PTV Vissim - Frequently Asked Questions (FAQs)

(#VIS25858)

Are models built in earlier releases of PTV Vissim compatible with later releases?

Yes, generally, models built in earlier releases of PTV Vissim can be read in later releases.

Network files created in VISSIM 5.40 or earlier have the extension *.inp, whereas those created in PTV Vissim 6 or later have the extension *.inpx.

*.inp files created in VISSIM 5.30 or earlier must first be saved in VISSIM 5.40-13 before they can be opened in PTV Vissim 6 or later versions.
