Simply put, if detailing doesn’t work, then you’ll use Revit only as a schematic design application. It’s imperative that you can detail in Revit efficiently. When firms fail in the attempt to use Revit, it’s because of detailing. In fact, many of you who have bought this book may jump straight to this chapter. And why is that? It’s because many people (including me) buy into the concept of really cool 3D perspectives and one-button modeling. So, here’s what we are going to tackle in this chapter: When you understand Revit, you find out immediately that the real hurdle in getting it to work lies in the detailing. Sure, you can cut sections and create callouts, but how do you add that fine level of detailing needed to produce a set of documents that you’re willing to stamp and sign? This chapter addresses the issues surrounding detailing. The first thing that comes to mind when dealing with CAD standards is line weights, right? In AutoCAD it’s layers, in MicroStation it’s levels, but on paper it’s line weights that control 75 percent of a company’s standards. As you’ll learn in this chapter, Revit can be a good 2D drafting application as well. As you learn how to control line weights in the 3D elements, you can also control line weights, well, line by line. To begin, open the file you’ve been following along with. If you didn’t complete the previous chapter, go to the book’s web page at The objective of this procedure is to format the line weights and to see where, and how, they’re read by Revit: FIGURE 12.1 Object Styles is located at left on the Manage tab. FIGURE 12.2 Changing the object line weights Glancing up at the headers that describe the columns, you see the Line Weight column. This column is divided into two sections: Projection and Cut. The Projection column controls the line weights of objects as they’re viewed in plan or elevation. The Cut column controls the line weights as they’re shown in section. So, to reiterate, projection means plan and elevation, and cut means section. Your objective is to modify the line weight for both the cut and the projection of the roof. FIGURE 12.3 Your section’s outline should begin looking a lot better. Now you can start adding your own items to the section. The next group of procedures focuses on inserting and creating detail components to use in the sections. As mentioned before, Revit provides a good number of 2D details that you can insert at any time. When Revit doesn’t have the component you need, you can always create one. It isn’t that hard to do. In this section, you’ll physically create a detail. The procedures you’ll apply consist of adding detail components, linework, and filled regions, and doing some good old-fashioned drafting! The first procedure focuses on inserting predefined detail components. The great thing about this is that you do nothing that you haven’t done repeatedly throughout this book—it’s just a matter of finding the right button to get started: FIGURE 12.4 The Load Family button on the Mode panel of the Modify | Place Detail Component tab The next step is to simply start drafting. As mentioned earlier, you’re only going to get so far with 3D modeling before you have to take matters into your own hands and draft. The way you can approach this in Revit is to take the parts of the detail you want to keep and hide the rest. After you hide portions of the detail, it’s time to begin adding your own ingredients such as detail components and lines. FIGURE 12.5 Placing the break line, and flipping the component To let you hide portions of the detail, Revit has added a nice feature called a masking region. Instead of wrestling around with items you ultimately have little or no control over, you can hide these items to make way for your detailing. To learn how to apply a masking region, follow these steps: FIGURE 12.6 Region The area is now masked. The problem is, though, that some areas such as the break may be a little too masked. The next procedure steps through changing the display order of a detail’s objects: FIGURE 12.7 Click the Rectangle button on the Draw panel, and place a masking region as shown. Your detail should now look like Figure 12.9. The next step is to add a brick face. Yes, Revit showed the brick before you masked it, but you need to show coursing, as well as how the façade is tied back to the wall. To do this, you’ll use a function called a repeating detail. FIGURE 12.8 Click the Bring To Front button on the Modify | Detail Items tab after selecting the break line. FIGURE 12.9 The detail with the completed masking region Revit has a technique that allows you to add a detail component as a group. You do this by basically drawing a line; Revit then adds the detail in an array based on the points you pick. To learn how to add a repeating detail, follow this procedure: FIGURE 12.10 Select Component FIGURE 12.11 Adding the repeating detail based on the points shown Your detail should look like Figure 12.12. FIGURE 12.12 The first repeating detail Next, you’ll keep going with the repeating detail. The problem you’re faced with is that you need to deal with the soldier course in the exterior wall. You can add that in a moment. Right now, complete the brick down past the break line. If you feel like you’re getting the hang of adding the repeating brick detail, go ahead and add the second repeating detail. If you would like some instruction, follow along: FIGURE 12.13 Picking two points FIGURE 12.14 The bricks are being placed. The next step is to add the soldier course. You’ll do this the same way you added the break line. In this respect, Revit offers a good library broken down into the CSI format. To add the soldier course, follow along with the procedure: FIGURE 12.15 Placing the new detail component Well, the soldier course is in place, but that fat line weight is horrendous. It would be nice if everything that came out of the Revit box looked nice and met your specifications; but alas, that isn’t the case. It’s time to modify this component to make it look presentable. Right about now is when every CAD/BIM manager around the globe