When a layout type is used on multiple levels, any assignment (such as member size or end fixity) made to a particular member while in Plan mode affects every occurrence of that member. For example, suppose the "Typical" layout type has been assigned to three levels, and beam number 1 is a lateral frame beam in that layout type. Any assignment made to beam number 1 is assigned to all three occurrences of beam number 1 (one at each level). However, in Elevation mode, more flexibility is afforded. Assignments can be made to an individual member, irrespective of layout types. In the preceding example, if an assignment was made to beam number 1 at a particular level but not to beam number 1 at the other two levels, only the beam at the particular level would be given that assignment.

Assignments that were made in Plan mode can be overridden in Elevation mode.
