Revit MEP View Templates

One of the advantages of Autodesk Revit is that each view has individual graphic, scale, discipline, phase and view range settings; and changes to these parameters only affect the selected view. The view visibility of categories and subcategories can be set and saved to a view template (similar to layer states in AutoCAD). Two examples of different views of the same level are shown below.

These view specific settings can also be a disadvantage when you have to use the same settings on another view. When you duplicate floor plans to create furniture, fire safety or area plans for different levels, you change different view settings for each type of plan. Instead of repeating the effort of changing each parameter every time you create these views, you can save them as View Templates. These can then be applied to other views. They can also be applied to new views as the default view template.

To create a View Template, set your desired view parameters, then from the View pull down menu, select Save As View Template. A dialog box will appear to let you apply a name to the view template. Additionally, you can set it by right mouse clicking (RMC) on the View name in Project Browser.

Note that Autodesk Revit 9 has slightly different terminology on the pull down and RMC menus. Instead of Save as View Template, it has the more descriptive, Create View Template from View.

You can also duplicate and rename existing View Templates from the Settings pull down by picking View Templates. All methods will bring up the View Templates dialog where you can review and change the parameters that you want applied to other views.

Within the Autodesk Revit Help is a list of the modifiable settings that can be saved to View Templates. However, it leaves out some of the parameters illustrated above that can also be set. Even though the crop region settings aren't shown in the View Templates dialog, I noticed that if the View Property Crop Region is checked on in both views, the crop region visibility state can be saved and set with a View Template.

The Autodesk Revit Help screenshot list of modifiable View Template Properties is shown below.

You can apply these saved view settings (View Templates) to other views by using the View pull down and selecting Apply View Template. This can also be done by RMC on the view name in the Project Browser and selecting Apply View Template. Multiple views can also be selected and set at once in the Project Browser.

Another way to apply a view template to multiple views is to RMC on a sheet and selecting Apply View templates to all Views. This will apply it to all the views that have been placed on the sheet.

The Apply View Template command opens up the Select View Template dialog where you will see all the View Templates that have been saved.

In the Select View Template dialog, you can also check a box to show Existing views, which will display existing views and also the view templates. Another option is to turn on All view types, which will show all view template types in the project. These existing views and view types can be used as a template to apply their view settings to other views. The third option is to Apply automatically to new views of the same type.

The View Template can also be applied through the Element Properties dialog for a view.

You may first use View Templates for plan views to control object visibility, lineweight and screening, but it is also useful for saving model graphic and shadow settings for 2D and 3D presentation views, as shown below.

Changes to the parameters in a View Template are not automatically applied to views that were assigned the View Template. There is no live link between them. If you change settings to the View Template, you need to reapply the modified template to those views it was set to originally. It will overwrite previous view property settings. The best location to change or create new View Templates based on others (duplicate) is by accessing View Template in the Settings pull down menu. You can also set parameters in a current view and save with the same name as an existing View Template. You will see a dialog stating that the template exists and asking if you want to replace (overwrite) it.

View Templates can be embedded in your Project Template and they can also be copied between projects by using Transfer Project Standards from the File pull down menu.

Deletion of view templates is only available in the View Options dialog. Deleting a View Template will not affect any existing views that it had been applied to previously.

Autodesk Revit 8.1 can only create and apply View Templates for geometric views. Autodesk Revit 9 allows View Templates for schedules as well, as shown below. The formatting of the schedule can be saved as a View Template and applied to single or multiple schedules at one time.

View Templates not only help standardize the look of construction document sets, but they also help you achieve it with less work.

Autodesk Updates Revit-Based Solutions for MEP Engineers

Autodesk has updated its Revit platform for building information modeling (BIM) software applications, and has expanded it's portfolio of solutions that address the building industry's evolving requirements for productivity and efficiency.

To even more closely align products with customer needs and requirements, Autodesk has modified the names of several Revit-based applications. Revit Architecture 2008 (formerly Revit Building), Revit Structure 2008 and Revit MEP 2008 (formerly Revit Systems) software products support new ways of working for architects, designers, drafters and engineers, helping them to predict, analyze and deliver better building performance.

