Chapter 5 • Dimensioning and Annotating 214 7. Repeat the steps for the bottom of the corridor. 8. Add the rest of the dimensions, as shown in Figure 5.20. This will complete the dimensioning of the corridor area. FIGURE 5.19 Placing an angular dimension means picking two walls, then a point to place the dimension. FIGURE 5.20 Finish placing the corridor dimensions. If you would like to place the dimensions in different locations, feel free to do so. Dimensioning 215 The next set of dimensions will pertain to radial geometry. We can finally get out of this corridor! Radial Dimensions Radial dimensions are used to, well, measure the radius of an item. We are lucky that Revit knows that you are adding a radial dimension to a building component. This means the many different choices provided by a CAD application are taken away, leaving just the basics. The following procedure will lead you through adding a radial dimension: 1. Zoom in on the east radial entry in the east wing. 2. On the Annotate tab, select the Radial Dimension button. 3. Pick the outside face of the radial wall, as shown in Figure 5.21. 4. Place the radial dimension somewhere that makes sense. If your model looks like Figure 5.21, you may proceed. If it does not, go back and try it again. 5. Pan all the way to the west radial end of the west wing, as shown in Figure 5.22. FIGURE 5.21 Adding a radial dimension is about as straightforward as it gets. O Keep in mind that you can add an angular dimension to physically change the angle of the items being dimen- sioned. Use caution, however, and be sure the correct items are being moved when you alter the angle. Chapter 5 • Dimensioning and Annotating 216 6. On the Annotate tab, select the Radial Dimension button. 7. Dimension to the finished outside face of the brick, and place your dimension in a location similar to that shown in Figure 5.22. FIGURE 5.22 Adding the second radial dimension WARNING All too often, you can easily dimension from the wrong reference point. The reason this book is using a wall with a concrete ledge below the brick is to expose you to the fact that you need to be very deliberate in how and where you choose your references for dimensions. Don’t be afraid to zoom in and out as you add your dimensions. If you are careful in how you add a radial dimension, you will find this process quite simple. The next type of dimension, however, can be a little tricky. Arc Length Dimensions Measuring the length of an arc is a handy capability that was added back in the 2009 release. I have found the Arc Length dimension extremely useful in locat- ing items such as windows along an arc. That is, in fact, what we need to do in the west wing of the building. The following procedure will lead you through adding an Arc Length dimension: 1. Zoom in on the west radial entry of the west wing, as shown in Figure 5.23. Dimensioning 217 2. On the Annotate tab, select the Arc Length button, as shown at the top left of Figure 5.23. 3. Pick the finish face exterior face of the brick. 4. Pick the centerline of the window. 5. Pick a point along the exterior face of brick that runs along the verti- cal intersecting wall, illustrated as “3” in Figure 5.23. 6. Pick a point in which to place the dimension. FIGURE 5.23 Placing an Arc Length dimension involves four separate picks. Let’s try it again. This time the dimension will be taken from the first window (the one we just dimensioned) to the second window. The process will be exactly the same. 1. On the Annotate tab, select the Arc Length button if you are not still in the command. 2. Pick the exterior face of brick along the radial wall. 3. Pick the first window’s centerline. Chapter 5 • Dimensioning and Annotating 218 4. Pick the second window’s centerline. 5. Pick a point to place the dimension (see Figure 5.24.). Now that you have experience adding dimensions to record placement of items, it is time to see how you can physically use dimensions as a layout tool. FIGURE 5.24 Adding a second Arc Length dimension Using Dimensions as a Layout Tool When it comes to dimensions, using them as a layout tool is my favorite topic. “Okay, fine,” you may say. “I can do that in CAD.” Well, not quite. You see, in Revit you cannot alter a dimension to read an increment that is not accurate. You can, however, select the item you are dimensioning, and then type a new number in the dimension. At that point, the item you are dimensioning will move. The result is an accurate dimension. The first task we need to explore is how to equally constrain a string of dimen- sions. You were exposed to this task earlier in the chapter, but now, let’s really dig in and gain some tangible experience using this tool. To begin, open the file you have been following along with. If you did not complete the previous chapter, go to the book’s web page at www.sybex.com/go/revit2011ner. From there you can browse to Chapter 5 and find the file called NER-17.rvt. For this procedure, we will add some more walls to the west wing, and then con- strain them using the EQ dimension function: 1. In the Project Browser, go the Level 1 floor plan (not a ceiling plan!). 2. Zoom in to the west wing of the building. Using Dimensions as a Layout Tool 219 3. Select one of the interior corridor walls, right-click, and select Create Similar from the context menu. 4. Draw five walls, as shown in Figure 5.25. They do not have to be an equal distance from one another. FIGURE 5.25 Adding the walls “willy-nilly” 5. On the Annotate tab, click the Aligned Dimension button. 