Can't make monolithic stairs...

[Exar Kun]

Are there any particular reasons for getting this error message. I'm having an incredibly frustrating time trying to form the attached stair as a monolithic stair. It'll work as a standard one but either disappears or returns the error as soon as I make it monolithic...

Help would be really appreciated.

edit: attached stair parameters.

They can be difficult little buggers.

Have a look at the attached file. There is still a problem getting the last riser to fill in. Revit spits it out and that means you sometimes need to model the infill condition, if you don't have a convenient edge beam.

The factory are well aware of the problem with mono stairs and we can only hope that it is on the radar for a fix.

As ever, thank you Beegee.
