QTO BASIC
TUTORIAL
This Tutorial is copyrighted by Kevin R. Miller.
Modified 06-12-2012
OVERVIEW
QTO assists the estimator to quantify a project. By having the documents generated from BIM many
off the quantities can be obtained from the model and for items not modeled, measurements can be
taken on the computer monitor to generate the quantities that are needed. DWF or DWFx files are
needed for model takeoff; DWF,DWFx, PDF, TIF, GIF, JPG files can be used for Manual takeoff. QTO
doesn't takeoff directly from the Revit model files rather, QTO use the DWF(x)files which are
generated from Revit. The benefit of using the DWF files instead of the Revit model files are that the
file is read-only, the files sizes are much smaller than the original Revit model file, and the estimator
has copy of the model that doesn't change.
PROJECT SETUP
The Dataset for this tutorial is found on the Schedule page as the link 411 Data Files. This data file
needs to be downloaded and then extracted in order to be used with the instruction found in this
tutorial.
To start QTO, press the Start button , All Programs, Autodesk , Autodesk Quantity Takeoff 2013 ,
then select Autodesk Quantity Takeoff 2013 to start the application.

After the program opens, the Project Wizard window should be open (If the windown doesn't open, go
to the File pulldown menu and select New).
Name the project QTO??? and replace the question marks with your initals. The path for the project
should be F:\CM 411\QTO\, then press Next.
In the Specify Settings screen accept the defaults. Press Next .
In the Select Catalog window, press the down arrow and select Browse. Browse to F:\CM
411\QTO\Catalogs and select CSI-48QTO2011.att. Press Import . Press Next .
In the Import Files screen, press the Add button and browse to F:\CM 411\projects\dormitory
and select all the DWF files. Do NOT select the PNG file. Press the Import button. Then press the
Finish button.
On the Congratulations! window press Close .
On the Select Items To Import window, press OK .
The hard drive will spin for a minute or two and then a screen like this should appear.

If the Documents and Takeoff windows are not visible or docked on the left of the screen, go to the
Window pulldown menu and select the Documents and Takeoff options. If they are docked on the
left side of the window, select the tab and press the Thumbtack icon so it is pointing down (pinned)
instead of to the left . This will lock the window open so it remains visible.
ORGANIZATION
In the Takeoff window is a list of the 48 CSI codes. Many of the codes do not relate to the project that
is going to be taken off so we will delete some of the CSI codes below to make the list shorter (If the
codes would have been unselected from the Select Items To Import window that open as the last step
of the project creation, the codes also would not have been in the project). To delete the CSI codes
they first need to be unlocked. You will have less problems if you unlock all the groups at
once, press the padlock at the top of the column to unlock all the groups.

The divisions to delete are listed below.
Div. 00 - Procurement & reqs.
Div. 01 - General Requirements
Div. 13 - Special Construction
Div. 34 - Transportation thru Div. 48 - Electrical Power Gen
Now left click on the groups above and press the Del key on the keyboard, or right click and select
Delete.
In the Documents palette, rename the folders below. To rename the folders left click on the name,
wait a second and then left click again. An alternate method is to right click on the folder Rename. To
speed things up, you may want to copy the descriptions below and paste them into QTO.
Rename the following folders on the Documents palette:
QTO Dormitory Revit 3D DWF to 3D Model
QTO Dormitory Revit A100 Sheet to A100 Site Drawings
QTO Dormitory Revit A101 Sheet to A101 Arch Floor Plans
QTO Dormitory Revit A200 Sheet to A200 Arch Elevations
QTO Dormitory Revit A300 Sheet to A300 Sections
QTO Dormitory Revit A601 Sheet to A600 Reflected Ceiling Plans
Now from the QTO Dormitory Revit A103 Sheet folder drag the drawing (Sheet: A103 - Upper
Level 2 & Roof) to the A101 Arch Floor Plans folder, then delete the QTO Dormitory Revit A103
Sheet folder. To delete the folder, right click and select Delete . Repeat this process for the 2
remaining folders by dragging the sheets to the appropriate folder and then deleting the QTO folder.
Note: If all the drawings were contained in 1 DWF(x) file, there would have only been one folder
created and no need to drag and drop the images.
On the Takeoff palette groups and items need to be created so the takeoff can be organized. To
create a group named 09 22 16 Non-Structural Metal Framing, right click on the Div. 09 Finishes and
select New Group. Then type 09 22 16 into the WBS column and Non-Structural Metal Framing
in the description column. Repeat the process for the groups below. Hint: Right click and copy from
this tutorial and then paste the number into the WBS field and the name into the Description field.

