Commercial Design Using Autodesk Revit 2021 Lesson 16 Introduction to Phasing and Worksharing: This chapter will start a small new exercise designed to explore two important features in Revit: Phasing and Worksharing. Unless a project is brand new, it will be using Revit's phasing feature. Additionally, if a project needs to be worked on by more than one person at a time, it will be utilizing Revit's Worksharing feature. Note: This tutorial can be done at any time separate from the rest of the book. Exercise 16-1: Introduction to Phasing Any project that involves remodeling or an addition should use the Phases feature in Revit. Revit is often referred to as three-dimensional modeling software. However, Revit's ability to manage elements over time is considered a fourth-dimension. This section will provide an introduction to Revit's phasing feature. The Phasing dialog (Figure 16-1.1) is accessible from the Manage tab.

There should never be a phase called "Demolition," as Revit handles this automatically (more on this later). Revit manages Phases with two simple sets of parameters: • Elements: • Views Phase Created Phase Demolished o Phase Phase Filter Among these four parameters, Revit is able to manage elements over time and control when to display them. Element Phase Properties As just mentioned, every model element in Revit has two phase-related parameters as shown for a selected wall in Figure 16- 1.2. The Phase Created parameter is automatically assigned when an element is created the setting matches the phase setting of the view the element is created in. Put another way, in a floor plan view with the Phase set to New Construction, all model elements created in that view will have their Phase Created parameter set to New Construction. The Phase Demolished parameter is never set automatically.

(104) (103) 16-2 Introduction to Phasing and Worksharing View Phase Properties Every view has two phase-related parameters, as shown for the floor plan view in Figure 16-1.3. Any elements added in this view would be designated as existing. The Phase parameter can be set to any Phase that exists in the project. This setting can be changed at any time; however, it is best to have one floor plan view for each phase-thus, the Phase setting is not typically changed. This setting represents the point in time the model is being viewed. TIP: Create existing and demolition views in a company/personal template.

CH To understand how the Phase Filter setting affects the view, look at Manage → Phasing → Phase Filters (See Figure 16-1.4). Elements will appear in one of three ways: • By Category • Overridden Not Displayed - Displayed as normal, no changes - -Modified based on Graphic Overrides tab settings - These elements are hidden Be careful not to confuse the Phase Filter column headings, New, Existing, Demolished and Temporary, as literal phases—they are not. Rather, they are a 'current condition' (aka Phase Status) based on a view's Phase setting and the element's Phase Created & Phase Demolished settings. For example, the 'current condition' of an Existing wall in an Existing view is considered New because the phases are the same. Think of it as if you are standing in the year 1980, looking at a wall built in 1980—it is a new wall. Similarly, a New Construction wall in a New Construction view is also considered New in terms of how the Phase Filters work (now all Existing walls are considered Existing). You are now standing in the year 2019 looking at a wall built in 1980. 16-3 Commercial Architecture Cad - 4... for each question, right?

Each condition will be explained in depth on the next pages. View Settings: Phase: Existing New Construction New Construction Phase Filter: Show Complete Show Previous + Demo Show Previous + New 16-4 now Introduction to Phasing and Worksharing Existing Conditions: When modeling an existing building, create a Level 1 - Existing plan view; do this for each level in the building. This view will have the following phase-related settings: Phase: • Phase Filter: Existing Show Complete Any model element created in this view will automatically have Phase Created set to Existing. Everything in the drawing to the right has the Phase Created set to Existing. FYI: One wall and both doors have their Phase Demolished set to New Construction-however, we cannot visually see that here. The Phase Status is actually considered New in this view. The phase of the element matches the phase of the view. Thus, because the Show Complete Phase Filter has New set to By Category, there are no overrides applied to this view. We see the normal lineweights and fill patterns. FIGURE 16-1.5 Existing view Demolition Conditions: When demolition is required, create a Level 1 - Demo plan view; do this for each level in the building. This view will have the following phase- related settings: Phase: New Construction • Phase Filter: Show Previous + Demo Often, new Revit users think it strange that the demo view needs to be set to New Construction given no new elements appear in this view. However, looking at the existing view just covered all existing elements (even ones set to be demolished) are considered "new." Therefore, the "time slider," if you will, needs to be moved past Existing to invoke the Phase Demolished setting. If this is still confusing, it should make more sense in the tutorial. 16-5 | FIGURE 16-1.6 Demolition view/n Question to answer: "how phasing and work-sharing can impact the design drafting process?"
