Creating Levels, Grids, Layout and model elements for a residential unit using REVIT
AIM:
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.
A). Building Information Modelling (BIM):-
- BIM is an acronym for Building Information Modelling or Building information Management.
- It is a highly collaborative process that allows architects, engineers, real estate developers, contractors, manufactures and other construction professionals to plan, design and construct a structure or building within one 3D model.
- It can also span into the operation and management of building using data that building or structure owners have access.
- This data allows governments, municipalities and property managers to make informed decisions based on information derived from the model even after the building is constructed.
Features of BIM:-
- BIM is a physical representation of the physical and functional characteristics of the building process that provides every minute detail of the project.
- Every stakeholder makes their discipline – specific input to make it a comprehensive shared information resource about the structure.
- One can easily access the right information at the right time that provides a reliable basis for decision making during a structure’s entire lifecycle.
- BIM models not only present 3D geometric view of the structure, they provide a more comprehensive overview of the entire building process.
- It covers every component of this process from geometrical aspect of the design to spatial relationships from light analysis to provision of various services from topographical information to quantities or properties of building components and so on.
- BIM design tools allow you to obtain various views from a building model and produce high quality, accurate drawings, These views are based on a single definition of each object and thus gives a more realistic and accurate idea of the final structure.
Benefits of using BIM over 2D CAD Tools:-
- Three-dimensional Building information Modelling (BIM) provides many advantages over 2D Cad due to the capabilities of parametric modelling.
- All components modeled in 3D BIM software contain real world information about that component.
- For instance, if you were to place a wall within a BIM model, that wall would automatically include information about it such as its length, width, volume, weight etc, with little to no additional input from the user, Because of this, once the 3D model is complete the information can quickly and easily be translated into schedules, drawings and much more.
2). Understand the concept of categories, families, Elements, instance in Revit. Go to insert tab, choose a category, pick a family and element understand the instance and insert it to Revit Model.
A). 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, Instance 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 grounded 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 same or all of their parameters, but the set of parameters 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 cant 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 windows, and beams are 3D & appear in all views.
- You can think of these elements as components that exists 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 category, 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 appear in the properties tab at the left side of the screen as shown below.


Instances:
- Instance are individual graphical/geometric elements placed in a Revit model EX; single wall or single door or any other single element.
- As a subset of Revit elements, instances inherit a series of parameters from their category and type * might have instance parameters as well that only belongs to that single instance.
- The single element attached to the wall is door, that door we call as instance 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 the project file to 3.
AIM:- Setting up a project in the Revit software
INTRODUCTION:
- Foe setting a project we need to select the architectural template for modelling 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, 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 & 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.

RESLUT:
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 level: ( Convert to metric equivalents if metric is your units)
Ground Floor @0’
First Floor @ 10’
Second Floor @ 20’
Roof @ 30’
Grids transverse 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 ceil height , 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 horizontally, indicating the grids with A,B,C,D,E.

Step:-4.
- Next we draw the vertical 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 Rsidential 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 models represents 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.

Step:-2.
- Next we change the visibility of layout as shaded, as shown in figure below.
- 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 manner.
6). In the layout created draft the level of details you are planning to include-Dimension of room, components you plan 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 & other elements.
- Exterior walls of building are dimensioned outside the floor plan, the outermost dimension line is the overall building dimension.
- The next dimension line, moving towards 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 dimensions 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 next 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.

Step:-6.
- Next the residential unit is changed to the three dimensional view, as shown below.

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