Revit MEP 2008 delivers BIM for the mechanical, electrical and plumbing (MEP) engineering market with improved features to support building performance analysis and better decision making. Revit MEP 2008 is available as part of AutoCAD Revit MEP Suite, which combines Revit MEP 2008 for systems information modeling and AutoCAD MEP 2008 (formerly Autodesk Building Systems) for MEP documentation.

Important features in Revit MEP 2008 include:

• Fully parametric change management increases coordination and maximizes the efficiencies of the Revit-based workflows across the architecture and engineering teams.


• Automated exchange of engineering design information improves communication and minimizes design coordination errors between MEP engineering disciplines, as well as with the architectural and structural engineering disciplines.


• Integrated building performance analysis for sustainable design through a direct link to the Integrated Environmental Solutions (IES), Virtual Environment -- providing reportable building analysis data including annual energy requirements, whole building carbon emission output, occupant satisfaction, day-lighting and thermal analysis capabilities.


• Improved management of linked model information and improved DWF file specification support.


• Google Earth Plug-In for publishing Revit models to Google Earth mapping functionality.


• Better interoperability with Autodesk 3ds Max animation software to helpdrive design consensus across project stakeholders.


• Revit MEP 2008 also delivers new features to enable sustainable design with analysis of materials, quantities, energy use and lighting. With enhanced gbXML (Green Building Extensible Markup Language) functionality, designers can quickly perform energy analysis and study building performance using tools such as those from Green Building Studio, Inc. and IES Ltd.


• Construction documentation enhancements such as dependent views for split drawings, dimensions and element visibility.

Revit MEP Multi-Disciplinary Collaboration

Collaborating in an all-Revit environment will greatly improve the coordination of building components through its internal management of the project database. This tutorial provides some guidelines on how to undertake effective multi-disciplinary collaboration in Revit.

Collaboration Guidelines

Revit consists of three discipline-specific platforms: Revit Architecture, Revit Structure, and Revit MEP. Each team member must be working on the same platform version and product build to effectively collaborate. Revit is a forward compatible product. Therefore, the design team should know the current compatible platform versions.

The current compatible Revit platform versions are recommended below:

• Building 8, Structure 1 (MEP application was not developed at this time)
  
• Building 8.1, Structure 2 (MEP application was not developed at this time)
  
• Building 9, Structure 3, Systems 1
  
• Building 9.1, Structure 4, Systems 2
  
• Architecture 2008, Structure 2008, MEP 2008

It is recommended that product build numbers should match in each product. The product build can be located in each product's Help menu by clicking on About Revit… The same build should be issued to all team members in the same firm or errors could occur when trying to Save to Central when using Worksharing.

Collaborations Tools and Methods

The linking of each other's models using Revit's Copy/Monitor feature provides immediate visual feedback on what the other members are doing. The benefits include:

• The ability to see the each other's data in full context of the project
  
• The ability to graphically control the linked data to enhance how it is viewed.
  
• Support for Coordination Monitor and Interference Check.

The Coordination Monitor is the most intelligent tool for collaborating in Revit when utilized properly. The benefits include:

• The ability to choose components of the linked model to monitor for change.
  
• Multiple modes offer flexibility to Monitor and Copy/Monitor objects.
  
• With Copy/Monitor, elements from the linked model can be copied into the host project automatically creating a monitored relationship.

The Interference Check provides immediate feedback on component collisions. The benefits include:

• The ability to check interferences within a single project or linked models.
  
• The ability to check "On Demand."

Project Structure

Effective collaboration can be achieved in a single model environment. However, it is recommended that the models be separated from one another to gain full advantage of the collaboration tools provided in Revit.

Workflow Relationships

Each discipline creates a relationship based on their individual workflows:

• Architect/Structural Engineer: In this relationship, the structural engineer will leverage the architect's model using Coordination Monitor's Copy/Monitor mode to create copies of building components from the architect's model and to monitor it for change, as well as to establish a quick structural model of the project for their workflow. The architect can then use Interference Check to verify that architectural elements are not conflicting with structural components.
  
  
• Architect/MEP Engineer: In this relationship, the MEP engineer will link the architect's model to position components in context. The Coordination Monitor is used to leverage the architect's rooms and levels. Analysis parameters are added to the room elements. However, levels are necessary to copy/monitor rooms. The architect simply links the MEP model to show system elements in context to architectural elements.
  
  
• Structural Engineer/MEP Engineer: In this relationship, both parties benefit from interference detection to avoid collisions between structural and systems elements.