6. Also on the Options bar, be sure the justification is set to Center Of Core (see Figure 5.26). FIGURE 5.26 Changing the options for the dimension 7. Zoom in on the left exterior wall, as shown in Figure 5.27. 8. Hover your pointer over the wall. Notice Revit is trying to locate the center of the wall? In this instance, we do not want this (even though we just told Revit to do that). Chapter 5 • Dimensioning and Annotating 220 9. We want Revit to start this dimension string using the interior face of the finished wall. To do this, hover your pointer over the inside face of the wall, as shown in Figure 5.27. 10. When your cursor is over the inside face of the wall, tap the Tab key on your keyboard three times until Revit highlights the inside face of the wall. FIGURE 5.27 Press the Tab key to filter to the desired reference of the wall. 11. Pick the inside face of the wall. 12. Move your cursor to the right until you pass over the first interior wall. Notice the core centerline of the interior wall highlights. When you see this, pick the wall, as shown in Figure 5.28. WARNING Just like when we equally constrained the door in the previous procedure, you need to keep the Dimension command running. If you press Esc, undo the last dimension and start over. 13. After you pick the first interior partition, move to the right and pick the center of the next wall. 14. Repeat the procedure until you get to the last wall (see Figure 5.28). Using Dimensions as a Layout Tool 221 FIGURE 5.28 Adding a string of dimensions to the interior walls When you get to the exterior wall to the right, you will encounter the same issue. You want this string of dimensions to go to the inside face, not the core of the exterior wall: 1. Hover your cursor over the inside face of the wall and tap the Tab key on your keyboard until the inside face of the wall becomes high- lighted. When it does, pick the highlighted face of the wall, as shown in Figure 5.29. FIGURE 5.29 Press Tab to locate the inside face of the wall. 2. When you locate the inside face, pick it. Chapter 5 • Dimensioning and Annotating 222 3. Move your cursor up the view. Notice the entire dimension string is following. 4. Placing a dimension in Revit is a little awkward, but you will get the hang of it. You need to pick a point away from the last dimension in the string, as shown in Figure 5.30, almost as if you are trying to pick another item that is not there. When you do this, the dimension will be in place. FIGURE 5.30 Picking a point away from the last dimension to place the string Now that the dimension string is in place, it is time to move these walls to be equal distances apart from one another. Notice that, after you placed the dimen- sion string, the familiar blue icons appeared. We can use them: 1. Find the EQ icon in the middle of the dimension string and pick it. The slash through it is now gone and the walls have moved, as shown in Figure 5.31. 2. Press Esc twice to release the selection and exit the Aligned Dimension command. FIGURE 5.31 Before and after the EQ icon is selected If you placed the dimension string, then escaped out of the command, that’s fine. You can simply select the string of dimensions again, and you will be back in business. Using Dimensions as a Layout Tool 223 Because these walls are not constrained to always be equal, if one exterior wall is moved, these five interior partitions will always maintain an equal relation- ship to one another—that is, as long as this dimension string is still associated with the walls. In Revit Architecture, you can choose to keep the walls constrained or to use the dimension only as a tool to move the walls around. Constraining the Model Choices you make early in the design process, such as constraining a model, can either greatly benefit or greatly undermine the project’s flow. As you gain more experience using Revit Architecture, you will start hearing the term overcon- strained. This is a term for a model that has been constrained in so many places that any movement of the model forces multiple warnings and, in many cases, errors that cannot be ignored. Given that, how you choose to constrain your model is up to you. You will learn how to constrain (and of course unconstrain) your model in this chapter, but deciding when and where to constrain your model will vary from project to project. The string of equal dimensions we now have in place has created a constraint with these walls. To unconstrain them, follow along: 1. Select the dimension string. 2. Press the Delete key on your keyboard. ou t o F si g h t, ou t o F Mi n d In CAD, you typed E, then pressed Enter to delete an item. This is no lon- ger a good idea. If you do this to an item in Revit Architecture, it will only remove that element from the current view—not from the entire model. You are better off either selecting the item and pressing the Delete key on the keyboard, or selecting the item and clicking the delete icon, as shown in the following image: . walls, right-click, and select Create Similar from the context menu. 4. Draw five walls, as shown in Figure 5 .25. They do not have to be an equal distance from one another. FIGURE 5 .25 Adding. the wall. Notice Revit is trying to locate the center of the wall?
