When creating a project. Most often. Levels are infinite horizontal planes that act as a reference for level-hosted elements. By using a single project file. Having only one file to track also makes it easier to manage the project. Revit MEP elements are designed to be created and modified by you directly.
In Revit MEP. Revit MEP makes it easy for you to alter the design and have changes reflected in all associated areas plan views. Revit MEP classifies elements by categories. To place levels. In other cases. This implementation provides flexibility for designers. This information includes components used to design the model. Understanding the Concepts 9. Understanding the following terms is crucial to understanding the software.
The project file contains all information for the building design. A type can be a specific size of a family. They are not available for loading or creating as separate files.
Different elements in a family may have different values for some or all properties. A family groups elements with a common set of parameters properties. Read the following topics to familiarize yourself with the basic parts of the Revit interface. You can also display several project views at one time.
A type can also be a style. With a few clicks. Create an in-place family when your project needs unique geometry that you do not expect to reuse or geometry that must maintain one of more relationships to other project geometry.
You can determine the set of properties and the graphical representation of the family. Each family can have several types.
Families are classes of elements in a category. Then experiment with them. Unlike system and standard component families.
Its interface resembles those of other products for Windows featuring a ribbon that contains the tools used to complete tasks. In-place families are custom families that you create in the context of a project. There are 3 kinds of families: You can create multiple in-place families in your projects.
Instances are the actual items individual elements that are placed in the project and have specific locations in the design model instances or on a drawing sheet annotation instances. To return the panel to the ribbon. To minimize the ribbon 1 Click Show Full Ribbon to the right of the ribbon tabs.

Place a Wall. Zoom the view In the tutorials. The 3D isometric view displays: In the following steps. There are several ways to access zoom options.
Understanding how to adjust the view will make it easier to work with the MEP design in the window. The zoom menu lists the zoom options. The Navigation bar is located in the top-right corner of the view.
After you are familiar with these tasks. NOTE As you zoom in and out. To modify or add snap increments. The view of the MEP design is sized to fit the available window.
Revit MEP uses the largest snap increment that represents less than 2mm in the drawing area. Use the wheel mouse to zoom out to see the entire structure again.
In the drawing area. The cursor becomes a magnifying glass. If you do not have a wheel mouse. Modifying the View When you release the mouse button. SteeringWheels provide 2D and 3D navigation tools. Zoom is also available using SteeringWheels. Click and drag to orbit the design. The cursor displays a pivot point for the Zoom tool. Reorient the view You can use the View Cube in 3D views to spin the design or reorient the view 15 Place the mouse cursor over the South compass portion of the ViewCube to highlight the direction indicator.
You can change the pivot point by releasing the mouse button. To define settings for SteeringWheels. The Full Navigation wheel displays in the drawing area.
For more information about SteeringWheels. As you move the mouse. These are the drag controls. Performing Common Tasks In this exercise. Performing Common Tasks Small blue dots. Resize an element using drag controls 1 In the Project Browser. HVAC Plan. Similar controls. Notice the small blue dots that display at both ends of the duct. When drawing or modifying an MEP design. Selecting the second item in the list will undo the last 2 actions. All changes you make to a project are tracked. In this example.
The Undo command allows you to reverse the effects of one or more commands. All commands are canceled up to and including the selected command. NOTE To quickly undo the previous action. Move an element 7 Select the same duct used in the previous steps. Undo commands 5 On the Quick Access toolbar. Another way to move an element is to select it and drag it to a new location.
After selecting the element to move. Some commands. The duct is moved to the new position. End a command Some commands.
Override the display of objects You can control the visibility of objects in a view to display objects in specific ways.
Notice that the return air duct is not displayed. The template selection may vary depending on your installation. A project template enables you to start a project by providing initial conditions. You can either select a template from the template library. You can choose from several templates. You also learn how to use collaboration tools. You may need to have a variety of office templates if your work requires it.
In that case. New projects inherit all the families. You then learn how to customize the template by modifying the project settings and discipline settings. The first step in creating your office template is deciding which template to use as your starting point. When you select the material. On the Place tab. If you want to use a template other than the default. Modify project settings Project settings control the appearance of components and their subcomponents within a project.
To maintain office standards and reduce rework. Some templates are simple with respect to the predefined views and schedules.
For Building Construction. TIP This template is the starting point for your new template. Notice that construction template is more complex than the default template and the view properties have been modified to maximize the use of various tools. Discipline settings can be defined for electrical and mechanical disciplines. Mechanical settings determine the behavior and appearance of the ductwork and piping for mechanical.
Modify mechanical settings Revit MEP has discipline settings that define the appearance and behavior of the system components in a project. Define the tick marks that are used on wires by loading a family. After standard settings have been established for an organization.