Based on these recommendations, the diagram below represents a suggested use of Revit's collaboration tools between each program/discipline.

1. The Architect will link in the Structural model and utilize Interference Check.
   
2. The Structural Engineer will link in the Architectural model and utilize Coordination Monitor.
   
3. The Architect will link in the MEP model and utilize Linked Models.
   
4. The MEP Engineer will link in the Architectural model and utilize Coordination Monitor.
   
5. The Structural Engineer will link in the MEP model and utilize Interference Check.
   
6. The MEP Engineer will link in the Structural model and utilize Interference Check.

Here are some overall guidelines on workflow procedures to keep in mind:

1. Use the Coordination Monitor only when necessary. Overuse of the Coordination Monitor could slow the linked model's performance. Some relationships need only be set up as a monitor, not a copy/monitor.
2. When Worksharing is invoked, be sure to follow these recommendations:

• Coordination Monitor should be set up to Central File if both files exist on the same LAN. All updates should occur when the Local Files are not being used.

• Open the project and Detach from the Central File when distributing the model to other consultants. The detached model should then be attached to the consultant's Central File.

Stage 1 - Leveraging Models

Architect to Structural Engineer

1. The Architect will send the architectural model to the Structural Engineer.

2. The Structural Engineer opens the delivered model and reviews its elements.

• Levels: Do they make sense for use in the structural model? Do the bubbles vary from the company standard?
  
• Grids: Do the bubbles vary from the company standard?
  
• Columns: What type of columns are available? Are the columns continuous or split?
  
• Walls: Are there structural walls needed in this project? What kind of walls were used?
  
• Floors: What kind of floors were used?

3. The Structural Engineer starts a new project.

4. The architectural model is linked in. This is accomplished by File > Import/Link > Revit. Use the Origin to Origin positioning method if shared coordinates are not being utilized.

9. The MEP Engineer monitors or copy/monitors the levels first.

10. The Options tool will be accessed again to review and set the room options.

11. Several of the room's parameters can be copied from the architectural model.

12. The rooms can be copied by phase if necessary.

13. After setting these options, the rooms can be copied using the Copy Rooms tool on the Design Bar.

14. The MEP model will continue being developed.

Stage 2 - Monitoring Models

Structural Engineer to Architect

1. The Structural Engineer will send the structural model to the Architect.

2. The structural model is linked in. This is accomplished by File > Import/Link > Revit. Use the Origin to Origin positioning method if shared coordinates are not being utilized.

3. The Architect can run Interference Check at this point but might elect to monitor the levels and grids to access additional features of Coordination Monitor.

Stage 3 - Coordinating Changes

The Architect

1. If the architectural model changes, this will initiate a warning dialog from Revit.

2. The changes can be viewed by accessing Tools > Coordination Review > Select Link.

3. Coordination Review will open revealing the alert. As the host, the Architect can post a comment regarding this coordination issue.

4. The architectural model is saved and sent to the consulting engineers.

The Structural Engineer

1. The Structural Engineer will receive the new updated architectural model.

2. It should be saved in the location of the previous version.

3. The structural model will then be opened.

4. Revit will immediately alert the user of a Coordination Monitor issue.

5. The Structural Engineer will access Tools > Coordination Review > Select Link.

6. Coordination Review will open revealing the changes.

7. On the In a linked project tab, the Structural Engineer can review any comments made by the architect.

8. On the In host project tab, the Structural Engineer can initiate an action.

• Postpone / Do Nothing: Leaves the change to be addressed at a later time.
  
• Reject: There is a difference in the host file and its associated monitored element. The change made to the element in the host file is incorrect and the associated monitored element needs to be changed.
  
• Accept Difference: Accepts the change made to the element and updates the new relationship.
  
• Modify, Rename, Move: The command name changes based on the action. The change is propagated to the host project clearing the queue.

Stage 4 - Interference Checking

The Structural Engineer to the MEP Engineer

1. The MEP Engineer will receive the new updated structural model.

2. It should be saved in the location of the previous version.

3. The MEP model will then be opened.

4. The MEP Engineer will access Tools > Interference Check > Run Check.

5. In the Interference Check dialog, the user can choose objects from the current project and compare them to that of a linked project.

