Prepare to use the Rail surface tool

Set up the options for the Rail surface tool

The Surfaces > Swept Surfaces > Rail Surface tool has options that control how many Generation Curves and Rail Curves it expects.

You can open the tool’s option box and change those options depending on how many curves you have whenever you use the tool.

Or, you can set up multiple custom versions of the tool on a shelf, corresponding to the different combinations of Generation Curves and Rail Curves options. See the section Create custom tools for more information.

TipCustom versions of the Rail surface tool corresponding to the different Generation Curves and Rail Curves settings are included on the default shelves that ship with Alias.
NoteAlias automatically assigns different icons to different custom versions of the Rail surface tool depending on how the Generation Curves and Rail Curves options are set.