Modify electrical settings Electrical settings determine the voltage. Duct sizes that are not commonly used are removed from the sizing lists to avoid having them created when sizing or laying out ducts.
Creating an MEP Project To enable this coordination. You need to create the MEP model for the project. You can customize the organization of project views and sheets in the Project Browser to group them into folders. Close coordination between the two models is essential because the building envelope changes will directly affect the MEP design. Linking Projects In this exercise. An architect has created a preliminary architectural model for a building project using Revit Architecture. Origin to Origin.
You can also set filters to determine the number of views and sheets that are displayed. You can use these techniques to create templates that are customized to your projects.
Notice that the file is saved as a template. The architectural model links to the MEP model and the current view remains active. Enable bounding elements for spaces 9 In the drawing area, select the linked architectural model. Adjust level lines You can adjust the level lines in the MEP design to match the level lines in the architectural model.
Monitor the architectural levels You can monitor the elements within a Revit MEP model, and when the monitored elements are not synchronized, warnings notify you of any violations.
These violations happen when the original monitored element from the linked project has changed, a copied monitored element in the host project has changed, or both original monitored and copied elements have changed.
Warnings may also appear when the original element in the linked file is deleted or the copied element in the host file is deleted. This establishes a relationship between the copied and original elements, which helps monitor changes to the original element and report differences.
After copying, appears above the copied elements, indicating that a relationship is established, and that the copied elements are monitored. If you modify a monitored element, a warning message displays, indicating that an element has changed. Creating and Applying a View Template In this exercise, you create a view template and apply it to your project template.
System settings are local to each computer and applied to all projects; they are not saved to project files or template files. These settings control the graphics, selection default options, notification preferences, journal cleanup options, and your username when using worksharing.
Set graphics settings 1 Click. Notice that the drawing area is black. When an error occurs, the elements causing the error display using this color. Notice the selected wall is yellow rather than the default red.
Notice that a tooltip is not displayed. However, the Status Bar displays information about the highlighted element. Specifying File Locations In this exercise, you specify default file locations.
These settings control locations of important Revit MEP files, including your default project template, family template files, and family libraries. Set file locations 1 Click.
TIP To view a template, you can start a new project with that template. Click and click Browse to select a template.
This path is set automatically during the installation process. These are the family templates that you use to create new families. It is unlikely that you would ever want to modify this path. However, there are some circumstances where you may need to modify the path, such as in a large, centralized, MEP firm where customized templates reside on a network drive. Specify library settings and create a new library 9 In the Options dialog, click Places.
The list is dependent on the options that you selected during installation. Each library path points Revit MEP to a folder of families or training files. You can modify the existing library names and path, and you can create new libraries.
When you are opening, saving, or loading a Revit MEP file, you can click on the library folder located in the left pane of the dialog.
In the following illustration, notice that the libraries display as icons in the left pane of the dialog. TIP You may want to create a new folder first. The library icons display in the order in which they are listed in the Options dialog. If you work in a large office. Specifying Spelling Options In this exercise. Notice that the spell checker allowed sheetmtl-Cu because you added it to the custom dictionary.
If you want to relocate this path. This path is determined during installation. Under Additional Render Appearance Paths. The custom dictionary opens in your default text editor. Notice that Revit MEP navigates directly to the library path. This path specifies the location of the Render Appearance Library.
Specifying Spelling Options Specify rendering settings 25 Click the Rendering tab.
Revit MEP uses the largest increment that represents less than 2mm in the drawing area. You can add an increment by entering the value with a semicolon after it. You can turn snap settings on and off. Notice that you can modify both length and angular snap increments. Modifying Snap Settings In this exercise. As you zoom in and out within a view.
This command resets the spelling settings to their original configuration. Snap settings are system settings that are applied to all projects and not saved within a project file. If you do not have a wheel button. If it does not. This dimension reacts to the movement of the cursor and numerical keyboard entries. TIP To zoom while sketching. Notice that when snapping is turned off completely. This is the increment that you added previously. While sketching. A listening dimension refers to the dimension that displays while you are sketching.
You can use these shortcut keys at any time when working on the design. Modifying Snap Settings Sketch without snapping 13 While sketching the wall. After you click to place the object at the midpoint. Make sure you also delete the semicolon. Notice that snapping is once again active.
If you move the cursor along the wall. This is the snap shortcut key that restricts all snapping to midpoints. Notice that the cursor snaps to various points on the wall. When you use shortcut keys to control snapping.
Do not set the wall end point. Creating a Mechanical System In this tutorial.
You also learn how to design a mechanical air system and a mechanical piping system. This information is used for heating and cooling loads analysis. After applying a color scheme to the zones. They contain information about the locations in which they are placed. This system consists of a cooling tower. Planning Mechanical Systems 4 In this tutorial. To create a mechanical system in Revit MEP. By following the recommended workflow. In this lesson.
