REUSING DETAILS FROM OTHER REVIT PROJECTS |

Save the family with a unique name before loading it. Once it is loaded, you can quickly cyclethrough the various view detail options and see the power of using visibility settings in thefamily, as shown in Figure 22.20.

Imagine that the door has already been modeled and you are adding the lines representingthe swing. For that you add the symbolic lines in both plan and elevation to complete the element.When drawing new symbolic lines, use the Type Selector to dene the subcategory of the lines.

Reusing Details from Other Revit ProjectsThere are many times in a project workow when you want to leverage details already createdin other projects and reuse them. So far we have covered how to do this using CAD les fromother projects or from manufacturers’ websites. This workow is also possible using details cre-ated from other Revit projects. We will explain how to take an active project le and export key

details to the library. We’ll also discuss how to pull single details out of a Revit le and put theminto your active project.

Exporting Details from Revit ProjectsAs you create more and more details in Revit, you will inevitably want to save some of them toyour ofce’s standard library so you can reuse them in other projects and save the work you’veinvested. Saving a view out of a project creates a separate RVT le that contains only that view.There are a couple of ways to do this, either of which will result in the same outcome. First, ifyou have a 3D model detail that you’ve embellished with 2D components and would like to saveit for future projects, you can save it as a Revit le.

Right-click any view (or schedule) in the Project Browser and choose Save to New File. It mighttake Revit a minute to compile the view content, but you will be presented with a dialog box ask-ing you for a le location to save the view (Figure 22.21). The default lename will be the same asthe view name in the project.

Once the view is exported, it functions like any other RVT le. Opening the view directlywill allow you to edit and manipulate any of the elements you exported in the view. You willalso see a streamlined version of the Project Browser (Figure 22.22) with only the related viewspresent. These Revit les can be kept in a project library for later use.

REUSING DETAILS FROM OTHER REVIT PROJECTS |

Importing Views into Revit ProjectsTo import any of these les into a new project, switch to the Insert tab and from the ImportPanel and choose Insert from File Insert Views from File with the project open. This lets younavigate to your library containing your exported details. When you choose the exported detaille, a dialog box opens allowing you to select the view (Figure 22.24).

Notice that the view is described by both its location within the Project Browser (DraftingView) and its view name (Storefront Head Detail). Selecting this view and clicking OK mergesthe view into your current project. The view will appear in the location called out by the viewname. In this case, you can nd this view in the Project Browser under Drafting Views.

Another way to insert content into Revit is to use the 2D views from exported les. Forexample, elements of a detail you have in your library may need to be inserted into a view youare working on to augment that view. An excellent use case for this would be if you are creatinga new detail and want to reference or use parts of one from another project that is similar but

not exactly the same. An example of this might be a new detail of a window head in a concreteopening and you are reusing parts of a detail from a masonry opening. You may only want touse a selected portion of the new view in the current detail you are working on. To import the2D content into your view, follow these steps:

1. Open the view you want to import into, click the Insert tab and from the Import panelchoose Insert 2D Elements from File. The resulting dialog box looks similar to the one forimporting the full view but with some slight differences (Figure 22.25).

Unlike Insert Views, the Insert 2D Elements from File command allows you to choose only oneview at a time to insert. There is also an option to transfer the view scale with the view elements.Checking this box recongures the receiving view to match the view that you have inserted.

2. Select the drafting view and click OK. This brings all of the 2D elements in the selectedview into your active view. You can repeat this command multiple times in the sameview window if you need to repeat the content.

Using Detailing to Create a Shaft Opening

Revit offers a couple of ways to create an elevator shaft. One commonly used approach that we’veseen discussed on the community forums is to create a door family that also contains all the eleva-tor information (essentially, a combined door and elevator family in 3D). As a door family, it cutsa hole into a wall and gives proper representation of both the door and the elevator. This will give you your elevator, but then you need to perform a secondar y task of editing the oor slab prolesto accommodate the shafts. Although this method will work, it can cause a problem with makingsure the oor openings stay aligned between the oors. In our practice, we use a different method,which was used in creating the Foundation model. By using the Opening tool on the Modify tab,we can create a shaft opening.

