Automatic Detection of Revit Structural Models
When creating structural elements in a project, the automatic detection feature will adjust the analysis model accordingly:
For beams, during their creation, the projection plane from the beam to the structural floor is set to Automatic detection for the vertical projection of the beam’s analytical model. The parameters align as follows:
For columns, the automatic detection function ensures that the analytical models of both the column and the wall are placed on the same plane.
Regarding structural floor slabs and walls, the automatic detection function aligns the vertical and horizontal analysis projection planes of the wall during creation, regardless of any changes in wall thickness or the position of the projection plane.
If a wall connects to a floor, the top or bottom plane of the wall’s analytical model will correspond with the floor’s analysis model.
In cases where a portion of the wall extends above the roof—commonly known as a parapet—the wall’s analytical model can be configured to exclude loads and framing components that extend beyond that elevation. When the analysis edge of the floor slab matches the analysis model of the beam or wall, the exterior of the wall can serve as the analysis projection plane. Additionally, it can be trimmed back to align with the analysis or physical model of the floor slab, as illustrated below:
