Creating Levels, Grids, Layout and model elements for a residential unit using REVIT

#2 - Creating Levels, Grids, Layout and model elements for a residential unit using REVIT

1) What is BIM? Summarize the features of BIM and benefits of using BIM over 2D CAD tools.

Building Information Modeling(BIM):-

Building Information Modeling (BIM) is the foundation of digital transformation in the architecture, engineering, and construction (AEC) industry.

Building Information Modeling (BIM) is the holistic process of creating and managing information for a built asset. Based on an intelligent model and enabled by a cloud platform, BIM integrates structured, multi-disciplinary data to produce a digital representation of an asset across its lifecycle, from planning and design to construction and operations.

Features of BIM:-

Building Information Modelling (BIM)- Building information modeling (BIM) is a process supported by various tools, technologies and contracts involving the generation and management of digital representations of physical and functional characteristics of places. Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.

BIM allows you to bring all your designs, including CAD models, into a single database. Using the cloud, BIM provides access to this database to all project members. You’ll all work on the same models, which allows for quick changes as needed. When used correctly, BIM helps the entire team visualise the project. In fact, this is one of the main benefits of BIM in construction. The team can spot project issues before construction even starts.

That’s because of the sustainability aspect of BIM. The methodology allows you to design every aspect of a building. In addition to the building itself, BIM models feature electrical wiring and other important aspects of design. This creates a more realistic digital representation of the final product.

Advantages of BIM over 2D CAD Tools-

• BIM offers a more complete representation of a building’s design. It takes more than the building’s core components into account. For example, BIM allows you to design electrical and HVAC systems, as well as the building itself. This means the project team can take full advantage of the space and resources available.
• BIM pulls your documents into a single database. Several people can work on the same model and save it to the cloud. This allows for instant updates, so you won’t waste time searching for documents when you need to make changes.
• A BIM model will allow you to prefabricate important components ahead of time. You won’t have to adjust them based on the building design. Instead, such components are part of the initial design.
• You can provide much more to your clients using BIM than you could with CAD. The models you give to your clients update constantly as you work on your project. Your client can check in any time, which leads to quicker approval for milestones and more efficient project development.
• Resource tracking is a key component of BIM models. You’ll be able to figure out how much of each resource you need during the design stage. This improves the flow and efficiency of construction.

Both CAD and BIM processes are used to capture and communicate the design and construction intent of an AEC project using a drawing representation, helping stakeholders understand what needs to be built, and how. BIM enables design and construction teams to leverage their technology investment to do much more. The BIM process supports creation and management of information across the lifecycle of an AEC project by federating all multi-disciplinary design and construction documentation into a common dataset. Since that data can be accessed in multiple representations, from 2D to 3D to tables, the information is far more accessible and connected than the disparate data sources associated with traditional CAD approaches.

2) Understand the concept of Categories, Families, Elements, Instances in Revit. Go to Insert Tab, choose a category. Pick a family and element. Understand the instances and insert it to Revit model

First we need to understand the concept of the Categories, Families, Elements, Instances in Revit, we discuss on by one below.

• We select the Categories, Families, Elements, Instances by selecting the load family in the insert toolbar.

CATEGORIES:-

• Classification for families, for example doors, curtain walls, furniture, lighting fixtures, and so on.
• Families are grouped and sorted by category in the content libraries and in the Project Browser.

FAMILIES:-

• A family is a group of elements with a common set of properties, called parameters, and a related graphical representation.
• Different elements belonging to a family may have different values for some or all of their parameters, but the set of parameters (their names and meanings) is the same.
• All of the elements you use in Revit are families. Some families, such as walls or level datums, are included in the model environment. Other families, such as specific doors, or fixtures, need to be loaded into the model from an external library. You can't create anything in Revit without using a family.

ELEMENTS:-

• Elements are the building blocks of a 3D model.
• They represent the real-world components that a designer adds to the model.
• Some elements such as walls, windows, and beams are 3D and appear in all views.
• You can think of these elements as components that exist in a building.
• Other elements such as tags, dimensions, or other annotations appear only in the view in which they are placed.
• For example we select the family from the door catagory, after selecting the family the new tab will visible.
• Next there will be different sizes of door is there, select any one of them.
• Next that element is applied to the 3d model, and it will appears in the properties tab at the left side of the screen, as shown below.

3) Setting up a Project – Open a project file with architectural template. Save the file with appropriate name. Set up the project units to Imperial / Metric based on your convenience of modelling. Complete the project information under Manage tab. Set up the maximum backups for project file to 3

AIM:- Setting up a Project in the Revit software.

INTRODUCTION:-

• For setting a project. we need to select the architectural template for modeling the architectural plan.
• When we save the file with appropriate name, the name will be saved to the particular folder.
• The project units toolbar is used to set the project units, that applies to the whole project.
• The project information option is used to save the information of the project, by entering the project name, project issue date, project status, project address etc.

