4. How can I get data transferred between STAAD.Pro and Autopipe ?

The transfer of data between Autopipe and STAAD is done through Pipelink. You should ensure that you have the latest available versions of both STAAD.Pro and Autopipe software. The data transfer process is explained in detail in the document PIPELINK_tutorial.pdf

6. Why my DXF drawing is not imported correctly from AutoCAD into STAAD.Pro?

There are basically 3 rules to adhere to when generating these DXF files from AutoCAD:

1. All entities must be modeled in your AutoCAD model using simple Lines. STAAD does not import polylines or curves of any forms. You must "explode" the polylines or curves and convert them into simple line entities in AutoCAD before you create the DXF file.
2. Plate elements if any, must be modeled using 3DFace entities in AutoCAD.
3. Since solid element data cannot be stored in DXF files, STAAD cannot import solid element data.
