• SteelDesign - Sets which steel design code that will be used in GSA
• ConcreteDesign - Sets which concrete design code that will be used in GSA
• Country - Sets which country specific parameters that should be used with the design codes. Only applicable for some of the codes.

By default the load combinations when pushed to GSA will become Analysis Tasks of the type "Static". To change to any other type, set the CustomData with key "Task Type" to the following:

• "NL_STATIC" - Will give a Non-linear static analysis task
• "FORM_FIND" - Will give a Form finding analysis task ignoring soap film properties [otherwise known as staged analysis]
• "SOAP_FILM" - Will give a Form finding analysis task using soap film properties
• "STATIC" - Will give a static analysis task, which is the default behaviour

Section Properties for bars can make use of modifiers to change the various stiffness's. This can be done via the "ApplyModifiers" method in the Structure_Engine.

If the CustomData key "Dummy" is set for the bars, the a DUMMY tag will be applied to the object.
