11.3 Section Elements

If you wish to apply superelevations to the template, you should check the different parts of the section, in order that the application knows how to modify the section. You can change the type of each part from the table that defines the template or use the corresponding icon on the toolbar.

Superelevations: Part of the section that is modified on applying the superelevations.

Fixed: Part of the section that is not modified, but is moved to coincide with the parts of sections that are connected.

Variable: Part of the template that is lengthened or shortened to coincide with the fixed part or superelevations from the earlier or subsequent part of section. A template may only have one or two variable parts.