Because most MEP engineers work with a linked model during system design. At the end of the tutorial. The goal of this tutorial is to teach you to design a mechanical system using Autodesk Revit MEP NOTE All exercises in this tutorial are designed to be completed sequentially. If the tutorial training files are not present.
This workflow begins with system planning and concludes with system designing. Then you assign zones to the spaces in order to control the spatial environment. This training file includes the work from the previous exercise s and ensures a seamless training session. Preparing Spaces Spaces allow you to calculate the volume of the areas in the building. After finishing each exercise. As you create the mechanical system. You can search this directory to verify that the training files have been downloaded.
In this section. This makes the architectural components such as walls. Add a Plenum level You create plenum levels so that you can place spaces in the unoccupied plenum areas between the ceiling and the floor above of the building. These components are defined in the architectural training file. Space Plan is highlighted. Configure the linked model for space bounding The most common method of designing systems in Revit MEP is to work within a linked architectural building model.
The linked model is configured to place spaces using the linked building geometry to define the space volume. NOTE When working with a linked file. You must place spaces in all areas occupied and unoccupied of the building to create an accurate analytical model and achieve an accurate heating and cooling loads analysis. The status bar located at the bottom of the window and the tooltip indicate the Linked Revit Model. A new plenum floor plan view named Level 2 Plenum is created.
Plenum from the Type Selector drop-down. Preparing Spaces The new level is placed. A black datum indicates a reference level the level is not taken into account during the creation of a view template. This creates only a floor plan after the level is added. Because you have not yet specified the view classification or sub-discipline properties. Apply a view template 19 Open the Level 2 Plenum view. Placing Spaces Spaces allow you to calculate the volume of the areas in the building.
The view graphics are modified based on the template applied. NOTE After finishing each exercise. Click OK twice. Notice that the site plan displays in the view. You apply the default view template so that only the architectural floor plan displays. In the next exercise. Modify plenum properties 17 In the Project Browser. Place a space 1 In the Project Browser. Tag Location. Placing Spaces You can also use the Highlight Boundaries feature to view boundary elements in the model.
This specifies the vertical extent of the space. Spaces can be created automatically and numbered in sequence by using the Create Automatically tool. The software automatically zooms the new view to the same location as in the open view.
Notice that the space number and name now match the room number and name from the linked architectural file. Notice that the space is created in the section view at the same time.
Place a space in the plenum 16 Click in the Level 2 Plenum floor plan to activate it. This is beneficial to split up large volumes for equipment selection and sizing.
Placing a Space in an Open Area In this exercise. Place a space in an open area 1 In the Project Browser. Placing a Space in an Open Area If you had modified the name and number in the schedule view instead. In the schedule. The new space is numbered correctly B. Notice the changed boundaries of the corridor space. Shading is a visual indication of where spaces have been placed shaded and where they need to be placed empty.
Placing a Multi-Level Space In this exercise. Add a multi-level space 1 In the Project Browser. Placing a Multi-Level Space Notice that you can see the space in the section view as well as in the plan view. You enter a value that is above the level of the roof. You have created a plenum level and a corresponding floor plan view. You used space separation lines to create a new fully bounded area that was part of a larger area.
Bounding elements such as walls. Space Plan. In the next exercises. Because the chase space is limited by a bounding element. All spaces in the view are tagged. Space shading and the space tags indicate spaces. The System Browser opens and docks to the right of the drawing area. The recommended workflow is to add each space to a zone that you create. NOTE A space cannot be placed into an area without being added to a zone. Zones allow you to control the spatial environment and to perform an accurate heating and cooling loads analysis.
After a space is placed in an area. The browser is a hierarchical list of spaces and the zones to which they have been assigned.
Revit MEP immediately adds them to the Default zone. Zoning is highlighted. Notice that Default is currently the only zone. Viewing Zones in the System Browser After spaces are placed in the building.
You can change the Occupiable parameter for each space. To display space reference lines. NOTE All space reference lines have been hidden in the training file to provide a clearer view of the floor plan. The different graphics in the System Browser indicate whether a space is occupiable unoccupiable or.
Viewing Zones in the System Browser The Zone tool is active. Assign spaces to a zone 1 In the Project Browser. Using the Edit Zone tab. The graphic in the System Browser updates. The new zone is listed in the System Browser. As you do this. You work with a single zone until you click Finish. Creating Zones on a Single Level In this exercise. Instruction In the System Browser. The zone reference line indicates that the 3 spaces are in the zone.
The new zone displays with color fill and a zone reference line. Creating Zones on a Single Level To view the zone in the drawing area. TIP After you finish editing the zone. The new zone name displays in the System Browser. You activated zone visibility in the views. Area B to confirm that the 3 spaces are in it. Area B. Rename the zone 7 Select the zone.
