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

 

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

  Answer :-

  BIM :-

• 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. 

  Features of BIM :-

   1) Coordination Feature :-

• The Revit as BIM tool helps in coordination between multiple disciplines.
• The different disciplines can come together and work on a single project as well as they have their independent design unit.
• They can coordinate in achieving progress in a project as a whole unit so the Revit offers this coordination which is a key feature in Building Information Modeling.

   2) Computation Feature :-

• The Revit as BIM tool helps in performing computation such as material schedule or quantity schedule or to evaluate the energy analysis. 

  Levels in BIM :-

• Different levels of BIM can be achieved for various types of projects.
• Each level represents a different set of criteria that demonstrates a particular level of 'maturity'.
• BIM levels start with 0 and go to 4D, 5D,and even 6D BIM.
• The purpose of these levels is to gauge how effectively or how much information is being shared and managed throughout the entire process.

1. Level 0 BIM : Paper-based drawings + zero collaboration.
2. Level 1 BIM : 2D construction drawings + some 3D modeling.
3. Level 2 BIM : Teams work in their own 3D models.
4. Level 3 BIM : Teams work with a shared 3D model.
5. Levels 4, 5 and 6 BIM : Adding in scheduling, cost,& sustainability information. 

  Difference between 2D CAD and BIM :-

• Basically, while using CAD for building design, user focus on creating drawings. But using BIM, user focus on creating a building model and then the drawings can be generated from the model. This saves time because you really do not have to draw anything twice.
• With CAD, user typically draw floor plans and then sections. But with BIM, you create the elements in one view and they appear in all views in which their visibility is turned on.
• Additionally, when it comes to documenting your design with tags and schedules, the parameters that are programmed into the elements can easily be used. This saves time when it comes to updating building components and it cuts down on errors since a component will not be tagged differently in two views.
• In BIM, the dimensions that comprise an object are interconnected. Therefore, any adjustment that needs to be made in a building design, such as the width of a wall or corridor can be done in a single edit.
• The great efficiency of using a BIM software means that the designer can concentrate more on the creativity aspects of a project without having to constantly worry about updating a multitude of line entities throughout the entire project. This translates into an incredible increase in productivity because each object, chosen from a BIM objects menu, already comes with a set of pre-defined information that can provide useful data for calculating project cost, thermal performance aspects, maintenance, structural,etc. It saves a lot of time. 

 

  Question 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.

  Answer :-

  Category :-

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

  Family :-

• A Family is a grouping of 20 and/or 30 information that serves to represent a discrete building or documentation element in the Project.
• It defines parametric, graphical and documentation requirements.

• There are three kinds of Revit Families :-

   A) System :-

• These are the families that are pre-defined families specific to a Revit Project.
• Their parametric, graphical and documentation requirements already exist.
• They can not be created in, deleted from,loaded into or saved out of the current project.

   B) Loadable :-

• These are the families that are user-defined families built in an editing mode called the Family Editor using family templates.
• Their parametric, graphical and documentation requirements can be defined from scratch.
• They can be created and loaded into a project as well as deleted or saved from a project.

   C) In-Place :-

• These are the families that are user-defined families created to represent a one-of-a-kind element unique to the project.
• Like System Families, they cannot be loaded into or saved out of a project but, they can be created within the context of the project using familiar Family Editor tools.

  Type :-

• A Type is a specific representation in a Family defined by distinct parametric, graphical and documentation characteristics which makes it unique from other Types in the Family. 

  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. 

  Creating Family in Revit :-

• Go to Insert Tab and click on "Load Family".

                                            

• From the pop-up box, Select Libraries.
• Select English > Structure Precast > Custom Slab.

                                          

• Select Hollow Core Slab and then click on "OK".
• Families can also be added from the "Project Browser".
