Revit Structure Framing Modifications: Coordinating and Modifying Structural Elements

Hello and welcome back to Revit Structure. Let's get started. Now that we've coordinated our new elements into our structural model, let's look at the modifications of the framings we have to do.

Okay, let's go to our new stair. We find we have a new shaft opening here, so let's frame around it. What we want to do first thing is go to our structure tab, our structure panel, and our beam tool.

Let's pick that. Okay, we find we have a 14 × 22, which is adequate for this job. Let's place it.

But first, let's check the parameters. We find it's referenced to level two, which is where we want it to be, and it's five and a half inches below finished floor. That is correct too.

We have no start or end connection here or here, so we're good to go. Let's start placing. First thing we want to do is intersect this beam, place it, extend it to the next beam closest to it here, and do the same thing in this direction here and here.

Now that we've framed this beam, let's escape out of it. Let's go to modify, and let's look at our levels above. Let's go to level three.

Let's pick it twice. Here we are. Now we see our architectural model is not backgrounded yet, so let's do that right now.

Let's go to VV. Let's go to rivet links. We see our visibility is checked on.

Let's do a half tone so we can make it a true background, and let's go to display settings. Pick that, and in our next dialog box, what we want to do is we want to link this third level by view, so let's pick this, and we see the linked view right now is the high roof. We want it to the third level, so let's pick here, do the drop down, find our floor plan level three.

Let's pick that. Let's hit okay here and okay here, and there we have it. There's our architectural background.

First thing we want to do is we want to create a cantilever to this grid line so that we can move our existing beam element to this line. Okay, let's get started. First thing we want to do is we want to again go to our structure panel and our beam.

Let's pick that, and again we have our 14 × 22 showing, but that's a little light, so let's find something a little bit heavier. Let's pick that, and we have an 18 × 35. Let's use that one.

Okay, we find now that our reference level is level two, and we actually want it to reference level three. Let's check our offset value. Here it's at five and a half, but that was true for the floor below, not this one, so let's change this because we have a three-quarter inch plywood sheathing on this floor.

Let's pick this. Let's change it to a minus three-quarter inch. Okay, and we do have a start and an end condition.

Okay, let's place this here, stretch it out to here. Let's modify this. Let's pick it and change our start connection here to a cantilevered moment connection.

There we go. While we're here, let's change its structural usage. It's not a joist, it's now a girder because it's going to be picking up our existing beam.

Okay, let's move our existing beam out to this grid line E9. First thing we want to do is we want to go to our modify tab. Let's pick it.

Go to our modify panel and find our align tool. Let's pick that. Okay, we want to place this beam on this grid line, so the first thing we want to do is pick our grid line and now our beam.

Get an error message that says we can't keep these elements jointed. That's okay, let's unjoin them because we're now joined to two new elements. Okay, now that we have that beam in place, let's exit out of that or modify and get out of that command.

Next thing we have to do is we have to modify our beam system. So let's find it, let's pick it, and up comes the contextual tab, and we want to go to the mode panel and the edit boundary. Let's pick that.

It changes our boundary element into a modifiable element. So what we want to do again is we want to go to our modify tab and panel and pick our align command. Now what we want to do is align our boundary to our beam.

So let's pick the beam and now the boundary. Now that that's done, go to our mode panel here, check okay, and there we have the modified beam system. As you can see, it's come in with a couple of new w12bys.

Let's delete those, and now let's modify this area to accommodate our new stair opening. Okay, what we want to do is we want to pick these elements and unpin them. Okay, now we want to place a new element here.

Well, our element is a 2x12 piece of dimension lumber. So again, we'll go back to our structure tab, let's pick it, our structure panel, let's pick it, and it sees four joists as beams, so let's pick that one. Okay, here we have an 18x35.

Let's look at our options in the wood. Okay, we know it's dimension lumber, so let's scroll up. We've got a 2x12 here, let's pick that.

Let's come in here, let's place it here to here, and we want to use a double joist here, a double stud. Let's pick it again, let's offset it by three inches, let's pick it, place it. Okay, let's modify that command, escape out of it.

Now, what we want to do is we want to shorten these existing joists to this new joist we've just placed. So what we want to do is we want to go to our modify tab, and we want to go to our trim, extend multiple elements. That way we can trim all of them and not just one at a time.

We'll pick our first element we want to trim to, which is this one. Now we'll pick the element, and this is a side that we want to keep, so let's pick it. It takes a moment to read it.

Pick it. Okay, let's modify out of that. Let's copy one of these, because it didn't fill that space.

Let's pick it and go one foot four inches over, place it. And there we have our new framing for our stair. Now let's pick these elements, and let's pin them.

Okay, that takes care of the third level. Let's zoom out. Let's take a look at the 3D elements we have.

Okay, let's pick a view. Let's zoom around to the other side where our stair is. And there we have our stair elements modeled.

Very good. Now we have three other levels, or actually two other levels we need to modify, level four and five. Okay, let's get out of this view.

Let's go to level four and five. Let's go to level four first. Again, we see we have our background not in there, so let's pick bb and go through the same steps.

Revit link, halftone by host, linked view, again the high roof. We want level four. Very good.

Okay, what we want to do is we want to delete all of these elements, because we're going to copy them up from level three. Let's go to level five. Okay, let's background this one.

Again, we have our visibility set, halftone, custom, link by view. This is correct at level five. Let's hit okay.

Now let's delete these elements. Okay, let's go back to level three. Okay, we have a beam system here.

What we want to do is we want to grab these joists, our new double joists, and our newly modified elements here, and our new cantilever, and the beam where we replaced it. Okay, now that we have that, let's grab the beam system too. What we want to do is we want to go to the modify tab, the clipboard.

We want to copy this to clipboard. Okay, so now let's make our job quick. Let's go to paste and the drop down, and we see we have a couple of different options that we can use.

We can just paste from clipboard, align to selected levels, align to current level, which we don't want to do, align to selected views, same place, to a pic level. Well, let's go to align to selected levels. Okay, that gives us a dialog box here.

We know we have level three set, so let's go level four, level five. Let's hit okay. Very good.

Let's take a look at our new levels to see if our copy and paste worked. Let's go to level four, and there we have it. We have all of our framing in.

Did it once and copied it to two levels. Let's check level five. There it is.

We're finished. That's it for this video. We'll see you in the next one.
