Shared Elevations

The Shared Elevations tool allows you to automatically assign elevation values to elements in your Revit model by populating two shared parameters: ALAB_BIM_SharedBottomElevation and ALAB_BIM_SharedTopElevation.

These parameters represent the lowest (bottom) and highest (top) Z-values of an element’s bounding box in the current view. This is especially useful for QA, coordination, IFC export, or managing facade elements where precise placement and elevation tracking are required.

The tool lets you:

• Select which Revit categories to include (e.g. windows, walls, etc.)

• Populate the elevation parameters for all instances in those categories

• Filter and search categories to focus on relevant elements

• Validate if the necessary parameters are already added to the project

💡 Ensure the two shared parameters are added as project parameters before using the tool.
