Introduction

This introduction helps you get started with the Revit MEP 2009 tutorials and presents the fundamental concepts of the product, including:

■ how Revit MEP works.

■ the terms used when working with the product.

■ how to navigate the user interface.

■ how to perform some common tasks in the product.

Using the Tutorials

In this lesson, you learn how to use the Revit MEP tutorials, including where to find the training files and how to create a new Revit MEP project from a template file.

The Contents tab of the Revit MEP Tutorials window displays the available tutorial titles. Expand a title for a list of lessons in the tutorial. Expand a lesson title for a list of exercises in the lesson.

NOTE You may find it helpful to print a tutorial to make it easier to reference the instructions as you work in Revit MEP. The tutorials are also available in PDF format by clicking Help menu ➤ Documents on the Web in Revit MEP.

Accessing Training Files

Training files are Revit MEP projects, templates, and families that were created specifically for use with the tutorials. In this exercise, you learn where the training files are located, as well as how to open and save them.

Where are the training files located?

Training files, by default, are located in C:\Documents and Settings\All Users\Application

Data\Autodesk\RME 2009\Training. Training files are grouped into 3 folders within the training folder:

■ Common: generic files often used to teach a concept. These files are not dependent on imperial or metric units. Common file names have a c_ prefix.

1

(14)

■ Imperial: files for users working with imperial units. Imperial file names have an i_ prefix.

■ Metric: files for users working with metric units. Metric file names have an m_ prefix.

NOTE Depending on your installation, your training folder may be in a different location. Contact your CAD manager for more information.

IMPORTANT Content used in the tutorials, such as templates and families, is located and accessed in the training files location. Although this content may be installed in other locations on your system, all content used in the tutorials is included in the training files location to ensure that all audiences access the correct files.

What is a training file?

A training file is a Revit MEP project that defines a building information model and views of the model that are used to complete the steps in a tutorial. Many tutorials include a Training File section that references the training file to be used with the tutorial. In other tutorials, you create a project from a template, rather than opening an existing training file.

Open a training file

1 Click File menu ➤ Open.

2 In the left pane of the Open dialog, scroll down, and click the Training Files icon.

3 In the right pane, double-click Common, Imperial, or Metric, depending on the type of training file.

4 Click the training file name, and click Open. Save a training file

5 To save a training file with a new name, click File menu ➤ Save As.

In many cases, the work you do in a project during a tutorial exercise becomes the starting point for the next exercise. In many tutorials, you create a project or modify an existing project, save the changes, and use the saved version of the file to begin the next exercise or lesson.

6 Complete the information in the Save As dialog:

■ For Save in, select the folder in which to save the new file.

You can save the file in the appropriate Training Files folder or in another location. Note where you save the file so you can open it for additional exercises as required.

(15)

■ For File name, enter the new file name.

A good practice is to save the training file with a unique name after you have made changes. For example, if you open c_settings.rvt and make changes, you should save this file with a new name such as c_settings_modified.rvt.

■ For Files of type, verify that Project Files (*.rvt) is selected, and then click Save. Create a project from a template

7 To create a project from a template, rather than using an existing training file, click File menu ➤ New ➤ Project.

8 In the New Project dialog, under Create new, select Project.

9 Under Template file, verify the second option is selected, and click Browse.

10 In the left pane of the Choose Template dialog, click Training Files, and open Metric\Templates. 11 In the Choose Template dialog, review the Revit MEP templates.

Templates are available for specific building types: commercial, construction, and residential. Each template contains predefined settings and views appropriate for the corresponding building type. For most tutorial projects, you will use the default template, and customize the project as necessary.

12 Select DefaultMetric.rte, and click Open. 13 Click OK.

Understanding the Basics

In this lesson, you learn what Revit MEP is and how its parametric change engine benefits you and your work. You begin with the fundamental concepts on which Revit MEP is built. You learn the terminology, the hierarchy of elements, how to navigate the user interface, and how to perform some common tasks in the product.

