Join Paul F. Aubin for an in-depth discussion in this video Using the Modify tools, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] Once you have some of the walls laid out, you might find it more convenient to actually use existing geometry to help you create new geometry. So we have a variety of modification tools that allow us to manipulate objects that already exist. And many of these are standard tools that you'd expect to find in really any kind of drawing program. Now, we're going to find them all under Modify tab, so I'm going to the Modify tab, and where we want to focus our attention is on the Modify panel. Now I'm going to look at a few of the commands on this panel and we'll see some of the other ones in future movies. But let's start with the Move command first.
It's probably one of the most basic commands. Now notice that the keyboard shortcut for it is MV. And if I leave my mouse here and wait for a moment, notice that a small animation will run. So what's actually really nice about each of the tools on this tab is that they all have these little animated tooltips. So I do encourage you to spend a little time and let each of those animations run so that you can kind of see each of the commands in action. All right, let me go ahead and click the Move tool. And because I click the tool first, Revit will next need to know what I want to move. So if you just say move something, but you don't tell it what to move, how does it know? So the prompt that appears on screen or down on the status bar is asking me to make a selection, and then press the Enter key to finish.
So let's say I want to move this wall. Until I press the Enter or the space bar to finish, it won't know that I'm done. So I'll press Enter here, and then it moves to the next step of the command. And the first question it will say is what's the move start point. And then it'll ask me what the move end point is. Now, you can do this in a variety of ways. But let's say I want to move this object over a distance that was equal to, say, these two points right here. I can pick the start point right here, and then the new point I can pick over here.
And what will happen is that wall will move by that amount. Now, if I look at that and I say, well, you know, that's probably a little bit too far, I can keep it selected and just go run the Move command a second time. So, here's the Move command. And this time, notice that it didn't ask me anything about selection because if something is already selected, it will assume that that's what you want to move. So I tend to prefer that second method over the first one. I like to make my selection first, and then run the command. Now in this case, I'm going to pick a start point anywhere in space, and I'm going to move my mouse in the direction that I want to go, and then just simply type in how far I want to move.
Maybe I want to go four feet. And that will move the wall back in the other direction four feet. So, those are two different ways to use the same Move command. Now, if you know how to move, then you know how to copy. So that's the next command over, and when I select it, the keyboard shortcut for that is CO. It's just base point and new point, and this time I get a copy. So, whether you're moving or copying, you're always picking it up at a location, and then putting it down at a location. And you can type in those numbers, or you can use the mouse to indicate those numbers.
Now, I've got this wall and where I really want it is actually down here. Now I could move it, but if I try to move it, notice that it will want to stay connected at the end there. That's just part of its behaviour. Well, with all of the commands, I want you to pay close attention to the Options bar when you're running these commands because many of the commands have additional options. And so one of the options right here is this Disjoin option, and that will allow me to move this wall and disconnect it from the other walls.
Now the other way that I could have manipulated that wall is to just simply use the little grip points at the ends. And I can drag this until it snaps to the nearby wall, and then it will go ahead and clean up that intersection automatically for me. So that's just a few different approaches you can take to starting with one wall and modifying it. Now, let's look at the Trim command next. So we've got Trim and Extend to Corner, and what this one does is make these nice corner conditions like we see right here.
So if I choose this command, and let's say I want to trim it back to here, it will create a corner condition right there and it will trim off this piece. Now if I change my mind and I want to put it back again, I can use the same command, and it will turn into an Extend command. So it's either a Trim or Extend in order to make a nice, clean corner. So I want to use that to actually create a small closet right here. We're going to enter the condo in this location, and right here, I want to put a coat closet.
So I'm going to select this wall, and this wall, and notice that before I click, it'll dash it in to kind of show me what I'm going to get, which could be really helpful to make sure that I'm getting the right thing. Now the thing you want to pay attention to with the Trim and Extend commands is the little prompt on your cursor. What it's telling you is to click on the part you want to keep. Now what that means is, if I use this tool again, there's really two possibilities right here. I could get this, or Ctrl Z to undo.
I could get this, Ctrl Z to undo. So how does Revit know which one I want? You pick the part you want to keep. So if I click on this side, it keeps that half. If I click on this side, it keeps that half. Let me undo. So what I want to do is offset a wall from here, at five feet away, and then use Trim to kind of trim it up with this wall. So I need a copy of that wall first. Now I could use the Copy command, but Offset is kind of nice, because it offsets a copy parallel to the original.
So it's a little bit easier to do it without having to pick the two points. So with the Offset command here, OF is the shortcut, I can set the distance that I want to offset how far away do I want the copy to be. I'll put in five feet. And then wherever you hover over an object, and move your mouse slightly, it'll show you where it's going to offset it to. So I want to hover over this wall, and make sure that I'm not getting it to go up. I want to hover it and move my mouse slightly so that it goes down.
And then I'll click, and it'll create a copy of that wall at a five-foot offset away. I'll switch back to Trim and Extend, and again, the shortcut for that is TR. Select this wall, and remember to pick the part you want to keep. So if I click up here, I would get the opposite of what I want. So I want to click down here somewhere, and then it would give me that. Now I'm going to click the Modify tool to cancel out of the command, and I'm going to select this wall. Let me pan slightly by holding my wheel in and dragging.
There is a temporary dimension here, and you can see that it's going down to a fraction of an inch here. Now, we could use the Move command again to enlarge the size of our living-room, but the fractions concern me because I don't really know how much round-off is taking place in that fraction, and I honestly don't really want to do the math. So when you know where you want the object to end up, and what distance you want it to have when you're done, the temporary dimension method that we've talked about in previous movies is the better way to go.
And I'm going to make this twelve foot six. Now again, to get feet and inches, we do "12, space, 6", or we do "12'6". And either way will give us feet and inches. And of course, when this wall moves, it stays connected here, so it automatically shortens that other wall. Now, I need two more spaces: a small pantry here, and a utility room over here. So I'll rough those in first with a couple of walls. Here and here.
And I worry about the size of those spaces later. But now I don't want this portion of the wall in between. So to do that, I want to look at another one of my modification commands. We've got the Split Element command here. Now, the Split Element command can work one of two ways. If you just simply click a point, and cancel out of the command, what you ended up with is two separate walls. Then you'd have to use Trim and Extend to Corner to clean up this piece and clean up this piece.
But what I'm going to do is to Ctrl Z to undo that, and remind you to look at the Options bar. So when I use the Split command, SL is the shortcut, notice that on the Options bar, there's a single option called "Delete Inner Segment". If I check that box, and then click here and here, it will automatically delete the part out for me in between. And then I'll go to Modify to cancel the command. So whether or not you want to just sketch the walls and rely exclusively on temporary dimensions to manipulate your layout, or whether you want to use commands like Move, Copy, Offset, Trim and Extend, or any combination of those, you have a variety of tools available to you to help you create your building layout.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
