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

Q1) What is BIM? Summarize the features of BIM and benefits of using BIM over 2D CAD tools

 

AIM: What is BIM? Summarize the features of BIM and benefits of using BIM over 2D CAD tools

 

ANS)

BIM is a Building Information and Modelling 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. 

  1) BIM is an acronym for building information modelling or management 

  2) it is a highly collaborative process that allows architext, engineersetc etc to plan, design and construct building within one 3D model

  3) This data allows govertments, municipalties and property managers to make informed decisions based on derivede from the model.

   

    Features of BIM are: 

• Easy access to information:                BIM is a physical representation of the phisical and functional characteristics of the building process, that provides every minute detail of the project 
• Making the process more expressive:  one can easily access the right information at the right time that provides a reliable basis for decision making during a structures entire lifecycle 
• Comprehensive view of the project:     BMI design tool allow you to obtain various views from a building and produced heigh quality accurate drawing  

     

       Benefits of BIM are: 

• Complete Representation: all component models in 3D BIM software contains real world information about that component 
• Instant Updates :             if you were to place a wall within a BMI model that wall would atomatically include information about it such at its length width within littel no additional input from this users 
• Time constraint:               requires less time compare to other softwars for drawing 3D 
• Resource tracking:            facility to location for current resourse tracking 

 

 

Q2) 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: 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

   

Procedure: 

     1) Categories: 

          a) classification of families,for ex, doors,curtain walls,furniture and electrical etc

          b) families are grouped and sorted by category in the content libraries and in the project browser 

   we got categories from load family option from components 

 

   

     2) Families: 

          a) A family is a group of element with a common set of properties,called parameters, and a related graphical representation.

          b) Diffrent elements belonging to a family may have diffrent value for some or all of their parameters, but the set of parameters is the same 

          c) all of the elements in revit are families 

   

     3) Elements: 

          a) Elements are the building block of a 3D model.

          b) they represnt the real-world component that a designer adds to the model  

          c) some elements such as wall, window, column and beam are 3d and present in all view 

          d) other elements such as tags,dimensions or ather annotation appears only in the view in which they are placed 

  

 

     4) Instances: 

          a) Intances are individual graphical/geometric element placed in revit model eg a single wall, or a single door, or any other single element

          b) as a subset of revit elements instance inherting a series of parameters from their category and type and might have instant parameter as well that only belongs to that single                            instants  

                       

 

 

 

Q3) 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

 

AIM: Setting up a Project in revit 2018

 

Introduction: for setting a project. we need to select the architectural templete for modelling the architectural plan 

                    when we save the file with appropriate name the name will be save in perticular folder 

                    then set the unit of sheet and fill all project information of project 

 

Procedure: 

 1) Open a Project with Architectural Templet 

    open the autodesk Revit 2018

    thats type of window are open on screen  

    

   then select architectural templet 

   so the project scape in architectural template are open on screen like that 

   

 

2) Save the file with appropiate name

   go to file toolbar located on left top on screen 

   then choose the save option 

   and give location where want to save 

   with name as ravit 2 challenge and press ok our file is save with same name 

  

 

3) Set up the project units to Imperial / Metric based on your convenience of modelling.

    go to unit command 

    press UN on screen OR go to manage tab and choose project unit option on screen 

    then choose a option where you change the unit 

 

  suppose we take length option 

  then we open the screen as mention below 

  in that we change the units as metric 

 

 

4) Complete the project information under Manage tab

   go to manage tab 

   choose a project information option 

  then click on that option 

  we tress out new window for inserting all information regarding project 

 fill all the inforamation like, organization name, organization Description, Building name, project issue date, project status and owner etc. and press ok

 

5) Set up the maximum backups for project file to 3

    go to file toolbar located top left corner of screen 

    then go for save as option in file toolbar 

    select on project option 

    then thats type of screen are opened 

 

 click on option tab situated below 

 set 3 as maximum for backup file 

 and press ok our file is backped 3 times 

 

 

Result: Setting up a project is done successfully in the revit in proper manner 

 

 

 

Q4) 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

 

AIM: creates a grid with given levels 

 

Introduction: Grids lines are finite planes, we can drag their extents in elevation views so that they do not intersect level lines 

 

Procedure: 

1) Set up the project units to Imperial 

    go to unit command 

    press UN on screen OR go to manage tab and choose project unit option on screen 

    then choose a option where you change the unit 

 

  suppose we take length option 

  then we open the screen as mention below 

  in that we change the units as metric 

 

 

2) create the levels 

   go to elavation view as east from project browser 

   then we show the screen like this 

   

  then go to structure tab then go on datum bar 

 and select the level option 

 then select pin from modify and set otion on 10'

 and set the two more levels on 10' to make four diffrent levels on 10' each 

 

3) rename the level

 rename the level by double click on level name 

 name it as ground,first,second and roof

 

4) Grids Transverse Grids A, B,C,D, E @ 10’ spacing Longitudinal Grids from 1 to 10 @ 20’ spacing

 go on architectural tab 

 and select grid option from datum 

 

then select line from modify for draw 

then again select grid option from architectural 

and select pick line from modify 

set offset as 10'

and draw or make 3 mode lines from last refrence line 

then rename the grid 

by double clincking on number 1,2,3,4,5 as A,B,C.D,E and press enter 

 

5) Longitudinal Grids from 1 to 10 @ 20’ spacing

go on architectural tab 

 and select grid option from datum 

 

then select line from modify for draw 

and draw longitudinal grid 

then again select grid option from architectural 

and select pick line from modify 

set offset as 20'

and draw or make10 more lines from last refrence line towards left right 

then rename the grid 

by double clincking on number as 1 to 10