What is Revit MEP 2009?

The Revit MEP platform for building information modelling is a design and documentation system that supports the design, drawings, and schedules required for a building project. Building information modelling (BIM) delivers information about project design, scope, quantities, and phases when you need it.

In the Revit MEP model, every drawing sheet, 2D and 3D view, and schedule is a presentation of information from the same underlying building model database. As you work in drawing and schedule views, Revit MEP collects information about the building project and coordinates this information across all other

representations of the project. The Revit MEP parametric change engine automatically coordinates changes made anywhere—in model views, drawing sheets, schedules, sections, and plans.

(16)

What is meant by parametric?

The term parametric refers to the relationships among all elements of the model that enable the coordination and change management that Revit MEP provides. These relationships are created either automatically by the software or by you as you work. In mathematics and mechanical CAD, the numbers or characteristics that define these kinds of relationships are called parameters; hence, the operation of the software is parametric. This capability delivers the fundamental coordination and productivity benefits of Revit MEP: Change anything at any time anywhere in the project, and Revit MEP coordinates that change through the entire project.

The following are examples of these element relationships:

■ The outside of a door frame is a fixed dimension on the hinge side from a perpendicular partition. If you move the partition, the door retains this relationship to the partition.

■ Windows or pilasters are spaced equally across a given elevation. If the length of the elevation is changed, the relationship of equal spacing is maintained. In this case, the parameter is not a number but a proportional characteristic.

■ The edge of a floor or roof is related to the exterior wall such that when the exterior wall is moved, the floor or roof remains connected. In this case, the parameter is one of association or connection.

How does Revit MEP 2009 keep things updated?

A fundamental characteristic of a building information modelling application is the ability to coordinate changes and maintain consistency at all times. You do not have to intervene to update drawings or links. When you change something, Revit MEP immediately determines what is affected by the change and reflects that change to any affected elements.

Revit MEP uses 2 key concepts that make it especially powerful and easy to use. The first is the capturing of relationships while the designer works. The second is its approach to propagating building changes. The result of these concepts is software that works like you do, without requiring entry of data that is unimportant to your design.

Element behavior in a parametric modeler

In projects, Revit MEP uses 3 types of elements:

■ Model elements represent the actual 3D geometry of the building. They display in relevant views of the model. For example, walls, windows, doors, and roofs are model elements.

■ Datum elements help to define project context. For example, grids, levels, and reference planes are datum elements.

■ View-specific elements display only in the views in which they are placed. They help to describe or document the model. For example, dimensions, tags, and 2D detail components are view-specific elements.

(17)

There are 2 types of model elements:

■ Hosts (or host elements) are generally built in place at the construction site. For example, walls and roofs are hosts.

■ Model components are all the other types of elements in the building model. For example, windows, doors, and cabinets are model components.

There are 2 types of view-specific elements:

■ Annotation elements are 2D components that document the model and maintain scale on paper. For example, dimensions, tags, and keynotes are annotation elements.

■ Details are 2D items that provide details about the building model in a particular view. Examples include detail lines, filled regions, and 2D detail components.

This implementation provides flexibility for designers. Revit MEP elements are designed to be created and modified by you directly; programming is not required. If you can draw, you can define new parametric elements in Revit MEP.

In Revit MEP, the elements determine their behavior largely from their context in the building. The context is determined by how you draw the component and the constraint relationships that are established with other components. Often, you do nothing to establish these relationships; they are implied by what you do and how you draw. In other cases, you can explicitly control them, by locking a dimension or aligning 2 walls, for example.

Understanding Revit MEP 2009 terms

Most of the terms used to identify objects in Revit MEP are common, industry-standard terms familiar to most architects. However, some terms are unique to Revit MEP. Understanding the following terms is crucial to understanding the software.

