Step 1. Build the object you want to make into a prefab. Here I have staircase I want to make into a reusable object.
Step 2. Drag all the objects onto one, to make it a parent of the others. Prefabs need one top-level entity.
Step 3. Click on the top-most object in the hierarchy and select the "Save as Prefab" menu item. You'll get a file save dialog so you can choose the file to save.
Step 4. Begin using your prefab by dragging it into the scene from the asset browser.
Prefabs will always be reloaded from the original prefab file. Even if you overwrite the prefab file, your changes will be instantly reflected throughout the entire scene. If you make any changes to an object loaded from a prefab that would make that object so it is no longer instanced, a dialog box will warn you and ask if you want to proceed before turning it into a unique object.
Prefabs can be made from all entities in the editor, not just CSG brushes.
