Adding Slabs and Curtain Walls to Level One: A Comprehensive Guide

Adjusting Slabs and Curtain Walls for New Floor Plan Layout

Creating an effective floor plan involves making necessary changes and additions, as well as understanding how to properly align structures like curtain walls and slabs. This article provides step-by-step guidance, from making adjustments to the curtain wall, adding new slab portions, to finishing with the addition of a roof element.

Key Insights

  • The process of adjusting a floor plan often involves making changes to the curtain wall, ensuring that it aligns correctly with the slab. This is done by changing the view from hidden line to wireframe, providing a clearer view of the slab location.
  • When adding new slab portions to the floor plan, it is recommended to draw these as individual pieces rather than one sketch. This prevents accidental movement of different parts and ultimately results in a more accurate depiction of the structure.
  • Once these steps are completed, the next stage involves adding a roof element to the floor plan. This requires careful alignment and placement, similar to earlier steps in the process.

Let's go to our new Level 1 floor plan, and there are a couple of changes that we need to make and some additions that we want to do here. This is because we now have our floor slab, which will need to extend all the way out to here. When we create the curtain wall, you may have noticed that, because of its location, it’s probably hanging off a little bit, potentially depending on how you drew it. You can see mine is not quite on there—I missed them a little bit—and then I'm missing a little bit there as well.

So what I can do is go to that new Level 1, and I’ll temporarily change my view from Hidden Line to Wireframe. That allows me to have a better look at where that slab location is. Now I have the opportunity to make a quick change, which involves grabbing the curtain wall and moving it back from the face of the wall so that the face of the mullion aligns with the face of the slab. I'll do the same thing with the south portion.

This is where we can now go in and add the little bits of new slab that need to go underneath our new portions of the exterior wall. What I can do is actually select my existing one, and I can use Create Similar, and it will still create it on the right phase—because that's the phase we're in right now.

It's very tempting—I mean, very tempting—to just draw all of these as one sketch, but it's not a good idea. You might move one around a little bit without realizing that you're dragging another one around with it, including this little piece. So I highly recommend drawing these as individual pieces. It's really not that much more work to do that.

So you can see, drawing this one in, finish the sketch—it’s still selected, so I can hit CS and draw the next one in, which will be this piece here. Finish the sketch and do the same thing using the Create Similar tool to keep it moving. Now, when we look at it in 3D, you can see our slabs are lined up where they need to be, and we’ve got our little extension pieces shown correctly here.

So I’m going to go ahead and save again, because there are lots of things we don't want to redo, right? And then, one thing we haven’t done in a while—I’m going to Close Hidden Windows. Then we can go ahead and take a look at adding our roof element, and we’re also going to do something a bit tricky with these two walls on the exterior.
