Problem:

How to export an AutoPIPE model into an I-model file format?

Solution:

There is no file format that can be directly export from AutoPIPE  to I-model. However there is a workaround:

instructions for AutoPIPE V8i 09.05.xx.xx and higher:

1. With the model opened in AutoPIPE, select File> Export> DGN model (DGN). 

2. When the dialog screen appears, save the file name to a folder location, check all applicable boxes, press OK button to continue

3. With Bentley I-model composer installed on your system, follow the programs instructions to open a DGN file and convert it to a I-model.
