    Metal Stairs...

    The image below is a metal stair taken from a manufacturers technical manual which I've now got to create.
    I don't normally get involved with metal stairs but I have seen some images on here of metal stairs and I wanted to get users thoughts on how best to achieve this:



    I tested out using the default stringer but could get exactly as per the image; I can get the horizontal cut at the upper floor level but not the desired projection below which I imagine would need an additional family (sounds messy to tack little parts onto the system family stringer). I'm also unsure if I can replicate the 1/2 tread and start and bottom of the landing WITHOUT having to sketch the stair.

    My gut feeling based on recent experience with assembled timber staircases is that I'm likely best to once again use walls for the stringers and sketch the run but if its achievable by component, I'd prefer to go down that route.

    Does anyone have any links to tutorials for metal sloping risers??

    Got close... the little bit at the bottom can't do.
    If it's got to be exact, then I'd go Generic model with the understanding it won't cut like a stair in plan. Or GM the stringers since the run is doable.

    Hi Chris, thanks for taking a shot at it. Did you do the run by component or sketch?

    What would be your reasoning for choosing GM over a wall (for the stringer that is)?

    Started with component, couldn't do the half treads so converted to sketch so I had freedom to control the tread depth.

    All depends on how detailed you need to get, scheduling purposes, visualization etc.

    250x8 I'm assuming is a Steel C shape, so I'd want the ends closed off with plate to keep the flange continuous, which you can't do with a wall. If all you want is a boxed in stringer, ya a wall could do it. I prefer to let walls do what walls do best... being a wall

    Or it's good enough and allow that little downward stringer piece to be corrected in details.

    Its just a flat plate stringer. I could do GM's but its a lot more work to set all the different types needed whereas I walls as its quick to achieve the necessary look to be seen in plans and sections.

    It's looks like my initial suspicions were correct and that I'll likely end up using walls for stringers and sketched runs as you did yourself.

    Cheers

    Just to add a few cents...model in place has had stairs as a category since v17. Before that here's a hack..
    Proper In-Place Revit Stairs: it's possible! - IMAGINiT Building Solutions Blog

    Either way remember MIP will not host railings properly.


    Btw, I despise MIP. Hurry up Parallax team and release your really cool tools.

    Cheers for the link Elton, I wasn't aware of the IFC hack but I'm on 2018 so I guess I wont need to use it.

    I too hate MIP and avoid it where possible. The reason I wouldnt use MIP for stringers is the number of different MIP components which I would need which would start to pollute the stairs category of the Project Browser. At least with a wall, I can cater for all lengths/stair pitches/ storey heights etc.. and only have 1 single entry in the PB.