Project: In Revit MEP, the project is the single database of information for your design—the building information model. The project file contains all information for the building design, from geometry to construction data. This information includes components used to design the model, views of the project, and drawings of the design. By using a single project file, Revit MEP makes it easy for you to alter the design and have changes reflected in all associated areas (plan views, elevation views, section views, schedules, and so forth). Having only one file to track also makes it easier to manage the project.

Level: Levels are infinite horizontal planes that act as a reference for level-hosted elements, such as roofs, floors, and ceilings. Most often, you use levels to define a vertical height or story within a building. You

(18)

create a level for each known story or other needed reference of the building; for example, first floor, top of wall, or bottom of foundation. To place levels, you must be in a section or elevation view.

Level 2 work plane cutting through the 3D view with the corresponding floor plan next to it

Element: When creating a project, you add Revit MEP parametric building elements to the design. Revit MEP classifies elements by categories, families, and types.

Category: A category is a group of elements that you use to model or document a building design. For example, categories of model elements include walls and beams. Categories of annotation elements include tags and text notes.

Family: Families are classes of elements in a category. A family groups elements with a common set of parameters (properties), identical use, and similar graphical representation. Different elements in a family may have different values for some or all properties, but the set of properties—their names and meaning—is the same. For example, 6-panel colonial doors could be considered one family, although the doors that compose the family come in different sizes and materials.

Families are either component families or system families:

■ Component families can be loaded into a project and created from family templates. You can determine the set of properties and the graphical representation of the family.

(19)

■ System families include walls, dimensions, ceilings, roofs, floors, and levels. They are not available for loading or creating as separate files.

■ Revit MEP predefines the set of properties and the graphical representation of system families.

■ You can use the predefined types to generate new types that belong to this family within the project. For example, the behavior of a wall is predefined in the system. However, you can create different types of walls with different compositions.

■ System families can be transferred between projects.

Type: Each family can have several types. A type can be a specific size of a family, such as a A0 title block or a 910 x 2110 door. A type can also be a style, such as default aligned or default angular style for dimensions. Instance: Instances are the actual items (individual elements) that are placed in the project and have specific locations in the building (model instances) or on a drawing sheet (annotation instances).

Navigating the User Interface

One of the advantages of Revit MEP is its ease of use, specifically its clear user interface. The Revit MEP window is arranged to make navigation easy. Even the toolbar buttons are labeled, making it easy to understand what each button represents. Revit MEP uses standard Microsoft®_Windows®_{conventions. If}

you have used any other product that follows these conventions, learning Revit MEP is much easier. In the following illustration, the user interface is labeled. In the steps that follow, you navigate and become familiar with the user interface.

Express Workshop

The Express Workshop tutorials focus on specific areas of Revit MEP functionality and highlight powerful features that are integral to the most common MEP workflows. Each tutorial demonstrates tools you can use to complete tasks that are common to an overall workflow. When you have finished these tutorials, you will have a basic understanding of Revit MEP design and documentation tools, as well as some of the best practices that help you efficiently design and develop an MEP project.

Creating a Supply Air System

In this lesson, you create a supply air system that consists of 2 low pressure, secondary supply air systems and a primary, high pressure system.

In Revit MEP, an HVAC system is a logical connection between air terminals and HVAC mechanical equipment. After air terminals and mechanical equipment are placed in a model, you can create supply, return, and exhaust systems using these components. The systems are used to perform calculations and analysis, and to place and size ductwork, which is the physical representation of the system.

The model you use in this lesson contains the secondary system Mechanical Supply Air 1. To create Mechanical Supply Air 2, you place the variable air volume (VAV) box, connect it to existing air terminals, and size the ductwork. You then create the main trunk line for Mechanical Supply Air 3 and connect it to the 2 secondary systems. Finally, you add and connect the air handler, creating the primary supply system.

Creating a Secondary Supply Air System

In this exercise, you place a parallel, fan-powered, VAV box in the model. You then define a logical connection between the VAV box and 4 existing air terminals, creating a secondary supply system.
