Adding dimensions


Revit Architecture 2015 Essential Training

with Paul F. Aubin

Video: Adding dimensions

In this movie we're going to look a little closer at the dimensions feature in Revit. We've already looked at dimensions in a few other movies, but mainly we were interested in using dimensions as a tool to help us build our model. In this movie, I'm going to focus on dimensions as an annotation tool to actually help enhance our construction documents and prepare drawings for printing. I'm in a file called Dimensions and I'm looking at a level one floor plan view. And I'm just going to add some dimensions to various parts of this file here just to show you how it works. So what I'm going to start off with is, I'm going to zoom in over in this location over here.

Viewers: in countries Watching now:

Build your Revit skills from the ground up. In this course, Paul F. Aubin teaches you the core building information modeling (BIM) techniques you need to complete solid architectural projects in Revit 2015. 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 get to modeling: adding walls, doors, and windows; creating and mirroring groups; linking to external assets and DWG files; and working with floors, roofs, and ceilings. Paul also shows advanced techniques for modeling stairs, complex walls, and partially obscured building elements, as well as adding rooms and solid geometry. Finally, discover how to annotate your drawing so all the components are perfectly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.

Topics include:
  • What is BIM?
  • Understanding Revit element hierarchy
  • Navigating views
  • Creating a new project from a template
  • Adding walls, doors, and windows
  • Adding plumbing fixtures and other components
  • Linking AutoCAD DWG files
  • Rotating and aligning Revit links
  • Working with footprint and extrusion roofs
  • Adding openings
  • Adding railings and extensions to stairs
  • Creating stacked and curtain walls
  • Hiding and isolating objects
  • Adding rooms
  • Creating schedule views and tags

Adding dimensions

In this movie we're going to look a little closer at the dimensions feature in Revit. We've already looked at dimensions in a few other movies, but mainly we were interested in using dimensions as a tool to help us build our model. In this movie, I'm going to focus on dimensions as an annotation tool to actually help enhance our construction documents and prepare drawings for printing. I'm in a file called Dimensions and I'm looking at a level one floor plan view. And I'm just going to add some dimensions to various parts of this file here just to show you how it works. So what I'm going to start off with is, I'm going to zoom in over in this location over here.

And I just want to show you the basics of how the Dimension tool works. Now we've covered some of this, so some of this will be review. We can get to the Dimension tool in a couple places, we can go to the Annotate tab and there actually are several dimension tools. I'm going to focus on the Align dimension tool because this is the one I use 99% of the time. So you're free to explore some of these others on your own later. They all kind of work the same way. But I'm going to focus on the Align tool. What the Align tool does is it's aligned with the geometry you're dimensioning, so it's probably the most versatile. So I'm going to click on that.

And that same button is right here and the shortcut is D+I. Now, when you highlight an object, it will highlight some part of that object. Now with walls, we actually have some options. So here you can see that if I put my cursor over it, it's highlighting the face of the wall, and if I move slightly it gives me the other face of the wall. So if I wanted to say what the inside dimension of this office was over here I could click this face, and then this face. And then if that's all I wanted was just that single little dimension, the third click, the final click is in empty space. If you click an object and click another object, and then you try and click in the same spot to place it, it will actually remove that witness line.

So each time you click, Revit is looking to either add or remove a witness line. And I see folks struggle with this a lot. They'll click a point, and then they'll click again in the same point and they'll wonder what happened and then they'll click it again and then they'll do it again. Remember that the final click, placing the dimension, has to be in empty space. There has to be no object under your cursor because that's how you're telling Revit, put the dimension here. If there's an object under your cursor, Revitthinks you're dimensioning that object. Now, here on the Options bar we have some settings. So instead of wall faces, if I wanted to, I could dimension the centerlines of the walls.

So if I choose that, now you'll see it will highlight the center of this wall, and the center of this wall, and I'll get a different dimension. So that's certainly an option. Well, if you want to, you could actually do the center on one side. And over here I could say I want to go to the outside face, well how would I do that? Put your mouse over the outside face and press the Tab key. Even though you've chosen your preference on the drop down there, you can still override it anytime with the Tab key. So you just Tab until the object that you want to dimension highlights and that's when you click to verify that selection and then of course I can place the dimension.

So those dimensions there I'm just using as sort of warmup to kind of get us started. Let's Zoom Previous to get back out to the overall plan here. And let's go a little deeper. The other thing that we can do, all of these examples I did in here were just individual dimensions, just between two points. But I wanted to also make sure that you understand that you can select two points, like these two grid lines, and then keep going. And so I can make a continuous string of dimensions by just continuing to add more and more dimension references, and again it ends the same way as the previous ones.

You click an empty space to finish it. So those are the basic mechanics of placing the dimensions, but let's take it a little deeper now. If we look up here on the Options bar, under this Pick option here, there's two choices. And we've been doing the individual references, but we also have this feature here called Entire Walls. Now what's handy about this is you can select the wall now instead of the two sides that you want to dimension, and Revit will figure out where the two witness lines should go, it'll do the whole wall. Now, in this case I'm just getting one wall end to end.

