Modifies all types of cross sections.

Inputs

NameIDDescriptionType
CroSecCroSecCross section to modify on the fly or no input if modification shall take place in the model based on the name of the cross section.CrossSection
Type name of cross sectionNameThe Type name serves to identify a cross section uniquely upon selection from a cross section table.String
Family name of cross sectionFamilyFamily name of cross section: defines a group of cross sections for cross section optimization.String
Element identifiersElem-IdsList of identifier of elements to attach cross section to.String
ColorColorColour of the cross section.Colour
