Is this impossible? I keep getting "Can't end Stairs with Riser because Riser Thickness is too small."

I have the stair now, but the error message still will not clear. Any suggestions?

Ignore the error, your stair is fine. The stair tool is a little crazy :)

Monolithic stairs must end with a tread, because the treads and risers are both part of the same monolithic element. which means there is no actual tread or riser thickness. If you end with a riser at the top, the riser has to have some thickness, but that field is grayed out on monolithic stairs.

For exterior stairs coming up to a door with a landing at the top, I just make my top tread be the whole landing. Works great and looks correct in elevations and sections.

For interior monolithic stairs, I usually use linework to get rid of the lines around the top-most tread (which is at the floor level and indeed is part of the floor).

Of course being able to join stairs to floors would alleviate all these issues.

How would you go about making the top landing (which is actually the top stair tread) to be wider than the tread widths? Imagine a 4'-0" wide run terminating at a 6'-0" wide x 5'-0" deep landing. Revit keeps griping at me regarding boundary loops. I've read through the standard tutorials, but I haven't had much luck yet.

Thanks.

The trick to ending with a landing is that the end must be a riser not a boundary. See the attached images or watch a short video (http://www.screencast.com/t/3DoE7XTzU0).

Thanks for the tip Steve,
I have often tried to make the top tread a landing, but not always got it working right - so this helps clarify it. I notice from your images that you do not have a blue "run" line, so I guess you created all the risers and boundries from scratch? A word of warning to anyone who uses the "run" command to draw the bulk of the stair: The blue "run" line controls where the automatic stair arrow is drawn - so it is really important that it stops on the last but one riser otherwise it is graphically wrong in plan (always the case for stairs that don't end with a riser).

Steve,
With your example, I get the landing to work just fine, but the handrail is troublesome - I have to set the railing lines to "flat" for the landing sections to get the top of the handrail correct. But how to get the base of the balusters at the correct height on the landing - they want to start one riser higher than they should.

Hard to say for sure without seeing the file but I find that I usually need to assign the segment of railing on the landing that doesn't play along to Flat, though I tend assign all of them to Flat as a precaution, favoring explicit rules over Revit guessing. With the attached image the railing settled down just by changing from by host to flat. In your image it looks like the balusters are not extending to the treads which implies that the sketch might not be over the stair enough to accommodate the baluster and railing offsets.

Great little tutorial - learn something new every day!

Thanks Steve
