    Hi Iyke29, as far as I can see on your image you'll can cut those by putting some voids and by attach them using reference planes, seems not complicated at all! regards

    Can't you model that as a single extrusion with that shape, without cutting anything?

    You need to make a face based void family and then call it in your desired family and put it on the face you want.

    Yea, thanks guys if finally did it using the voids command, i encountered yet issue with the concrete floor that should come right on top of the foundation. It has several slanted points meant for drainages, how do i model this several high points and lower points. Thanks in advance guys....sorry i am new with using revit ....just couple of months old....say 6 months

    Hi Again, you need to edit your slab "sub elements", to do that you pick the slab then on the ribbon you'll find an option called "modify sub elements" this allow you to add individual points or lines which can have different heights, those heights can be controlled by a grip or by entering a value, hope this helps

    Hi again Iyke29,

    I understand your issue, in your case is still doable by using a void to cut the floor, you'll need to do as follows:

    1. Create a Reference plane and name it (the reference plane is necessary to define the plane to create the void extrusion which will cut your slab)
    2. Create an in place Void component and put it in the Floor Category
    3. Create your extrusion and by hitting the cut button cut your slab with your void (See images)
    I guess that's all you need to cut your slab, regards

    Even if this is possible I find that is unnecessary since you can do the same without having a nested family!

    Isn't this whole process better off just using slab edges?
