Importing the model from HEXAGON CAESAR II into PASS/START-PROF is not trivial task for programming. PASS/START-PROF has high level modern object-oriented piping model, CAESAR II has low level spreadsheet based piping model, where user can type the information in any form manually. Although currently for most of the cases, nearly 90% of pipe route it is possible to import automatically. Other certain items may require be completed manually in the PASS/START-PROF side after automatic conversion. If you have any issues, please send us the input files and we will improve and send you the new converter module in 1-3 days.

CAESAR II and START-PROF Differences

Verification CAESAR II and START-PROF Model 1


Function allows to import piping model from CAESAR II neutral format files (.cii) v.7, v.8, v.9, v10, v11, v12. See Video 1 and Video 2.

To import the model first export it into neutral format in CAESAR II:

Also load cases may be exported into the Excel file

It is possible to import data as described below:

In this dialog you can specify the Excel (.xlsx) file with the load cases, that should be imported into PASS/START-PROF (CAESAR v.11 and v.12)


The path to configuration files can be found and changed in General Settings

Export from START-PROF into CAESAR II

PASS/START-PROF to CAESAR II converter translate the model geometry and properties from START-PROF to CAESAR II v.11. User can choose the units in which the model will be converted to CAESAR II. At this moment the converter can transfer:

1. Pipes and rigid elements

2. All types of bends except the single miter joint, and long radius bend, because such elements are absent in CAESAR II

3. All types of tees

4. All types of reducers

5. Valve

6. All type of joints

7. Nozzles WRC 297, PD 5500, API 650

8. All types of supports and hangers, including START-PROF custom restraints

9. All types of Expansion Joints including it's properties

10. Cold spring (cold pull)

11. Support movements

12. Pipe Code used for stress analysis

13. Materials

14. Flange leakage check

15. Uniform and node loads