Figure 22.25 Importing2D content.



THE BOTTOM LINE |

This tool allows you to create one vertical shaf t through multiple oors. This has a few benetsover the other method:

The openings in the oors will always be alignedu

We can extend this shaft through as many or as few oors as desiredu

The constraints of the shaft can be locked to reect the manufacturer’s required sizeu

Symbolic lines can be embedded in the opening to represent the elevator cab and can be drawnu

(or imported) to reect the manufacturer’s cab sizes and proportions

This last point is very valuable within our ofce. After creating the shaft, we can add the elevatorcab plan directly from the manufacturer’s CAD detail as symbolic lines.

Now, any time we cut the shaft in plan, it will display the elevator cab using these symbolic lines.If our building is complex in form and we need to move our view range up or down, we will alwaysmaintain the elevator cab in the plans.

The Bottom LineCreate 3D details. 3D axonometric details are a great way to demonstrate more complexassemblies and conditions in any document set. Knowing how to create them in Revit willexpand the ways in which you can detail.

Master It Use a 3D axonometric detail to demonstrate constructability in a unique as-sembly condition.

Add detail components to 3D families. Adding detail components to 3D families can savetime by embedding the linework of a detail within the family itself and making it instantlyavailable throughout all the locations that family is placed.

Master It Create a detail by embedding it into a family so it can be expressed by simplymodifying the detail level of a view.

Reuse details from other Revit projects. There are times when details are common between projects. Knowing how to use details from other Revit projects will cut down onyour documentation time.

Master It Use details you created in your other Revit projects.

Tracking Changes in Your Model

Once a project is under way in the construction document phase, changes to the design need to betracked. This is typically done on a per-sheet basis by adding revision clouds around elementsthat are changing in the drawings and documenting those changes in the title block of the sheet.The revision history of each sheet is then tracked in the title block with a number, description, andissue date. In this chapter we will look at adding new revisions, adding revision clouds to sheets,and assigning a cloud to a revision. We will also explore some best practice tips and tricks for per-forming revisions in Revit. Lastly, we will investigate using Autodesk Design Review to passcomments and markups back and forth between team members.

Adding Revisions to Your Project

Revisions allow designers and builders to track changes made to a set of construction docu-ments. Typically, these changes are recorded after a set of documents has been issued and per-mitted. Since the construction documents usually consist of numerous sheets, this methodologyallows everyone on the team to track and identify which changes were made by whom andwhen during the construction process those changes were made. The purpose is not only toensure correct construction but also to create as-built documentation at the end of the construc-tion process that can be delivered to owners for their continued use of the building.

In a typical workow, the revisions will look something like Figure 23.1 when they are cre-ated in Revit and issued as part of the drawing set.

To create a revision, open the Annotate tab and choose Revision Cloud from the Detail panel.This will put you in Sketch mode. Once you draw your revision cloud, open the Revisions dialog box found on the Manage tab in the Settings drop-down list. Here, you will see the default revi-sion, Sequence1, which is where your revision cloud has been placed. Here, you can also add,delete, merge, issue, and dene the behavior of revisions. Let’s go through the major elementsof this important dialog box.



674 | CHAPTER 23 TRACKING CHANGES IN YOUR MODEL

The numbering method You can choose to number revisions by Sheet or by Project. (ByProject is a global project setting.) Which method you should choose mainly will depend onhow your rm tracks revisions. By Sheet allows you to have as many revisions as you wantwithin the drawing set, but on each sheet, the revision numbers always start with 1. In theexample shown in Figure 23.2, the tags and revision schedule are unique for each sheet, depend-ing on what revisions are on each sheet. The revisions on each sheet are presented sequentially by sheet. This means you are chronologically numbering and tracking the changes that happenedon one particular sheet, not all the changes that happened in the entire project.

