4) From the Annotate toolbar use the aligned option to add dimensions to the layout
Aim:
To annotate a drawing using aligned dimension
Introduction:
Annotation of a drawing is very important because it specifies the geometric details of the component. Annotating objects generally means showing geometric features like length, width, and height.
Procedure:
Open REVIT
Open the drawing created in question 3
Go to Annotate tab
Click on Aligned dimension
Select centre-to-centre points of two edges
Result:
5) Use the properties browser to switch to different wall types
Aim:
To change the wall type using properties browser
Introduction:
The wall type is based on the requirement and the design changes accordingly. Different wall types are present in wall families in the project browser of Revit, such as basic walls, curtain walls, and stacked walls. The wall type can be changed accordingly in properties.
Procedure:
Open REVIT
Open the drawing created in question 3
Select the previously drawn wall
Go to the property browser to change the wall type
Dropdown to see all the wall types
Click on the required type of wall to change the wall type

6) Create a 3D view from the view toolbar and save the view with the appropriate name
Aim:
To create a 3D view from the view toolbar and save the view with the appropriate name
Introduction:
The wall type is based on the requirement and the design changes accordingly. Different wall types are present in all families in the project browser of Revit, such as basic walls, curtain walls, and stacked walls. The wall type can be changed accordingly in properties.
Procedure:
Open REVIT
Open the drawing created in question 3
Go to the view tab
Click the 3D view in the create toolbar
Click on the default 3D view
Right-click on the view cube
Click save view
Result:
7) Navigate through the 3D model using the view cube. Orbit/pan through the model layout created
Aim:
To navigate through the 3D model using the view cube. Orbit/pan through the model layout created
Introduction:
Once a 3D model is created, we can navigate through the model using a view cube, which is changing to different views such as top, right, front, etc., and Isometric views.
Procedure:
Open REVIT
Open the drawing created in question 3
Open 3D view created in question 6
Click on view cube for different perspectives of the model viz, Top, Back, Right, Left, etc., or drag the mouse holding the left button to view the 360 view
Using the “Full navigation wheel” we can zoom, rewind, pan, and orbit the model
Result:
8) Use the visibility settings option below to switch models to shaded, realistic, hidden lines options
Aim:
To switch model view to shaded, realistic, and hidden lines options using visibility settings
Introduction:
Displaying objects in Revit in different ways, (visual styles) can help improve our workflow and help us understand our models better, and that is why we need to learn the ins and outs of each one of them so we can use them in the correct situations. Revit offers six default visual styles: wireframe, hidden line, shaded, consistent colours, realistic, and Raytrace.
Procedure:
Open REVIT
Open the drawing created in question 3
Open 3D view created in question 6
Go to the bottom toolbar and click on visual settings
Change the views as shown in the options
Result:
Wireframe view
Hidden line view
Shaded view
Consistent colours
Realistic
Raytrace view
9) Turn the sun path on and off to view shadings in the layout created
Aim:
To Turn the sun path on and off to view shadings in the layout created
Introduction:
Once a 3D model is created, we create a 2D wireframe model. Sun path decides the shadows and shadings of 3D views. Sun path is generally from east to west, so the time of the day and location affect the shadows formed. In Revit, we can give the location of the house and time to give an exact sun path to the view.
Procedure:
Open REVIT
Open the drawing created in question 3
Open 3D view created in question 6
Go to the bottom toolbar and click on sun settings
Set the location, preset, date and time
Turn on sun path at the bottom toolbar
Go to the toolbar at the bottom
Click on the shadows button next to the sun path setting to turn on the shadows from the sun settings
Result:
10) Use the Manage toolbar to enter project settings, project name, and project issue date (choose according to your convenience).
Aim:
To enter project settings, project name, and project issue date using the manage toolbar.
Procedure:
Open REVIT and Open Drawing
Open REVIT
Open the drawing created in question 3
Go to the Manage tab
Click on "Project Information" in the settings Tab
Fill in the details of the project
Result:
11) What is the Analyze toolbar used in Revit? How it is beneficial for design and modelling
Analyze tab consist of tools for detailed analysis of structure created/ layout created. An analytical model is created using this tab. Following are some components of analyzing tab:
- Analytical Model:
Adding boundary conditions, types of load such as point, line, and area loads, load cases, and load combinations of point, lines, and area conditions using this toolbar.
- Analytical Model Tools
It contains tools to adjust the analytical model, check for consistency, reset the model, and check member supports in this tab.