Creating Zones on Multiple Levels In this exercise. Create a zone for spaces on multiple levels 1 In the Project Browser. Zoning floor plan. Zoning view to activate it. Tag a zone 11 Activate the Level 1. Creating Zones on Multiple Levels Zoning view. Zoning to make it the active view. The tag only displays in the view where it was placed. Working with the Analytical Model In this exercise.
View a space 3 In the preview pane of the Heating and Cooling Loads dialog. You can expand the zone in the System Browser to view the spaces in it. Because the heating and cooling loads calculations have not been performed. Verify building information 1 In the Project Browser. Rename the zone 16 In the Level 1. The Isolate tool allows you to verify one or more spaces even if they are usually obstructed by other spaces or by the building architecture.
Right-click in the preview pane to access pan and zoom commands. The space for Lounge highlights in red. NOTE Wireframe displays the volume of a space measured by the interior boundaries. The space displays while all other spaces are hidden. Using the Highlight tool. Working with the Analytical Model You can also view a space in relation to the other spaces or architecture in the entire building. The Details tab contains a hierarchical list of spaces and the zones that have been assigned to them.
Below the list of spaces and zones. These specify the space usage and construction materials for the space.
All spaces in the zone display in isolation. This specifies the number of people or the area per person for the space. This specifies the lighting and power loads for the space. You can use the Space Type Settings dialog to adjust settings as necessary. Verify space information 7 On the Details tab. Revit MEP provides default settings for space types.
This indicates the cooling set point. This is usually preferable to indicating a particular percentage for those parameters. NOTE By not specifying values for the humidification set point and dehumidification set point. NOTE Shading displays the inner volume of a space. View the shaded model 11 On the View Selector. This indicates the outdoor air per person. The inner volume is bounded by interior surfaces of walls.
This indicates the heating set point. Modify space properties 19 Select the space. Because this is an unoccupied space. Add a space to fill a void 14 In the Heating and Cooling Loads dialog. Notice that Condition Type updates to Unconditioned. Add the plenum space to a zone 21 In the drawing area. Notice that there is a void in a second-floor plenum space. Analyzing Heating and Cooling Loads The report that is the result of this analysis allows you to determine the heating and cooling demands of the building.
Specify project settings 1 In the Project Browser. Analyzing Heating and Cooling Loads In this exercise. In order to select a space. Audio Visual. This is the parameter that determines whether a space is included in a heating load. NOTE The Areas and Volumes option must be selected in order to perform an accurate heating and cooling loads analysis. When the location is in an area that observes Daylight Savings Time. If you have made changes to settings in the Heating and Cooling Loads dialog.
Various factors such as analytical and inner volumes of the spaces are analyzed as Revit MEP performs the heating and cooling loads analysis. You can view the building materials for this construction type by clicking Building Construction dialog.
If a Warning displays for any space in the building. See Help for more information about the integrated heating and cooling loads analysis tool and its calculation methods. The information for the space that you entered in the Element Properties dialog displays.
Select the space associated with the warning. You have verified the building information. Revit MEP stores this information as project information. You should correct the space error in the building model. Perform a heating and cooling loads analysis 14 In the Heating and Cooling Loads dialog. There should be no warnings displayed. Zoning Load Fill is highlighted. You are taken to the place in the report where the space information is displayed for review.
Notice that the space information was automatically updated. Creating a Zone Color Scheme In this exercise. Assign a color scheme to a zone 1 In the Project Browser. After the heating and cooling loads analysis is completed. NOTE You must perform a new heating and cooling loads analysis each time you modify building. A color scheme allows you to communicate and identify parameters visually and spatially rather than by using space schedules or accessing element properties. You want a scheme that allows for a greater tonnage range.
Select a different color scheme legend 6 In the drawing area. The new scheme displays in the view. Notice that the cooling load is based on tonnage value. Creating a Zone Color Scheme The new scheme allows for a greater range of cooling load values. The colors are updated in the plan view to match the new scheme type.
Apply a color scheme to a section view 10 In the Project Browser. Space Fill is the active view. Specify schedule properties 4 In the Schedule Properties dialog: If you select Show categories from all disciplines. Define the schedule 1 In the Project Browser. Instead of placing this schedule on sheets as a construction document. You then use the schedule to adjust the air terminal airflow properties to more closely meet design requirements.
Creating an Airflow Schedule In this exercise. Creating an Airflow Schedule In the Schedule Properties dialog. Define the airflow delta formula 5 In the Calculated Value dialog: You format the Airflow Delta field to display as red when the difference between calculated and actual airflow is outside an acceptable range. On the Formatting tab: This concludes the planning stage of the systems project. Because no air terminals have been placed in the model.
In the next lesson. Under Conditions to Use. Double-click the column boundary to expand the column to the width of the text. In later exercises.
