Have you ever tried to import your survey points into InfraWorks 360 using a simple CSV tabular format like an Excel spreadsheet?
Admittedly, without knowledge of FDO, GDAL, and OGR, this can seem like a daunting workflow at first. But once you get the hang of it, it's a pretty quick and painless operation. Not to mention-- once you try this out once or twice, your eyes will be opened to the magic of using a variety of different data providers to bring your data into InfraWorks 360.
For this example, I will use publicly available survey points for the Boston Seaport area (sourced from the Massachusetts DOT) that I have copy-pasted into a CSV, and import those survey points into InfraWorks 360 as points of interest, using an OGR:VRT generic data provider connection.
