The purpose of this tool is to allow you to change reference levels without changing the element’s location/elevation.

The tool is going to do it automatically. It will set the correct offsets for you.

No longer, you will have to calculate them manually. Choose the new level (or use another provided option) and it will be done.

Each of the buttons has 6 different options you might use. The levels will be calculated separately for all selected elements.

1. Default

• You will be prompted to choose one level and the tool will try to set it for all selected elements.

2. Set the level to the Closest

• The tool will automatically choose the closest level (the one resulting in the smallest offset) for each element.
• The levels will be calculated separately for all selected elements.

3. Set the level to the Closest Above

• Similarly, The tool will automatically choose the closest level for your elements, but this time it will look only for a level whose elevation is above the selected elements.

4. Set the level to the Closest Below

• Similarly, The tool will automatically choose the closest level for your elements, but this time it will look only for a level whose elevation is below the selected elements.

5. Set the level to the one above the currently selected

• The tool will automatically change the reference level to the one above currently selected. The levels will be calculated separately for all selected elements.

6. Set the level to the one below the currently selected

• The tool will automatically change the reference level to the one above currently selected.

Note: Who should use this tool?

This tool was created with Autodesk® Revit® Modellers in mind. It easily saves them countless hours each year.
I came out with the idea of this tool when I had to change manually references of almost all elements in the projects. This tiny tool would save us at least 2 weeks of work.
