    Revit Precast

    Hi, I work with a relatively small precast concrete manufacturer based in the UK, producing PC stairs, & hollowcore slabs mainly.

    As part of our current design process We use Autocad, plus a custom Autocad add-on to help with the PC unit designs and to generate schedules and make sheets etc.

    We've used this add-on/ process for many years now, but are starting to acquire jobs that will issue Revit models and ask for a BIM compliant model of our slab/ stair layouts.

    We have recently purchased our first Revit licence and will start the process of training up a member of staff in the new year with the aim of the entire office being BIM compliant in the future.

    I'm seeking some advise from users that may be involved in a similar setup.

    Does anyone have experience using Revit in this way... for the design and manufacture of PC stairs & hollowcore slabs... Are you using Revit add-ons like AGACAD Precast Concrete, IDAT, or even Autodesk's recently released precast module for Revit as part of your design & manufacture process?

    If you gonna use only Revit - by default in Revit family library there is Structural Framing (beam) families for hollow core slabs. So you draw them as line based elements, dissallow joints at the ends and then copy them all over your building. Make openings with openings By Face or Void facebased families. Makes schedules, plan views as necessary. Make assemblies if you need drawings of individual slab.
    Stairs in Revit - two ways - can be created by sketch or stair by component. What's wrong with stairs by component - you can't create assembly. But I am not sure if any of these will help you. So what I know from other guys - they create line based families to fit exactly the shape they need for the stairs and landings. Also if you create assembly, probably you will need to rotate crop views or assembly origins to represent the drawings in the way you want.
    Autodesk precast - it's for walls and slabs. Should be fine for hollow core slabs probably.
    IDAT - can't comment, didn't try that, watch youtube and compare to Autodesk Precast. I think most of it related to slabs are already transfered in Autodesk Precast.
    AGACAD Precast Concrete - can work with all categories and is flexible with details and drawings. Watch webinars on youtube about Precast Floors. Contact them and have a demo online.
    So for precast floors I would say there is something to choose from, for stairs - not a lot of choices. At least that's how I see it.
