ROHR2 Interfaces to CAD systems

Neutral CAD Interface ROHR2

The data for generating a pipe model in ROHR2 is done by importing files from 3D Plant engineering systems by integrated interfaces (some of them optionally available).

The ROHR2 Neutral Interface is the main program module for the integration of CAD-programs and  part of the current ROHR2 standard package or available as an upgrade.

The ROHR2 neutral interface is required part of the process and included in the current standard program configuration ROHR2 static & dynamic.

These CAD-Systems are creating data in the format of the Neutral interface enabling the direct data import into  ROHR2:

  • RC-Planet (Planet GmbH),
  • MPDS4 (CAD Schroer),
  • HICAD (ISD GmbH), u.a.

On the part of the CAD/CAE system optional modules may be required for the generation of an export file in Neutral file format

ROHR2 CAD interface package

ROHR2 CAD interfaces are available in an optional CAD package whcih contains the modules

  • PCF - ROHR2
    for the import of data from Autocad PLANT3D, Intergraph SMARTPLANT, SolidWorks Smap3D, SolidWorks Solidplant, Venturis TRICAD, CADMATIC, ESAin ESApro etc
  • Intergraph PDS - ROHR2
  • SDNF – ROHR2 (structural steel)

The import data is basing on integrated component databases or database reports instead of simple graphic data. This enables to get more information than a simple piping structure, like assignment of materials, dimensions or support positions, required for the modeling in the ROHR2 pipe stress calculation.

PCF format data fransfer

The PCF format is used by several CAD-systems to create isometrics like AUTODESK AUTOCAD Plant3D, Intergraph SMARTPLANT or Pro/ENGINEER.
The PCF interface is used to convert data from various CAD systems into ROHR2 and to export ROHR2 system data in *.pcf format
The interfaces can be adapted individually to the imported data by a configuration dialog.

Interfaces for the conversion of piping structures

The creation of a piping model by means of graphics data information (e. g. AUTOCAD *.dwg) allows to generate a geometry model in best case. ROHR2 does not support this working method, because modeling in ROHR2win is the more efficient way to get a piping model.

3D DXF data import
Generate a ROHR2 model from 3D isometrics in DXF format (*.dxf)
All types of lines („LINE“, "POYLINE“, „LWPOLYLINE“) are used to generate ROHR2 segments.
Select the layers which need to be considered.

CSV import interface – Reading geometry data from text files
The interface CSV is used to convert data in text format (*.csv - comma separated value) into a format readable by ROHR2.

This way piping structures can be generated to get a ROHR2 project piping model. Parameters, relevant for the calculation need to be added in the ROHR2 project.