Maybe not exactly the dimension I had in mind, but there's an Options button right here, and if I click that, we have a whole bunch of options here that we can look at. So we can include the openings when we're making that dimension. You can dimension to their center lines, or their widths. I personally like the widths. So let's take a look at that. I'm going to click OK. Let's zoom in down here. Pick this wall. And look at that. Now, that's going to be a big time saver. Because if we did the same thing with individual references we would have to click each one of these points to get to that location.

Now, you notice how I still have a wall centerline here. So it was picking up the centerline. So these two work together. If I go to wall faces, zoom out just a touch, pick this wall. Now you can see that that final dimension is going out to the face of the wall. Let's zoom all the way out. I'm going to do Zoom To Fit, Z+F. Let's go to Options again. If you want to, you could add the intersecting walls in your dimensions. Let's see what that looks like. Now i tend to think this is just a little too busy for my taste.

There's an awful lot of going on here, but let's say you did like this and you want it to go with that. I'm going to cancel out the command. You can't read any of these dimensions at the current state. So if you click on the dimension, there's these little dots right here, these little grips, and you can use that to drag the text away. Now if you drag it far enough, it will actually add a leader pointing back again. You can have that leader point back and that makes it, I think a little bit more legible. So if you started to pull all of these labels away, you could start to make this dimension a little bit easier to read.

But I'm actually going to delete this dimension and zoom back out agai, and do it slightly differently. If I go to Options, I'm going to turn off the intersecting walls, but I'm going to turn on intersecting grids instead. And let's take a look at that. Now when I click this wall, it's a little bit less busy. It's including the grid line here and the grid line here. And then the rest of it kind of ignores the interior walls. I tend to prefer doing a different string for the interior than the exterior, so you can see that it's a little bit cleaner. You may still need to move a few of those pieces of text over there.

Now lets pan it over here. What about this wall here? The only downside of Pick Walls feature is that you can only pick one wall at a time, but you can select an existing dimension, and then up here on the ribbon we can choose Edit Witness Lines. Now when I click this button, this just takes me back into a mode where I can add in more dimension lines. So I'm going to add a witness line here at the end of the curtain wall, one here and here on each side of the door, one over here at the outside edge of the wall. Now, the final click has to be an empty space, just like we did when we were creating the dimension in the first place.

So don't press Escape or Enter here, you'll lose all your work. Click in the empty white space, and that will complete the dimension. And you now have this continuous string here. Now, let's say that, for whatever reason, I wanted to exclude this line right here. I want to basically break this dimension into two pieces. Highlight the dimension, press your Tab key, and it will actually let you reach in and pick an individual segment. You can click on it, and then you can just delete that. And now I've got this dimension, and this dimension has two separate dimensions.

So, that's a handy new feature because there really was no way to do that before. You'd have to delete the entire dimension and start again. I'm going to undo that and get that one back again. Another really neat feature that we can do, is we can edit the text value. So let's say that this curtain wall is existing and we don't know exactly how big it is. I can click right on the text and what this is, is you're editing the dimension text now. And the actual value is this 17'10'' but we can replace that with an alternate value like VIF for verifying field.

And it will replace the numerical value with the text value. Now, you can't put in a number here. Revit will not be happy about that. In fact it will display a dialog and tell you that that's not allowed. So, this can be replaced with text, not with a number. So, I'm going to go back to use Actual Value, and you can actually add modifiers on any of the four sides around the text as well. So maybe you want to say that it's close to 17'10" but you want them to verify, so you can add the note below or something.

So let's zoom all the way out and check our work. There's nothing like some dimensions to make a drawing start feeling like a construction document. So, we're getting close to being able to print this drawing out. So, feel free to experiment further and add additional dimensions. Remember that you could either do the individual references to the faces or the centers. Or you can use the Pick Walls option to do the entire walls. Pick Walls is only available for walls. So if you want a dimension between plumbing fixtures or other elements like columns and so forth, those you'll have to do with the pick references.

Q: Which versions of Revit should I use with this course?
A: This course is written for users of Revit Architecture 2015 and Revit LT 2015. Because Revit LT does not have all of the same features as Revit Architecture, some movies in this course will not be relevant for Revit LT. Additionally, there are some topics that are relevant in both versions, but the button layout or location of those tools are different. In those cases, the features and procedures for Revit Architecture are shown in the course.
Q: Which content in this course is different or not relevant for Revit LT?
Chapter 2 – Accessing Revit Options (There are some slight variations in the option dialog in LT. Not all options shown are available in LT.)
Chapter 3 – Accessing a multiuser project using worksharing (The worksharing feature is not available in LT.)
Chapter 4 – Using modify tools (LT has a slightly different ribbon layout, but most tools covered should work the same. Some buttons will be located in slightly different spots.)
Chapter 5 – Establishing shared coordinates (The shared coordinates feature is not available in LT.)
Chapter 6 – Using the shape editing tools to create a flat roof (The shape editing tools are not available in LT.)
Chapter 7 – All movies (Sketch-based stairs are not available in LT. LT only has component-based stairs.)