6. The Interference Report dialog will display all instances of conflict.

7. These items can be revealed in any available views by Revit. One by one, they can be addressed.

8. The report can be refreshed to see if the conflicts were resolved through Tools > Interference Check > Show Last Report.

9. The goal is the message below.

This process continues over and over. Each discipline can function as a united team to deliver the full conflict-free building information model.

Autodesk Partners With Integrated Environmental Solutions to Enable Building Performance Analysis on Revit Platform

Autodesk, Inc. announced that it is partnering with Integrated Environmental Solutions Ltd. (IES) to further enhance the Revit software platform for building information modeling (BIM) to support sustainable design. At the 2007 AHR Expo, Autodesk will demonstrate a prototype of how the IES building performance analysis tools might be used in combination with Autodesk Revit Systems to generate accurate building performance analysis data. Such data can improve the decision-making process and empower architects and engineers to design better-performing sustainable buildings.

"The design of more sustainable and energy efficient buildings is key to mitigating the impact of climate change and to decreasing building operation costs. A critical part of Autodesk's further development of building information modeling is to expand the ability for our customers to conduct multiple types of analyses on their building information model," said Jay Bhatt, vice president, Autodesk Building Solutions. "Building performance analysis will help architects and engineers design more sustainable buildings and we're excited to partner with Integrated Environmental Solutions to bring these capabilities to the Revit platform."

A growing number of architects, designers and engineers are turning to the Autodesk Revit platform for BIM to meet these challenges. Through the combination of the Revit platform with building performance analysis tools that can examine the implications of alternative design strategies, take into account physical, climatic and environmental factors, and analyze energy use, lighting and materials in the Revit building information model, designers can help achieve higher operational efficiency and building performance.

Autodesk and IES are working together to provide robust building performance analysis capabilities to the Revit platform through a workflow between Autodesk Revit Systems, Autodesk's BIM design and documentation software for mechanical/electrical/plumbing (MEP) engineering, and the IES software suite. Through a demonstration at the AHR Expo, Autodesk and IES will display how these two software applications could be used in combination to conduct multiple building performance analyses including thermal analysis, load calculations, daylight assessment with LEED reporting and solar studies. These comprehensive analysis capabilities could help design teams better and more thoroughly understand the complex thermal, light and airflow inter-relationships within their design, allowing them to make more informed design decisions, minimize risk and optimize building performance.

Dr. Don McLean, CEO of IES Ltd. commented, "Through the support of building performance analysis tools such as those in the IES suite, we hope our partnership with Autodesk will help the industry meet the demands for sustainable design and increase the value of building information modeling."

Exporting Autodesk Building Systems Designs to Revit Systems

The first step in linking an Autodesk Building Systems MEP design to a Revit Systems project is to use the Export to AutoCAD functionality included within Building Systems. This feature saves all design data as AutoCAD entities (such as lines, circles, arcs, and blocks), which can then be read and understood by Revit Systems.

Creating a Design with both 2D and 3D Views

Autodesk Building Systems, through its use of intelligent objects, automatically creates 2D and 3D representations of the MEP designs which can be viewed by other AutoCAD-based applications, as well as Revit Structure. Use the following steps to create an Autodesk Building Systems drawing with both a 2D and 3D display for use in Revit Systems:

1. With the MEP design open in Building Systems, create a new layout and then two viewports.
2. In one of the viewports, set the view to Plan. Use the built-in display configurations of Building Systems to set the view to either 1-Line or 2-Line.
3. Set the second viewport to an Isometric view.
4. With the layout page still current, use the Export to AutoCAD feature.

Use the Export to AutoCAD feature in Autodesk Building Systems to export an MEP design for use in Revit Systems. Note the Export to AutoCAD feature exports all linework/objects in the Building Systems drawing, regardless where the linework/objects reside. Therefore, before using the Export to AutoCAD feature, detach the external reference of any structural floor plan. This will enable only the Building Systems data to be exported.

The exported file contains two block representations in model space; one in 2D and the other in 3D. These blocks represent the Display Configuration Views that were currently active in each viewport of the layout prior to export. Furthermore, each block representation is on its own layer (named for the layout viewport) as well. When linking this file into Revit, users can control the appearance of the floor plan and 3D views by working with the visibility of these layers. The exported file contains the 2D and 3D representation of the MEP design in model space.
