# Add catalogue sections
This allows selection of a group of sections from a catalogue which are added to the section library.
Definition
Member type & material
Depending on the context the member type can be preset and a material grade is then chosen for the section. An analysis material can be assigned or the option to derive properties from the grade can be selected.
Catalogue & type
A catalogue and type are selected and then the corresponding sections are listed and can be selected.
Name
Normally each section should be assigned a unique name, so the name specified is a template that can be expanded for the individual sections.
<g> – material grade
<t> – member type
<d> – section description
<s> - section number
So for example for a steel section with a grade S450 and a profile UB457x191x89 and a name 'Steel <g> <d>' would result in a name Steel S450 CAT UB UB457x191x89'.
Steel design attributes
Details for steel design, such as net : gross area ratio can be specified.
