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

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

AIM : To Summarize the features of BIM and benefits of using BIM over 2D CAD tools.

Procedure :

BIM is an acronym for Building Information Modeling or Building Information Management. It is a highly collaborative process that allows architects, engineers, real estate developers, contractors, manufacturers, 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 buildings using data that building or structure owners have access to (hence the Building Information Management). 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.

Objective :

BIM objects, the components that make up a BIM model, are intelligent, have geometry, and store data. If any element is changed, BIM software updates the model to reflect that change. This allows the model to remain consistent and coordinated throughout the entire process so that structural engineers, architects, MEP engineers, designers, project managers, and contractors can work in a more collaborative environment.

Following are some salient features of Building Information Modelling: BIM Modeling Services

• Easy access to information

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.

• Making the process more extensive

CAD software enable users to work accurately in 3 dimensions- length, breadth and depth.However, BIM Modeling service providers, are allowed to work in five dimensions, time and cost being the additional dimensions. They are thus able to produce accurate cost and material estimates and precise time schedules of the project even as the design is being developed.

• More comprehensive overview of the project

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.

• Lifelike views

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.

Advantages of BIM over 2D CAD Tools-

There are several BIM advantages, including the following:

• 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.

2Q.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.

AIM :To Understand the concept of Categories, Families, Elements, Instances in Revit. Go to Insert Tab, choose a category. Picking a family and element and  Understanding the instances and insert it to Revit model.

Procedure :

Category: A Category controls the organization, visibility, graphical representations, and scheduling options of Families within the Project.

Family:    A Family is a grouping of 2D and/or 3D information that serves to represent a discrete building or documentation element in the Project. It defines parametric, graphical, and documentation requirements.

Elements: Everything in Revit is an Element

Instance: An Instance is an individual representation of a Type in the Project defined by unique parametric, graphical, and documentation characteristics which makes it unique from other Instances in the Project.

Families are classified into distinct groupings of classes and sub-classes

• Elements: Everything in Revit is an Element.
• Classes: Elements are classified into a Model, Datum, or View-Specific class.
• Sub-classes: Model elements are further classified into Hosts & Components and, View-Specific are further classified into Annotations & Detail Items.

LOADING THE FAMILY FROM REVIT 2023-

• Open Revit 2021.
• Go to the insert tab.
• Select the option load families
• Select the particular family and enter in Revit.

INSERT TAB

 

LOAD FAMILY TAB

DOOR FAMILY

FAMILIES IN REVIT 2023

 Result : Families, Elements, Instances in Revit is successfully inserted in Revit software
