If you can find a way to get the points into Excel you could use Curve by Table command.
There is a line segment option that will give you a locatable vertex at each point location.
I would like to see the file.
As both IGES and STEP are text files, it would fairly easy to parse the data and extract all point data into a .csv file for use by Excel, which in turn could then be pushed into Solid Edge.
If you could provide your sample file for review.
Thank you and regards,
