<sections>

This part contains properties of cross-section. It is an optional part of XML file. Every cross-section is marked by the element <section>. This element supports following attributes:

id

  • Unique ID, obligatory

type

  • The cross-section type, obligatory. Available values are listed in the table below.

name

  • The cross-section name. Obligatory for hot-rolled cross-sections (the name corresponds to the name in the database).

material

  • The material ID, obligatory

The range of available attributes differ cross-section to cross-section.

Steel

Hot-rolled cross-sections are defined using the attribute "type" (group of cross-sections) and "name" (the cross-section within the group). Available values for the attribute "type":

The attribute "name" corresponds to the cross-section name in the database. This value can be copied from the window "Cross-section catalogue" using the shortcut "Ctrl" + "C".

The cross-section name for the attribute <name>

This attribute has to be identical to the name in the database.
