Creating or Editing Stair Families

[Anonymous]

I'm fairly new to Revit and I'm having an issue editing or creating a new stair family.  The company I started with a few months ago gave me the task of creating a stair the more closely mimics what we design and detail.  We have a 7" rise and an 11" run.  The part of the steps that are causing me issues is that the top tread needs to be 12" and the bottom tread needs to be 23".  I have not been able to find a way to edit individual treads in the stair properties box or the "edit stairs" tool.  I've tried adding landings to the top and bottom of the stairs but when I do that Revit throws handrail around the entire perimeter or the stair and landing and will not let me erase the sections of the handrail I would need to.  I'd love to ultimately create a new stair family that just brings the top and bottom tread in as they should be, but I'm not sure if this is possible.  I've been in the "Stair and Railing System Family Library" file but it doesn't seem like this is the  base file for the different types of stairs.  When I search through the file explorer in the Revit families folders the Stair family folder that shows up in the project browser with in Revit is not present in the file explorer for me.  This is after I've "show hidden items" in file explorer.  Anyway, I'm stumped and any help would be appreciated.  Thanks

Revit makes a difference between loadable families and system families. System families are part of a project and can be only created  by duplicating an existing one and changing parameters (or copying from a different project). So you will not find them in a folder.

There are different options to get to what you want.

You can first create a stair with fixed tread depth. When thet is ready  you can convert it to a sketch based stair and the modify the tread depth of some of the treads. Or you can start with a sketch based stairs from the start

In several cases the stairs tool is not sufficient to get to the desired end result. In those cases you might need to (partially) create the stair with one or more loadable families or in place families.

Thank @L.Maas this gets me closer to what I'm looking for.  So I now have the top and bottom tread the length I need them.  Now is there a way to get the bottom of the stringers mitered as I have sketched in below, rather then cut as they are?

I do not tink you can solve this with the stringers from the stairs tool.

I might use beams (structural framing families) for this

Thats what Im looking for!  Thank you.  One last request though.  How do you model beams as stringers?  Or model sloped beams?  When I go to model a beam I have to select a reference level which then seems to lock it onto that plane.

Set your workplane first before drawing the beam

@L.Maas Thanks for all your help.  I was able to get the outcome I was looking for.  I really appreciate it.
