    Reinforcing a Shape Edited Slab?

    Alright, so bear with me. Im not a Structural Engineer by trade, but ive been in Revit Structure all week, and now i have a question.

    I personally like the reinforcing toolset in RST. I can think of a few tools in RAC that should be built from the very same functionality (Wall framing, wall insulation, etc). Its the perfect blend of an array, a group, and loose and fast enough with the constraints that it DOESNT feel like "Revit."

    Ive also tried the REX Reinforcing, which i bailed on as soon as i moved a beam and the parallel bars unhosted instead of adjusting. Thats a deal breaker for me.

    Area reinforcing... Eh. I get that it gets the point across, but i wish it showed the bars the way regular reinforcing does (in 3d anyway) but i digress.

    Shape Edited slabs??? Not at all?

    Ive noticed that if i shape edit it so that it is UNIFORM, and i cut a detail section pependicular to the slabs slope, then (of course) the rebar works as expected, and i can get it normal or in plane with the work plane.

    But assuming a non uniform slab, you cant put ANY reinforcing in it AT ALL??

    Native reinforcing: Wont let you place it
    REX Reinforcing: Says its not a valid object.
    Area reinforcing: Places it on the level (work plane) so its out of the slab.

    Ummmmmmmmmmmmmmmmmmmmmm?

    We don't use any sort of Rebar in our model as of yet. However I just brought the topic up to the higher ups... we will see what they say. Anyways. I do not have a lot experience with reinforcment modeling.

    I am bookmarking this topic. Maybe someone else will have more experience, I am all ears.

      Well, i have a bunch of experience with the reinforcing tools, and they are great... In most normal buildings. Slab/Foundation connections, Slabs (placing the bars instead of using Area), etc... Its all good. i wish it was in the family editor and parametrically implantable, but thats another issue.

      But, i hadnt tried a warped slab until now, and im a little surprised it wont let me do ANYTHING. I knew it wouldnt get it right (after all, what IS right?), but i figured it would let me place bars, and they would poke out of one end, and id drag them back, and do smaller bars...

        Yeah I tested what you are saying... very strange that we cant warp the reinforcment... wish list time.

          I'm sure it has to do with slab reinforcing being planar and warped slabs not being planar. Revit doesn't know how to cope with that and have the reinforcing adapt. Floor hosted families won't work on warped slabs, either. Yes, this needs to be addressed. Maybe have rebar be somehow embedded in the floor slab families and assign size and spacing in areas of the slab with a different subset of sketching tools while in sketch mode. When the slab warps or changes thickness, whatever is embedded follows along with it.

            Don't understand how your having these issues, whether the slab is variable or not, as well as with the sub modify tools I had no issues with Rebar Parrallel or Perp.

              Then you arent making the same slab i am. Its not something we are all doing wrong, the program currently wont do it. I got confirmation from Autodesk that its not something im missing, the functionality isnt there yet.

              Id love to see a screen shot if you have a NON UNIFORM (complex slope) variable thickness slab, with reinforcing working correctly in it.

                If I model reinforcing in a slab and so much as hit the Modify Sub Elements Button, I get this:

                  Yup. Shape edit it first, and all you can do is Area reo, which lays on the work plane, not the slab. Oh well.

                    Unless I'm mistaken here is a warped flat soffit and variable with their own hosted reo one showing flat and the other curved.

                    Can you confirm I'm on the right track with yoru issue?

                    Also as for Area Reinforcement apart from showing some meshes I really dislike this tool, and not suprised it does not work.
