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.

Ans : Building Information Modeling is the foundation of digital transformation in the architecture, engineering, and construction (AEC) industry.A 3D model enables users to understand relationships between spaces, materials, and various systems within a physical structure. BIM software can be used for every step of the process, from planning to design to construction.

• BIM offers a more complete representation of a building's design. ...
• BIM pulls your documents into a single database.
• A BIM model will allow you to prefabricate important components ahead of time.
• You can provide much more to your clients using BIM than you could with CAD.

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.

Ans : Categories :Categories are an import tool within Revit for identifying the inferred type of an element, such as anything in the Walls category should be considered as a wall.

Families : it is a group of components used to build a model, for example, walls, windows, stairs, doors, bathrooms, fixtures, showers, etc., with a common set of properties, or parameters, and a related graphical representation.

Elements : Elements in Revit are also referred to as families. The family contains the geometric definition of the element and the parameters used by the element. Each instance of an element is defined and controlled by the family. Model elements represent the actual 3D geometry of the building.

Instances : An item from a catalog that is installed in your facility where the properties for that asset are unique to its installation.

Go to Insert Tab, choose a category. Pick a family and element. Understand the instances and insert it to Revit model : Revit-insert-Load families - inbuilt families will be available in autodesk

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

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

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.

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.

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
