As of now any section defined in Free Sketch or Section builder and exported to STAAD.Pro as a general or a prismatic section, comes in with the properties only.
The .upt file created as a result of the export, does not contain information related to the actual shape of the section.
Hence in STAAD.Pro, the section is shown as a line.
