I am not able to run the application, as it is disabled. Why?

OneRay-ST button disabled

When you run Autodesk Revit, the OneRay-ST application button could be disabled (Fig 1).

To enable the OneRay-ST application button you need just to load the Revit family included in the OneRay-ST application. You will find the Revit family into the application download package file.

This is the workflow:

  1. Launch Revit and open your project;
  2. Load the Revit family;
  3. Double click on the Revit family. Now it’s possible to click on the OneRay-ST button to start drawning your customizable Spiral Stairs.
