Properties
This shows the values of the section properties as used in analysis (i.e. with modification factors applied). Depending on the stiffness calculation option the modifiers will apply to either the yz or uv values.
Convert to Perimeter
At times it may be useful to convert a section from a catalogue section or a standard shape to a perimeter (typically where the section may require some adjustment). When this option is selected the original section can no longer be modified.
Export
The export option allows the section shape to be exported to a DXF file. The section is exported as a series of LWPOLYLINE entities.
More
The 'More' option displays a more comprehensive list of (unmodified) section property values.
