    Modeling Slab Edges

    for supported floors (not foundation slabs)...

    Up to this point we've detailing in the views as needed; detail components, masks, lines, etc. combined into groups and copied around to section views as needed.

    Now the architects want me to model my edges so they can see the geometry.

    I've been playing with the slab edge profile, but I cannot seem to get it to work at this time.

    What have you been doing?

    see attached. This is actually one of our standard detail views; all detail components, fills, lines, etc. Nothing is live. And, not all of this needs to be modeled.

    As much as I was trying to do, I could get the bent plate edge of slab. But, it wouldn't cut back the metal deck. Or, I tried a profile of a chunk of concrete, but it, also, wouldn't cut the metal deck back.

    I wouldn't mind having the bent plate, a chunk of concrete (that would mask the metal deck) and maybe a deck closure plate. A bonus would be the shear studs. At this point, I don't think I need the brick ledge, the reinforcing, nor the attachment bolt.

    I'd love for it to attach to the edge of slab (in plan) similar to the slab edge (turned down slab for foundation slabs) but be flexible enough for differing Edge of Slab dimensions (where X < 12".)

    At this point, this post probably needs to be moved to the Family Creation section. But my original post was just asking what everyone else is doing.

      I dont think that there is any think that will cut the deck profile that is associated to the floor. I only model slab edges at foundations. I use them to model the geometry from TOF to FF. Only ever used pretty simple profiles to do this.

        The example you have shown isnt really something you would do with a slab edge

        In that case I would look at either a line based family you can layout which you could set to framing or structural connection, or more likely nest in that component into the beam family

        You wont be able to cutback the metal deck either, the only way to do that is within the slab sketch

        But with either of the two first options you could mask the metal deck within the detail

          I know nothing about RST but this looked like an interesting modeling question.
          I modelled this using a railing with the 2 angles as rails and the angled supports as balusters.
          Also a conc. Edge profile tweaked to to get the radius.
          Little bit of trial and error but once setup just put conc. edge on then use railing tool and pick edge.
          It won't cut the conc. But don't you just offset the conc. Edge the desired distance ?
          Just thinking outside the square.... I must be bored....

            here's what I've come up with, so far...

            ~~ I have a profile to use for my slab edge. In it, I have a closed "outline" of the bent plate. I've also added a detail component.

            ~~ The Detail Component includes several filled regions (1 for the bent plate, 1 for the deck closure plate and one for the concrete and 2 for the continuous rebar) several masking regions (4 that make up the headed studs) and a few detail lines (3 to create the rebar.)

            ~~ When I placed the Detail Component into the Profile, I placed it so that the bent plate profile and the bent plate filled region are in the same place.

            My problem, now, is that the profile portion of the slab edge comes in at the correct location, but the detail component portion comes in above my slab.

            Any idea how to fix this?

              Hi,
              I did a small change in your profile family, the ref plane above the nested detail defines Origin.
              instead, check Define origin for the center front/back ref. plane.
              works for me, the detail position is correct; I picked the bellow edge of the slab when placing it.
              hope it helps.

              IMHO, your nested detail comp. should have a small masking region at the rounded corner bottom right.

                tried moving the "Defines Origin" to the Center (Front/Back) and while the profile now lines up with the detail component, they are now BOTH coming in above my slab... Hmmm.
                (ETA: I'm placing the profile as a slab edge, from plan view.)

                Right now, I'm just trying to get the thing to work the way I want it to. I'll go back and improve it later. ;-) I think I need to work on my concrete filled region, too. It's coming in on top of my masking regions (even though I sent the conc to the back and brought the headed studs to the front... )

                  did you try with above and bellow slab edges?
                  works for me for the bellow edge.

                    Once placed (with the "Defines Origin" set to Center (front/back) ) I can highlight the slab edge and adjust it's Vertical Profile Offset.
                    However, if I try to tell RST when I'm placing the profile that I want the Vertical Profile Offset to -6 1/4", RST ignores my request and places the profile above my slab. RST is making me take the extra step to move the profile down.
                    Also, my filled and masking regions are not working properly... Hmmm. Back to the drawing board... :banghead:
