A good floor plan starts with defining usable spaces with the help of walls, and being able to modify those walls as needed as your project evolves. In this course, Ed Cotey shows you how to design a space with interior walls, doors, and windows in Autodesk Revit. Design issues such as wall alignment, trimming and extending walls, and splitting walls to make openings and new wall types are also covered. You'll also learn to incorporate some aesthetic elements such as trim and crown molding and apply them to walls.

Topics include:
  • Drawing interior walls
  • Configuring wall height and alignments
  • Changing wall types
  • Aligning and splitting walls
  • Creating compound walls
  • Adding doors and windows
  • Working with the Family Editor
  • Adding sweeps and trims to walls

Trimming, extending, and offsetting walls

There are a few modification tools that are pretty useful when working with walls. My top three are trim, extend and offset. These are great tools to help you modify and place walls. You can use offset to create walls at a specified distance and at the same time as you're working, you may want to keep your working area clear and simple for the view. There's another thing that's useful in working with floorplans so that you can turn off or hide certain elements.

And that keeps your floorplan nice and clean. We're going to take a look at some of these tools. And see what you think of them. So, let's first of all go this first one up here. In the upper left corner, kind of zoom in. And we're going to first of all play with the trim command a little bit. We've got two situations, you'll see these to walls crossing here, and you'll see these to walls that don't meet. So, in order to make that work, go to Modify, and on the Modify panel, you'll find trim and extend to corner.

So, we're going to pick that. The first one is trim to corner, we're going to take the overlaps and I'm just going to click onto the inside of where I want it to trim, and you see it cleaned up that corner fairly nice. Now, to extend a corner, basically this wall falls kind of short, so we're going to extend it into this corner and it's going to shorten up this wall too. So, I'm going to click here and click there, and you'll see how it fixed it and made it work. So, that's how trim and extend corner work.

There's another tool up here as well, it's called trim and extend, it's a single element and you pick it. And in this case you pick where you want to extend to, so I'm going to pick this wall face. And I'm going to extend this single wall right into it. That's all there is to it. Makes it pretty straightforward. Now, I'm going to hit Modify. And the next case we have up here is we have three walls that need to be attached to this wall here in the center along gridline B.

So, what we're going to do is we're going to pick up this next one, which is for multiple elements. We're going to pick it and I'm going to pick basically the wall I want everything to extend to. And then I'm going to come over here and pick this one, this one and that one, and they're all extended. Come up here and click Modify and you can see that they're all put together. Now let's look at another situation where we have a issue where the walls are overdrawn.

So in this case, we would do the same thing with the same command. So I'm going to pick this, then I pick to the inside of the wall here, and then I'm going to pick to the inside here too. So I'm going to pick one, two and three. And then hit Modify. So on these two cases. You can use this command up here, which is called Trim Extend Multiple Elements to either shorten up walls or to lengthen them to meet a basic wall. The Offset command provides a very good way to create parallel walls at a distance that you go ahead and specify.

Now there's two methods to work with offset. One is numerical. Or you enter a distance. And the other one is graphical where you go ahead and you just kind of pick points. So, let's take a look at how that works. I'm going to come down to this location first. And we're going to first of all draw in a wall. So I'm going to come over here to architecture And I'm going to pick a wall type here and let's just pick up a generic 6 inch and we'll put it in on here.

Now I need to make some additional walls off of this. So, I can come up to Modify and pick Offset, and with Offset I can put up a numeric number. So if I wanted to come off a certain number, let's say I want to do 10 feet. And I'll do a copy of this, because if I don't have a copy it will move the wall. So I'll come over and if you notice that I'm on the left hand side and there's a little tracking line.

If I click there, it creates the wall. If I move over to the other side, it creates the wall. So now I have those extra spaces to work with. Go ahead and delete this one here. And this guy right here. And we'll play with again a little bit more. Let's go back into offset and in this case, let's turn copy off and I'm going to take this wall. And I'm going to move it over there, notice that it didn't make a copy of it, it just moved it over 10 feet, which is basically what you can do.

Now the graphical method works a little bit differently. I'm going to hit Modify and I'm going to come down here to this set of walls. And I'm going to pick offset. And I'm going to hit the Graphical. And notice that under graphical this is now turned off and I'm going to make copies of these walls. So, I'm going to pick this point here and I'm going to pull up. And that's my graphical method. So you gotta have some points that you want to work on. So, I'll pick this wall again.

And I'll pick the inside face here. And just move it over and notice what happens, it actually goes ahead and extends. So, that's how you would go ahead and use offset. It's very cool tool and another thing that you might want to consider is, if you look at this drawing in total. We don't typically use a lot of grids most of the time. And you might want to get rid of them. Now that doesn't mean deleting them, it means just maybe turning them off. So, one of the ways that you can do that is coming down here to the Visual Display bar and there's a little icon that says Reveal Hidden Elements.

Now, if you click on that right now, you get this red screen or magenta, and you don't see anything in here other than some grayed out stuff, which means nothing's been hidden yet. Go back down to the bottom and click it off again. And what I want you to do is pick up one of the grids. I'm going to pick this one up and I'm going to right-click and I want to pick Hide in View. Now in this case, I can do it either individually. In other words one element at a time or by category and in this case, I want them all off.

So, I'm going to pick category and now they're all clear. Now, I can turn them on any time I want by coming down here to reveal hidden elements. And you'll see here that they show up in the the magenta color. And again if I want to put them back on, I can click on one. Right-click and I can Unhide in View this time by category. And come back and click and there they're all back. So look at it kind of an on off thing.

If you're familiar with AutoCAD, it's like turning layers. Somewhat on and off. When you're working with walls, you can use these modify tools to finish off any rough edges in the design. The Trim Extend command allows you to trim corners. Extend to a single element or extend multiple elements. The Offset command, which is a very cool tool. Is unique since you can use either a graphical two point method or you can offset at a defined specified distance that you come up with.

Now while you're working, you can simplify your view by either hiding a single element or maybe a whole category of elements. You can then unhide these elements any time during your session. By just turning them either on or off on the visual control bar.
