping machines

CAD Interfaces

Since ProVI is based on AutoCAD/BricsCAD, you can automatically import and export CAD drawings in a wide range of different formats. AutoCAD, for example, offers the following drawing formats:

  • DWG
  • DXF
  • 3ds (3D Studio)
  • DGN (MicroStation)
  • PDF
  • IGES
  • STEP
  • Inventor
  • SolidWorks
  • Rhino
