Structural Physical Model Selection

Physical to Analytical for Buildings 2025.2 automates the analytical model for most of the structural elements.

Some elements, even if created as Revit structural objects, do not need to be represented in the analytical model (e.g. parapets, partition walls, etc).

As the automation tool analyzes all the structural elements in your selection, it is very important to isolate the ones for which you want to create the analytical representation.

Physical elements for which the analytical model creation process can be automated

• Structural Columns: Vertical and Slanted Columns.
• Structural Framings: Straight line beams and Arc curved beams.
• Floors
• Foundation Slabs
• Walls: Straight line walls.
  
  
  

Note: Spline beam and curved wall creation cannot be automated. These can only be created manually, preferably after the automation generates the analytical representation for the other structural elements.

Physical elements and their associated analytical representation

The automation creates one associated analytical representation for each structural physical element in the form of analytical members for linear elements, or analytical panels for planar elements.

Note: For floors with multiple closed contours, the automation process will create an associated analytical model for each closed contour.

The default position of the created analytical element is:

• By the geometrical axis of linear elements.
• By the middle of the structural wall.
• On top of the floor/foundation slab.

The analytical model will be aligned and adjusted later, based on the specific alignment and connectivity rules.

The properties inherited by the analytical member from its physical counterpart are:

• Material
• Structural Role
• Cross-section: in the form of Family and Type.
• Cross-section rotation.

The properties inherited by the analytical panel from its physical counterpart are:

• Material
• Structural Role
• Structural Layer Thickness

Analytical representation simplification

The Physical to Analytical for Building 2025.2 evaluates some physical model particularities when creating the analytical representation:

• The cut-outs made by the structural join in physical elements are ignored:
  

• The analytical panels for physical floors and foundation slabs are created based on the precise contour of the corresponding physical element.
