Structural Floor Analysis Properties

Modify the analytical properties of the structural floor to accommodate structural analysis tools and procedures.

To change structural analytical properties, select the element. In the Properties palette, select the element specific analytical properties from the Properties filter.

Note: The following table has been reorganized to reflect the Properties palette available to students and to Autodesk Maintenance and Desktop Subscription customers of the Revit 2015 R2 release of the software.
Name Description
Analytical Model
Analyze As Either One-Way or Two-Way. Specifies the transfer of a load through the floor to its supports.
Analytical Properties
Family Type The family type of the element.
Physical Material Asset The name of a physical asset assigned to the floor material (read-only).
Area The total area of the structural floor.
Perimeter The total perimeter of the structural floor.
Analytical Alignment
Alignment Method

Either Auto-Detect or Projection. Specifies if the horizontal and vertical references of the structural floor are automatically justified or have a defined projection.

z Projection Either Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when Alignment Method is specified as Projection.

If in sketch mode, this parameter will default to Floor/Slab edge for either the whole model sketch or just a sketch line.

Specifies the vertical location of the analytical model at the base of the structural floor.

Identity Data
Surface Number An identifier created for the analytical surface. This value should be unique across Analytical Floors, Analytical Foundation Slabs and Analytical Walls in a project. Revit warns you if the number is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.
Comments User comments.
Phase Created Indicates in which phase the floor was created. See Project Phasing
Phase Demolished Indicates in which phase the floor was demolished. See Project Phasing