PROCEDURE:-

Step:-1

• First select the file tool bar, then the new tab appears and select the new option and then select the project.

Step:-2

• Next select the architectural template in the new project tab, then click ok.

Step:-3

• After the project is done, open the file toolbar and select the save option.
• After selecting the save option the new tab will visible.
• Enter the new name, and before saving the name of the project, click on the options at right corner of the save as tab, as shown below.
• Next we need put maximum backups for project file to 3.

Step:-4

• Next we need to select the project units in the manage tool bar.
• Next put the units to Feet and fractional inches, as shown below.

Step:-5

• Next we open the manage toolbar and then select the project information.
• After selecting the project information, the new tab will be visible, then enter the project details in the project information tab as shown below.

RESULT:-

• Setting up a project is done successfully in the revit in detailed manner.

4) Understand the concept of Levels and Grids. Follow the naming and conventions. Create the following Levels: ( Convert to metric equivalents if metric is your units)
Ground Floor @ 0’
First Floor @ 10’
Second Floor @ 20’
Roof @ 30’

Grids Transverse Grids A, B,C,D, E @ 10’ spacing
Longitudinal Grids from 1 to 10 @ 20’ spacing

AIM:- To create the grids and levels using the given details.

INTRODUCTION:-

• Grid lines are finite planes, We can drag their extents in elevation views so that they do not intersect level lines.
• This allows you to determine whether grid lines appear in each new plan view that you create for a project.
• Grids can be straight lines, arcs or multi-segmented. You can hide grid lines after you add them.
• Use the Grid tool to place column grid lines in the building design.
• We can then add columns along the column grid lines.
• As we start to construct our 3D model, we need some method of controlling the vertical height of our elements- be it floor heights, the base and top of columns, window cill heights, etc. This is where Levels come into play. In order to create an effective and efficient model, it is crucial that you understand the use of Levels. The correct use of Levels will ensure that your model can readily be adjusted with the minimum of effort.

PROCEDURE:-

Step:-1

• For creating the levels, first we select the levels in the project browse.

Step:-2

• Next the levels will be displayed on the screen, as shown below.

Step:-3

• Next we draw the grid lines horizantally, indicating the grids with A, B, C, D, E.

Step:-4

• Next we draw the vetical grid lines on the horizontal grids, indicating the grids with numbers from 1 to 10.

RESULT:-

• The levels and the grid lines are drawn successfully in the revit in detailed manner.

5) 3D modelling of residential unit – From looking at your house / or a place you aspire. Create a conceptual layout of the residential unit. You can measure using a tape or
you can access your residential plan to create a similar layout.

AIM:- To create a conceptual layout of the residential unit in the revit.

INTRODUCTION:-

• Three-dimensional (3D) models represent a Physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc.
• Being a collection of data, 3D models can be created manually, or by scanning.
• Their surfaces may be further defined with texture mapping.

PROCEDURE:-

Step:-1

• First we have to draw the residential layout with the standard dimensions, as shown in the below figure.

Step:-2

• Next we chage the visibility of layout as shaded, as shown in below figure.
• Next add dimensions to the layout plan, shown below.

Step:-3

• Next change the residential layout plan to the 3d view as shown below.

RESULT:-

• The conceptual layout of the residential unit is created successfully in the revit in detailed mannner.

6) In the layout created draft the level of details you are planning to include – Dimensions of room, components you plan to add in the residential unit.

AIM:- To draft the level of details which include dimensions of room, components to add in the residential unit.

INTRODUCTION:-

• Dimensioning on a floor plan usually requires two or three continuous dimension lines to locate exterior walls, wall jogs, interior walls, windows, doors, and other elements.
• Exterior walls of a building are dimensioned outside the floor plan. The outermost dimension line is the overall building dimension.
• The next dimension line, moving toward the plan, indicates wall locations and centerlines to doors and windows.
• Other miscellaneous details in the plan are located on a third dimension line.

PROCEDURE:-

Step:-1

• From the previous drawn residential unit, we put the dimensioins for the rooms, as shown below.

Step:-2

• Next we need to add the doors to the layout using the door option in the architecture toolbar.

Step:-3

• Next we need to add the windows to the layout using the window option in the architecture toolbar.

Step:-4

• Next we write the room name and its dimensions using the text tool, the text tool will be at the top of the screen, as shown below.

Step:-5

• Next we use the floor option to provide the floor for the residential unit, as shown below
• The floor option will be there in the architecture toolbar.

RESULT:-

• The level of details which include dimensions of room, components are successfully added in the residential unit.

7) Identify the residential model elements such as Door, Windows, Tables, Chair, Couch, Bed, Lamps from the library and insert them to the model . Save the project for use,for Assignment 3

AIM:- To insert the residential model elements such as Door, Windows, Tables, Chair, Couch, Bed, Lamps from the library to the model.