Using By Project will tag your revision clouds based on the global sequence establishedwithin the project as a whole. In this example, all revisions with the same issue date withinthe model would have the same revision number. So you might skip a revision number onany given sheet. You can also set up this numbering method in your default ofce templates.

ADDING REVISIONS TO YOUR PROJECT |

The revision table The Sheet Issues/Revisions dialog box starts with one default revisionalready in place, even though you may have not made a revision yourself. This is only so thatyou have a place to start. No revision will appear in your title blocks until you add revisionclouds to your sheet. Each revision has a xed number of parameters that you can ll out. Asyou can see in the dialog box, they are fairly self-explanatory and include numbering, date,

description, and an Issued check box, in addition to Issued To and Issued By columns andoptions for showing clouds and tags.

The Add button To create a new revision, click the Add button. The new revision willautomatically be placed in sequential order. Only the sequence number will be automaticallyupdated. You’ll need to add your own description and date.

Revision numbering The Numbering option allows you to number each revision numeri-cally, alphabetically, or not at all. If you choose alphabetic sequence, the sequence is denedin the Alphabetic Sequence Options, in the lower right of the dialog box. Click the Options button to set your sequence and remove letters you don’t want (Figure 23.3). By default, anentire alphabet will appear here. The None option will allow you to add project milestones—non-numbered entries that appear in revision tables—to sheets without having to add revi-

sion clouds.

Revisions To issue a revision, click the check box in the Issued column. This will lock therevision clouds placed on sheets or in views associated with that revision, preventing them

from being moved, deleted, or otherwise edited. The parameter values in the dialog box willgray out and become noneditable. This is to guarantee that the clouds and data do not changedownstream once you issue a set of drawings.

Revisions in a Live Model

Keep this in mind: while the clouds can become xed in the project, the model will not be. So, if youneed to maintain an archive of all project phases and of each revision, be sure to export the sheetseither as DWF or PDF les to preserve a snapshot of the sheets at time of issuance.

Revision clouds and tags The visibility of revision clouds and tags related to revisions thathave been issued is controlled from this dialog box. As issues occur, you may want to hideclouds or tags from previous revisions. This is where the Show parameter comes in handy.For example, if you’ve issued a revision and then add revisions later and want to clean upyour drawing, you can choose to show the issued revision as the tag only (typically a small

triangle with the revision number inside it, as in Figure 23.4) or not show anything at all, byusing the None option (Figure 23.5).

Merge Up or Merge Down If you need to combine two revisions into one, use the Merge Upor Merge Down button. All associated revisions on sheets and tags will update automatically.

Tracking Rev isions in the Title Block

The revision is typically a part of the architectural sheet and is located in a prominent position inthe title block to alert readers to changes made in the documents. These revisions can be incorpo-rated into your title block design so Revit will parametr ically read them from the sheet into a revi-sion table. To add a revision schedule to a title block, you will need to open the Family Editor andmake changes in the title block. Please refer to Chapter 4, “Setting Up Your Templates and OfceStandards,” to understand how that can be done.

Placing Revision CloudsTo place a revision, open a view in which changes to the model have occurred and use theRevision Cloud tool found in the Detail panel on the Annotate tab. Once you activate the tool,you will be dropped directly into Modify Revision Cloud Sketch mode. Start drawing linesaround the area you are calling out as a revision in a clockwise direction. Revit automatically

creates a line that makes a cloud (or series of arcs), as shown in Figure 23.6. When you’re nishedcreating the cloud, click Finish Sketch Cloud button at the top-right side of the Ribbon.

Like every other object in Revit, the graphics for revision clouds are controlled from theAnnotation Objects tab of the Object Styles dialog box, shown in Figure 23.7.

4. To check the export size, open the DWF Properties tab and click the Print Setup button.In the resulting dialog box, you can set explicit sizes for your export. Click the option UseSheet Size to let Revit autodetect sheet sizes based on the title blocks you are using in theproject (Figure 23.15).
