1. BIM and its benifits over 2d cad tool

BIM is Building Information Modelling.
It is a concept created by Autodesk .
Rivet helps in achieving BIM as a process.

Features in BIM:

BIM is divided into 2 concepts:

a. Coordination :- Coordination is the key feature in BIM.

-Rivet helps in coordination of multiple disciplines.

- eg: Rivet offers in coordintion of projects in architecture, structural, mechanical etc. in single project as independent design theme units.

b. Computation:- Calculation of quantities of material , performing analysis

- To create material shedules, quantity shedule, perfoming energy analysis in Rivet

- In structural discipline in Rivet, robostructural analysis that helps in computing the response to the load applied in a building.

- Autodesk CFD,for computing floor and thermal computation in specification to mechanical engineering.

Rivet is a BIM tool that helps in achieving coordinating and computation as apart of model.

Benifits over 2D Cad tool :

Saving time:

-The modification of the model in one view will inturn reflect on all other view.

- Unlike 2d Cad tool , we do not have to edit the modification in the plan, elevation etc. , here in Rivet changes made in one view will be automatically loaded in all other views.

- If we select a wall in one view, the same wall in all other views will be selected and gets modified thus saving time.

- The changes will affect the quantities, computation also.

- It will also reflect in the paper space and model space.

2. Category , family and element

Category:

Categories are group of elements having common properties.
It is predefined by the software.
Eg: A wall or door, windows is an example of category.
We can insert element of our choice and create a category.
It controls the organization , visibility, graphical representation and sheduling options of the family within the project.

Family:

Family is different elements having same properties
Eg: Single flush door - It has different sizes having the same property
Family is a grouping of 2d or 3d information that serves to represent a discrete building or documentation element in the project.
It defines parametric, graphical and documentation requirements.

Element :

Element is the basic feauture which cannot be subdivided
Eg: In single flush door , the different sizes represent the element.
single fiush door of size 30"x80" , 30" x84" ,32"x84".
Element is a specific representation in a family defined by distinct parametric, graphical and documentation characteristics which make it unique from other types in the family.

Instance:

It is an individual representation of a type in the project defined by unique parametric ,graphical and documentation characteristics which make it unique from other instances in the project.

Eg:

Go to insert tab, click on load family
A Dialogue box appears, from that click on doors, which is the category
Another list of doors appears, double flush panel, double glass, double sliding these are families.
Click on door single panel
Then a dialogue box showing different sizes of doors appears , the different sizes represent elements.
30" x80" , 30"x84" ,32"x84" ,34"x80".
Select 30" x80" (element)and click ok , then the door gets loaded in the door properties in architectural tab.
Go to architectural tab, select doors (category) , go to single flush ( family) , and select 30"x80" ( element ) which is loaded .

Click on the 30" x80" size door and place it in a wall craeted , this is the instance.

3. Setting up a project

Aim : Setting up rivet softwate for a project:

- Creating template and setting units

- Saving the file

- Adding project information

- Creating backups

Procedure:

Step 1: Open the project file , select architectural imperial template imperial for units .
Step 2:To save the file : Go to file tab and click on save option and save the name as "Project 2".
Click on save.
Step 3:Go to manage tab ,click on project information tab
The project information dialogue box appears ,enter the organisation name, project details etc

Step 4: Setting backups:

Go to file menu , click on save as ,click on project .
Click on options in the save as dialogue box
File save option dialogue box appears , enter the no: of backups as 3
Click on OK and then click save.

Result: Rivet software is set for the project:

- Creating template

- Saving the file

- Adding project information

- Creating backups

4. Levels and Grids

Aim : To create levels and grids.

Levels:

- 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

Tools:

Level

Grid

Procedure:

Creating levels:

Step 1: Open a new project with imperial architectural template.
Step 2: Go to elevation - East in project browser
Step3: Already there are two levels by defualt.

Step 4:Level 1 at 0' and level 2 at 10'
Step 5:Rename the level 1 as ground floor by double clicking the level .
Step 6: Rename the level 2 as first floor -10'.
Step 7: To create new level, in architecture tab click on levels,clcik on pick line option and give the offset as 10' and then click on the first floor level.
Step 8: Level 3 is craeted at 20' from the ground floor
Step 9: Rename the level as second floor by double clicking the text of level.
Step 10: Similarly create the roof floor by offseting 10' from the second floor level.

Grids: Longitudinal gridsare drawn from right to left 1 to 10 and transverse grids from top to bottom A to E.

Step 1: Go to plan view, in the architecture tab, click on grid.
Step 2: Click on line and draw the grid line on the right side of the workspace.
Step 3: The grid number will be represented as 1 , if not double click and enter the value 1.

Step 4: Again in architecture tab , clickon grid and now select pick line and give the offset as 20' and click on grid 1.

, grid 2 is created.

Step 5: As the distance between the grid is 20' without moving out of command , click on grid 2 , thus grid 3 willbe created.

Step 6: Simlarly create 10 grid line with a spacing of 20'.

Step 7: In transverse direction , draw a grid by line tool and mark as A in top.

Step 8 : By pick line give an offset of 10' and pick the first grid

Step 9: As the distance between the grid is 10' , click on the B grid , then C will be craeted at distance of 10' without exiting from the command.

Step 10 : Similarly create upto E grid.

Result: Levels and grids are created.

5. 3d modelling of residential unit.

Step2: In manage tab go to project information , and add the informations

Step 3: Click on wall in architectural tab, in plan view draw the wall.
Step 4: Select height and draw the wall in level 1 .
Step 5:Change the level 2 to 3000mm if it is not.
Step 6: Draw the wall 200mm wall ,by clicking in the workspace .

Result: The layout of 3d residential unit is created.
