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

 AIM : 

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

 INTRODUCTION : 

LEVELS : 

• Levels are finite horizontal planes that act as a reference for level-hosted elements, such as roofs, floors, and ceilings. About Deleting Levels. When you delete a level, Revit also deletes associated views and model elements that are hosted by the level (for example: doors, furniture, and rooms).

GRIDS : 

• Grids are annotation elements that help organize your design. Video: Add Grid Lines. On the ribbon, click (Grid). Architecture tab Datum panel (Grid) Structure tab Datum panel (Grid)

MODEL ELEMENTS : 

• Hosts (or host elements) are generally built in place at the construction site. For example, walls and ceilings are hosts. Model components are all the other types of elements in the building model. For example, windows, doors, and cabinets are model components.

 

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

ANSWER:-

BIM:-

• BIM is a visual representation of the physical and functional characteristics of a facility from inception onwards .As such ,it serves as a shared information repository for collaboration throughout a facility's life cycle.
• BIM comprises of a suite of integrated technologies and processes that enable real time collaboration between the multiple project disciplines in an open cloud platform, thereby aiding in successful project delivery. REVIT is one of the tools that helps achieve BIM as a process.

 

Features of BIM:-

The main features of BIM are -

1. Coordination

2. Computation

3. Easy access to information

4. Making the process more expressive 

5. Comprehensive view of the project 

 

Benefits of using BIM over 2D CAD tools

1. Complete representaion 

2. Instant update

3. Time constraint

4. Resource tracking

 

 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:-

 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

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.

             

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.

Elements:

• Everything in Revit is an Element 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.

 

 DETAILED EXPLANATION:-

•  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 windows, 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.

 

INSTANCES:-

• Instances are individual graphical/geometric elements placed in a Revit model e.g. a single Wall, or a single Door, or any other single element.
  As a subset of Revit Elements, Instances inherit a series of Parameters from their Category and Type and might have instance parameters as well that only belongs to that single instance.
• The single element attatched to the wall is WINDOW, that window 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 project file to 3

PROCEDURE:-

• OPEN the Revit Application
• First , from the left corner, select the file tool bar, then the new tab appears and select the new option and then select the project.

 

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

 

• After the project templete creation  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.
• for that click on OPTION in the save as tab window as shown below;
• and then type the number of backups required

  

• Next we need to select the project units in the manage tool bar or simply type UN to involk it.
• Next put the units to Feet and inches, as shown below.

 

• 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

ANSWER:-

• For creating the levels, first we select the levels in the project browser
• the levels only sees in ELEVATION VIEW
• so we use elevation view as East view

• As, By default there are only two levels , we have add two more 
• we Named, LEVEL 1 AS GROUND LEVEL as shown below

• EAST VIEW- architectural- levels - give offset as 10' and pick line and draw the other lavels
• and renamed LEVEL 2 as first floor

• Renamed other levels also ,LEVEL 3 as second floor and LEVEL 4 as roof 

• Now , open the first floor view ,go to architectural tab, click on option grid and  draw a transverse grid as GRID 1
• Then,cliick on PICK LINES option on grid family , make offset as 10' and draw grids four times more 
• And renamed all grids as A,B,C,D,E from top to bottom order

• And again in the the first floor view ,go to architectural tab, click on option grid and draw  a longitudinal grid as GRID 1
• Then,cliick on PICK LINES option on grid family , make offset as 20' and draw grids four times more 
• And renamed all grids as 1,2,3,4,5,6,7,8,9,10  from RIGHT to LEFT order

RESULT:-

The levels and grid formations are as below;

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.

ANSWER:-

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

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

• Next we chage the visibility of layout as shaded, as shown in below figure.
• Next add dimensions to the layout plan, shown below.
• give floor to  the building by using floor option in the architectural tab
• pick floor architectural option , give the floor we wanted from properties window and pick any boundary maker tool like line or rectangle tpo draw a floor 

• 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 – Dimensions of room, components you plan to add in the residential unit.

ANSWER:-

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

• Next we need to add the doors to the layout using the door option 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

 

INTRODUCTION:-

• The residential model elements are door, windows, chair, couch, bed, lamps.
• These elements are very important in the building model for construction.
• Coming to the 3d modeling in the revit, these elements are present in the library and we need to insert them into the model.

    PROCEDURE:-

 

• take a project from previous asking question and all the further process on that plan 
• To the raw plan ,we need to add the doors to the layout using the door option in the architecture toolbar.

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

• THE BEDROOM with toilet room as shown, we insert the  bedrroom essentials and urinals from the library as shown in the below figure,

• Next we insert the furniture things in the hall from the library, as shown in the below figure.

• The residential model elements are inserted from the library, as shown below.

• The all model elements are inserted successfully and the layout plan is turned to the different views, as shown below.

  RESULT:-

• Residential model elements such as Door, Windows, Tables, Chair, Couch, Bed, Lamps are successfully inserted in the model from the library.
