Introduction

Revit is a building information modelling software that allows the user to create and design a 3D model building structure. It is an architectural, structural and mechanical software where the user can provide 3D illustartion of the building as well as its design

2.Detail procedure

1) Use the shortcut keys in Revit discussed in class to complete the following tasks and list them below
a. Using 3D model create a section box

Procedure:

• Shortcut for this action is "BX"
• First select the desired element for the command

• Then press the appropriate shortcut

• A box of the selected object will be created
• You can adjust the box by dragging the arrows shown at its sides

b. To create similar doors and windows in a floor plan layout

Procedure:

• SHortcut for this action is "CS"
• First select the desired element for the commanad

• Then press the appropriate shortcut

• A similar object will be created which can be placed at a desired location. This can be used for faster modeling of similar elements

• As shown, any selected singular element can be created using the command

c. To reduce the thickness of lines visible in plan views

Procedure:

• Shortcut for this action is "TL"
• Click on the software interface or the workspace itself
• Notice that the lines are thick

• Click the shortcut key and the lines will be thinner

• Do the same to bring the lines back to the original settings

d. To apply override settings to a floor in the model section view

Procedure:

• Shortcut for this action is "VG"
• To override settings for the floor, use VG and open the visibility/Graphic override

• Find the floor under the visibility tab

• Select the parametr you wish to override and change the floor settings as desired
• An example is when the patterns is overrided

• When the selected pattern is choosen, it will be reflected for the floor elements

e. To increase the range of visibility in a plan view

Proceduere:

• Shortcut for this action "VR"
• First click on the plan workspace

• Then press the appropriate shortcut
• The view range window appear

• use this to change allocation of your plan view

f. To select the previously selected items

Procedure:

• Shortcut for this action is "Ctrl+Left Arrow Key"
• It is used to reselect members when a mistake during this action is made

• Example is when the selected members are selected and you select another element without presing the Ctrl key

• Press the shortcut key to reslectt the previous members removing the current selected member

g. To add annotations to the model views

Procedure:

• Shortcut for this action is "DL"
• Use this to add dimension to your model

h. To bring the model elements in line

Procedure:

• Shortcut for this action is "AL"
• First select the desired location of alignment

• Then press element you want to align

• Example

i. To rotate the model elements

Procedure:

• Shortcut for this action is "RO"
• First select the desired element fot the command

• Then press the appropriate shortcut
• The rotation baseline will apear

• Click on the desired base point and select the desired angle of rotation

j. To move an object to another location

Procedure:

• Shortcut for this action is "MV"
• First select the desired element fot the command

• Then press the appropriate shortcut
• Select base point and move to desired location

k. To copy a model element

Procedure:

• Shortcut for this action is "CO"
• First select the desired element fot the command

• Then press the appropriate shortcut
• Select base point and Copy to desired location

l. To mirror an element about an axis

Procedure:

• Shortcut for this action is "MM"
• First select the desired element fot the command

• Then press the appropriate shortcut
• Select reference axis and the object will be mirrored

m. To create an array of model elements

Procedure:

• Shortcut for this action is "AR"
• First select the desired element fot the command

• Then press the appropriate shortcut
• Select base point the n pick the direction and distance

• Then decide the number of arrays. Say 5

• 5 Copies of the selected object will be made

2) Using Revit and the project used from week 6 to 8 prepare a schedule for the following

General: To create a schedule, use the schedule/Quantities tool under the view tab

• Select the element on the new schedule window

• Then select the parameters that will be included in the schedule under the schedule preoperties tab

• Click ok the n the schedule will be created
• The schedule created can be seen under the project browser tab

a. Walls

Procedure:

• The following parameters are used forthis schedule

WALL SCHEDULE:

b. Doors

Procedure:

• The following parameters are used forthis schedule

DOOR SCHEDULE:

c. Windows

Procedure:

• The following Parametrs are used for the schedule

WINDOW SCHEDULE:

d. Material – Concrete/Wood

Procedure:

• For this one the material take off tool is choosen

• Then select the desired element

• Now select the properties under the material takeoff properties

FLOOR MATERIAL SCHEDULE:

3) Using Revit Calculate area and volume of each room in the model with appropriate room tags applied to each room. Prepare a schedule report for area and volume of each room.

PROCEDURE:

• To create a schedule, use the schedule/Quantities tool under the view tab

• Select room as the element for a new schedule

• Provide the required parametrs for the schedule

• Click OK to create the schedule

4) Using the same schedule using the unit cost rate for materials available in the internet, prepare total cost of materials used in the project

• General: Columns can be inserted on the created schedules

• Use the steps above to create material takeoffs

• To add cost to the slected element, go to edit type and add in the cost of the material depending on the currency you are using

• Cost can also be added to the schedule by manipulating the table

• To create formulas, in the parametr window, choose calculated parametr designated by Fx symbol

• Create the desired formula

a. Total Cost of Materials

b. Individual Material Take off

WALL:

• Add cost of materials to be schedule

• Create materila takeoff list and add total cost of materials using a created

DOORS:

• Add cost of material to schedule

• Since doors are built in per piece, material take off will not be needed. Cost per piece will be provided in the schedule

WINDOWS

• Add cost of material to schedule

• Since WINDOWS are built in per piece, material take off will not be needed. Cost per piece will be provided in the schedule

FLOOR:

• Add cost of material to schedule
• Create material takeoff list and add total of materials using a created formula

5) Using the concept of Visual Programming discussed in class, list a flowchart for the following scenario
a. How to decide framings for a structure using Dynamo ?

Procedure:

b. If there is no water coming from the pipes

Procedure:

To determine soluntions for pipe problems, the following flowchart can be used

c. If request for money from client has been declined for the project

Procedure:

6) List the parameters associated with each model element

These parametrs are seen when the edit Type button is clicked when an element is selected

Sometimes, different parameters will be listed per family of as single element

a. Wall

A parameters associated with this element are:

---> System family: Basic Wall

---> System family: Curtain Wall
