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

1.]

Ans. Building information modeling 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 :

- It is a physical representation of physical and functional characteristics of the building process,that provides every minute detail of the project

- One can easily access the right information at the right time that provides a reliable basis for decision making during a structure's entire life-cycle.

- 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,etc.

Benefits of using BIM over 2D CAD tools :

- Three dimensional building information modeling provides many advantages over 2D CAD due to vast capabilities of parametric modeling.

- All components modeled in 3D BIM software contain real world information about that component.

- If we place a wall within a BIM model,that wall would automatically include information about it such as its length,width,volume,weight,etc. with little to no additional input from the user.

Ans. 1] Categories :

In this there is classification of families,for ex: doors,curtain walls,furniture,lighting fixtures and so on.Families are grouped and sorted by category in the content libraries and in project browser.

2] Families :

A family is a group of elements with a common set of properties called parameters and a related graphical representation.Different belonging to a family may have different values for some or all their parameters but the set of parameters is the same.All the elements are families.Some families are included in model environment.Other families needs to be loaded into the model from an external library.

3] Elements :

Elements are the building blocks of a 3D model.they represent the real world components that a designer adds to the model.We can think of these elements as components that exist in a building.Other elements appear only in the views in which they are placed.

4] Instances :

Instances are individual graphical or geometric elements placed in a revit model.As a subset of revit elements,instances is a series of parameters from the category and type and might have instance parameters as well that only belongs to that single instance.The single element attached to the wall is door,that door we call as instance.

AIM - Setting up of a project in the revit software.

INTRODUCTION - For setting a project we need to select the architectural template for modeling the architectural plan.When we save the file with appropriate name,the name will be saved to the particular folder.The project units toolbar is used to set the project units,that applies to the whole project.The project information option is used to save the information of the project,by entering the project name,project issue date,project status,project address,etc.

PROCEDURE -

Step 1 : First select the file toolbar,then the new tab appears and select the new option and then select the project.

Step 2 : Next select the architectural template in the new project tab,then click OK.

Step 3 : After the project is done,open the file toolbar and select the save option.After selecting the save option the new tab will be visible.Enter the new name and before saving the name of the project,click the options at the right corner of the save as tab.Next we need to put maximum backups for project file to 3.

Step 4 : Next we need to select the project units in the manage toolbar.

Step 5 : 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.

Ans.

AIM - To create the grids and levels using the given details.

INTRODUCTION - Grid lines are finite planes,we can drag their extents in elevation views so that they do not intersect level lines.This allows you to determine whether grid lines appear in each new plan view that you create for a project.Grids can be straight lines,arcs or multi-segmented.we can hide grid lines after we add them.Use the grid tool to place column grid lines in the building design.We can then add columns along the column grid lines.

PROCEDURE -

Step 1 : For selecting the levels,first we select the levels in the project browser.

Step 2 : Next the levels will be displayed on the screen

Step 3 : Next we draw the grid lines horizontally,indicating the grids with A,B,C,D,E.

Step 4 : Next we draw the vertical grid lines on the horizontal grids,indicating the grids with numbers from 1 to 10.

Ans.

AIM - To create a conceptual layout of the residential unit in the revit.

INRODUCTION - Three dimensional models represent a physical body using a collection of points in 3D space,connected by various geometric entities such as triangles,lines,curved surfaces,etc.Being a collection of data,3D models can be created manually or by scanning.Their surfaces may be furthur defined with the texture mapping.

PROCEDURE -

Step 1 : First we have to draw the residential layout with the standard dimensions.

Step 2 : Next we change the visibility of layout as shaded.Next add the dimensions to the layout plan.

Step 3 : Next change the residential layout plan to the 3D view.

Ans.

AIM - To draft the level of details which include dimensions of room,components you plan to add in the residential unit.

INTRODUCTION - Dimensioning on a floor plan usually requires two or three continuous dimension lines to locate exterior walls,wall jogs,interior walls,windows,doors and other elements.Exterior walls of a building are dimensioned outside the floor plan.The outermost dimension line is the overall building dimension.The next dimension line,moving toward the plan,indicates wall locations and centerlines to doors and windows.

PROCEDURE -

Step 1 : From the previous residential unit drawn,we put the dimensions for the rooms.

Step 2 : Next we need to add the doors to the layout using the door option in the architecture toolbar.

Ans.

AIM - To insert the residential model elements such as doors,windowas,tables,chair,couch,bed,lamps from the library to the model.

INTRODUCTION - The residential model elements are door,windows,chair,bed,sofa.These elements are very important in the building model for construction.Comming to the 3D modeling in the revit,these elements are present in the library and we need to insert them into the model.

PROCEDURE -

Step 1 : We need to add the doors to the layout using the door option in the architecture toolbar.

Step 2 : Next we need to add the windows to the layout using the window option in the architecture toolbar.

Step 3 : Next we need to insert the dining table,kitchen stove and refrigerator in the kitchen.

Step 4 : Comming to the 2 bedrooms we insert the beds,chairs,furniture and table from the library.

Step 5 : Next comming to the toilet room,we insert urinals and shower from the library.

Step 6 : Next we insert furniture i.e; sofa into the hall from the library.

Step 7 : The all the model elements are inserted successfully and the layout plan is turned to the different views.
