    Underground Construction...

    Hello,

    I'm trying to build an underground garage to one of my project, which will partly under the building, and partly under soil.

    So the question is, how do I implement this into my 3D Model?

    I've created a toposurface, and split it/used pads. That gave me the excavated part. But I don't know if there is a way to fill it "partly"?

    I've attached a sketch of what I want:

    Any ideas?

    Sorry, won't work with topography. Masses or floors are often (ab)used to achieve this result.
    There must be a better way...

      Any way to do it with 2 different topos? Cut one, then "fill" in the areas with another? Might even be able to join them?

      Or fill it in with an in place family? Just throwing out some ideas. Haven't tested anything.

        As I remember, I can draw separate types of surfaces on top of floor slabs, right? So, as I'll need to landscape as well, this will be my choice.

        I forgot to add, this is an Airport project that we are doing at school. Also, this is my very first full-scale project of Revit.

        I'll let you know the outcome.

        Thanks, ekkonap and dzatto!

          The attached image illustrates how this view can be done:

          1. Main topography (green dashed line) is placed at the highest level (set the depth of the earth pattern below the lowest level).
          2. 2nd topography (red dashed line) is a split surface of the first one, moved to the lowest level.
          3. 3rd topography (blue dashed line) with the shape of the area that you want to infill, is placed at the highest level.
          4. A building pad (orange dashed line) with the same shape of the 3rd topography, is placed at the top of the garage (intermediate level).
          5. With Visibility Graphics, set the Topography category in this view to Transparent.

            I don't think that will work with a Pad underneath.

              Well, I've used the Floor and split surface tools instead. Seems enough to me for this particular project... Looks like a straight cut was sufficient After all.

              However, many thanks to Alfredo Medina. I'll keep your information for future reference.

                A colleague from California has brought to my attention that the procedure described in post #5, above, (from January 2012), which used to work so well when I posted this solution, no longer works with the recent versions of Revit. True.

                The only reason I can think of, is a change in the Visibility Graphics window at some point between Revit 2012 and Revit 2013 in regards to transparency. If I remember correctly, the Visibility Graphics window had the option for transparency as a check mark (as shown on the image above), and, starting from Revit 2013, transparency is set with a slider from 0 to 100. That could have affected this trick.
