If you find yourself always deleting the handrails Revit adds automatically to the stairs you create, you should turn off the automatic railing setting.
To do this, click the stair button on the ribbon. But before doing anything else, click the railing button on the Modify | Create Stair tab. Choose “None” from the drop-down and Revit will stop adding those pesky railings.
You can also use this setting to select a different railing type if you don’t like the default.
If this change makes your life easier, open up your template file and make the change there too – now every project you create will work the way you want!
