Moving Load Envelope

[omh1980]

Hi all, I am looking at these moving load analysis envelopes but my question is which load permutation(1 lane loaded or two or more lane loaded with multiple presence factor) position of trucks is giving you this ultimate section forces. Is there any way to extract this info from the software or should i do it manually by using the influence lines (which is pretty hard work to see the governing load case)
thanks alot