- Spaces & Jones
The toolbar is used to create space separators. Space separators are drawn to separate different rooms of the plan to differentiate the rooms. It also contains a tab to name the space that is separated.
- Reports& Schedules
Reports & schedules are prepared for the following:
- Heating and cooling loads report
- Duct Pressure Loss Report
- Pipe Pressure Loss Report
- Panel Schedules
- Schedule/Quantities
- Check Systems
Check systems for components such as duct, pipe, and circuits and show disconnects
- Colour Fill
- Energy Optimization
Energy Optimization for Revit is a fast, reliable, and scalable tool for better building energy performance.
- Analyze tab Energy Optimization panel
- Location
- Create Energy Model
- Generate
- Optimize
- Energy Settings
Energy Optimization for Revit provides clear guidance and direction towards better building energy performance for the entire design team, from concept to detail and design to the operation of new and existing buildings
- Route Analysis
Use route analysis to calculate the distance and time of travel from one point to another point in the model.
- Structural Analysis
Using this toolkit structural designers and engineers can optimize their workflows in the cloud and on the desktop by using the analytical model built in Revit software by extending the Revit model to Autodesk® Robot™ Structural Analysis Professional software, or supported third party analysis solutions. Once complete, analysis results can be easily stored and explored in the Revit environment.
12) What are the links that Revit supports to be linked to the model?
Following are the models Revit supports to be linked with the current model under production
- Link REVIT: Using this link two Revit models can be created i.e., one past and one current file. It specifies the relative locations of the individual buildings on campus or coordinates efforts across disciplines (Architectural, structural, and engineering).
- Link IFC: The Industry Foundation Classes (IFC) data model is intended to describe architecturally, building, and construction industry data. It is a platform-neutral, open file format specification that is not controlled by a single vendor or group of vendors. Link to an IFC file when one wants to perform additional design work in Revit using the IFC file as a reference.
- Link CAD: When we link a CAD file to a Revit model, Revit maintains a link to that file. Revit retrieves the current, saved version of the linked file and displays it in the model whenever we open the model. Any changes to the linked file are displayed in the model. If the linked file changes while the model is open, reload the file to retrieve the latest changes. This ability to retrieve the latest changes to a CAD file is the difference between linking and importing. When we import a CAD file, Revit uses the version of the file that has been imported. It does not retrieve or display changes to the imported file.
- Link Topography: When a civil engineer or a landscape architect creates topography data for a project and we want to reference it for a building model, we can link the topography to Revit.
- Link DWF Markups: When creating construction documents, a typical workflow is to print out a sheet, have it reviewed and marked up by the project architect or other professional, and then return it to the originator of the sheet to have the requested changes made.
- Link Decals: Use the Place Decal tool to place images on surfaces of a building model for rendering.
- Link Point Cloud: Link a Point Cloud file into the project to provide a highly accurate visual reference of the existing condition of a building or site.
13) Why do you need the Collaborate tab in Revit? How it supports modelling and its efficiency
Revit has been designed with collaboration that makes communication between disciplines understandable and easy.
- Revit Worksharing allows users to work on the same model remotely, which means that the users are constantly updated with the current edition, reducing the need for file transfers. The file management starts with the creation of a central model, which can be backed up to the cloud services.
- Revit offers colour coding tools that can automatically display the properties of spaces.
- The user can create Worksets, which are groups of elements in a model, allowing users to specify who can edit certain types of models. This helps to avoid inadvertent changes by other users in the same model.
- It also offers various Visibility and Graphics settings that allow the user to customize what they want to see and what they do not want to see
- It also defines Shared Parameters, which are saved separately from a project file to be used in multiple projects.
- Using Project Parameters can help all team members get organized by defining a parameter that categorizes views.
- Revit offers an Interference Check feature which allows the user to define which components to compare, and from which model the components are located.
Revit Cloud Work-sharing helps in modelling with efficiency
- As the Revit Cloud Work-sharing, the service helps to author Revit models in the cloud concurrently with other team members.
- Before Revit users collaborate on a model in the cloud, you must upload the model from Revit to BIM 360 Document Management. During the upload process, the following events occur:
- If the model does not yet have, work-sharing enabled, work-sharing is automatically enabled, the Revit model is uploaded to the BIM 360 project, and a locally cached version is created on the computer.
- If the model is already work shared, the Revit model is uploaded to the BIM 360 project, and a locally cached version is created on the computer.
- As alternatives to using Revit Cloud Work-sharing, one can use Revit Server to collaborate across a wide area network (WAN) or file-based work-sharing to collaborate across a local area network (LAN).