raises an eyebrow—for good reason. Revit allows you to modify a component by actually opening the file! But don’t worry; you have to issue a Save As to save the detail. The objective of the following procedure is to create a texture on the brick detail and to use a line weight that the user can control in the model: FIGURE 12.16 Open the family for editing after selecting the detail component. The detail component family is now open. It’s time to operate, Doctor. The next set of procedures will focus on modifying the linework of the brick and adding what is called a filled region. A filled region is similar in nature to a masking region in that you apply both in the same manner. A filled region, however, contains a hatch pattern that is visible when the region is completed. This is how you hatch in Revit. It takes the place of the conventional hatch command found in AutoCAD and MicroStation. The objective of the next procedure is to modify the filled region that makes up the brick. You’ll also use the region’s outline to define the perimeter and the texture of the brick itself: FIGURE 12.17 Cleaning out the extra types FIGURE 12.18 Editing the boundary of the filled region FIGURE 12.19 Adding a texture to the brick family FIGURE 12.20 Changing the background to Transparent FIGURE 12.21 The finished soldier Now it’s time to add a mortar joint to the bottom of the brick. You simply add drafting lines: FIGURE 12.22 Adding the mortar joint The next step is to add shading underneath the brick pattern. To do this, you’ll create an entirely new filled region and add it to the brick by tracing over the existing filled region: FIGURE 12.23 Click the Filled Region button on the Detail panel. FIGURE 12.24 Changing the region to Solid Fill – Black FIGURE 12.25 Select the Solid Fill pattern, and click OK. FIGURE 12.26 Selecting the gray color (RGB 192-192-192) FIGURE 12.27 Press Tab to select the chain of lines, as shown here. FIGURE 12.28 The solid pattern covers the previous pattern. You’ll fix this in a moment. FIGURE 12.29 Sending the light shade to the back FIGURE 12.30 The finished brick FIGURE 12.31 The Load Into Project button FIGURE 12.32 The new soldier brick in the model The next group of procedures focuses on editing the bricks used in the repeating detail. You certainly want the same face texture, and it would be nice if there was a mortar joint between them. Before you modify the bricks, let’s explore how a repeating detail is created. The objective of the next procedure is to discover how a repeating detail works and how you can create a new one: FIGURE 12.33 Click the Edit Type button after selecting one of the brick repeating details. You can change the spacing and the patterns of how the repeating detail will perform. The next objective is to modify the specific detail component that the repeating detail is using. To do so, you must add an instance of the detail component (in this case, it’s Brick Standard : Running Section) and then edit the family. After you load it back into the model, the repeating detail will be up to date. If you would like to give it a shot and do it on your own, go ahead. If you would rather have some guidance, follow along: FIGURE 12.34 Place the Brick Standard : Running Section detail component off to the side. You’ll delete this occurrence of the component later. FIGURE 12.35 Draw the textured face while you’re in the Edit mode for the filled region. Draw the arcs for the mortar joint using lines. Compare your detail to the detail in Figure 12.36. FIGURE 12.36 The brick actually looks like brick! Next, you’ll anchor this façade back to the wall. Two things need to be added: a structural relief angle above the soldier course, and a brick tieback to a lower course. Follow along: FIGURE 12.37 Placing the L6X4X5/16 angle Of course, the line weight is basically a blob, so you must modify the family in order for it to look accurate. The next procedure is almost a review of what you had to do to the bricks: FIGURE 12.38 The angle in place and looking like an angle The next step is to find a fastener to anchor the angle back to the wall’s substrate. There is a problem, however. The type of bolt you need is a lag bolt that is power-driven from the exterior into the wall. Revit doesn’t provide one out of the box. Luckily, the book you bought does! To find the lag bolt provided with the book, go to the book’s web page, browse to Chapter 12, and find the file FIGURE 12.39 Inserting the lag bolt Next, you’ll add a corrugated wall tie to the brick below the soldier course. Because the brick is a pretty good distance away from the wall, you first need to add some wood blocking to the model: FIGURE 12.40 Adding the wood blocking The next step is to add the corrugated wall tie. You’ll do this in the same manner, except that it’s located in a different directory: FIGURE 12.41 Placing the corrugated wall tie Now you’ll add some blocking along the concrete parapet cap. You also need additional blocking along the lag bolts. If you would like, go ahead and copy the 2×6 blocking around the model to mimic the figure at the end of this series of steps. Or you can follow along: FIGURE 12.42 Rotating the blocking after copying it When you’re drafting over a true section of your model, it’s always good to try to use as much of the graphical information from the actual model as possible. For example, the 3/4˝ void you see the bolt going through is actually 3/4˝ plywood sheathing. For some reason, the default plywood material has its cut pattern set to None. Let’s fix this: FIGURE 12.43 Copy the blocking as shown. Now that you have a good grasp of adding detail components, you need to learn how to control the line weight so the outlines of the bricks look a little bolder. FIGURE 12.44 Show us your plywood! If you remember, some of the detail components were modified based on the line weight of the filled region perimeter. This thickness was changed from Heavy Lines to Detail Items. You need to set Detail Items to a thickness you can live with: FIGURE 12.45 Changing the Detail Items Projection line weight to 2