09 20 00 Wall Assemblies
09 29 00 Gypsum Board
09 30 00 Tiling
Expand Division 08 Openings, it would probably be better to put the Metal Frames and Wood Doors as
groups under DOORS AND FRAMES. To do this, drag the Metal Frames group onto the DOORS AND
FRAMES group. This makes the Metal Frames a subgroup of DOORS AND FRAMES. Now drag Wood
Doors onto the DOORS AND FRAMES group.
Now summarize or collapse all the groups on the Takeoff palette so that only the major divisions are
visible.
PREPARING FOR TAKEOFF
The Takeoff palette is organizationally divided into Groups, Subgroups, Items and Objects. At the
Item level, Units of Measure can be defined and the objects that are taken off are displayed under the
Item level. Instructions on how to define the Unit of Measure is described below during the door
takeoff example below.
Prior to doing any takeoff, on the Documents palette, left click on Sheet: A101 - Entry Level &
Upper Level 1. Notice that all the lines are black with no other color in the plan area. The black lines
indicate that no takeoff has occurred. As the takeoff process moves forward, many of the black lines
will switch to various colored lines indicating that takeoff has occurred on those objects.
Navigational hint: To Zoom in and out, roll the mouse roller. To pan, press the mouse roller down
and hold it down, then drag to where you would like to go.

MODEL TAKEOFF
Model takeoff goes through the DWF(x) files and searchs for the objects in the model and create a list
of objects that were found.
To perform a takeoff of all the items found in the model, do the following 2 steps.
1. On the Documents palette open the 3D Model folder, select the QTO_Dormitory_2010.rvt. Now
the Model Takeoff Tool is available. Press the Model Takeoff tool (or from the Takeoff pulldown
menu select Model).
2. Now left click on the model (in the Canvas area) to perform the takeoff.
When the program is done creating a list of objects found in the model, a Model Takeoff window is
displayed. Press Close.

The figure at the right shows the Takeoff palette. The lower portion of the window shows where the
takeoff quantities are generated from the Model or by performing Manual takeoff. The upper portion of
the window is where the estimator organizes the takeoff quantities in a manner that can be used to
prepare and estimate. In a general sense, the lower portion of the window could be considered takeoff
quantities while the upper portion of the window could be considered estimate quantities.
PLEASE NOTE that the QTO_Dormitory_2010.rvt group inside of QTO is not the actual the Revit
model file. It is a copy of the Revit model that was generated in the DWF file.

The process of moving objects from the Takeoff Qty's section of the list to the Estimate Qty's portion
of the list, creates the opportunity for the estimator to organize the takeoff items according the
estimators view of the project and it also allow for changes in the estimate structure rather than being
"hard coded" to a specific organization structure.
After the model takeoff is complete, notice on the Takeoff palette that the last row is a group named
QTO_Dormitory_2010.rvt. The number in parathesis is the number of objects that were taken off
from the model. Also notice that in the 3D model, the colors have changed and the objects have
become transparent.

Press the black arrow next to the QTO_Dormitory_2010.rvt in the Takeoff palette. The takeoff
groups from the model are now displayed. Throughout the remainder of the tutorial, the doors,
elevators, walls, fire extishinquishers and ceramic tile will be taken off, illustrating various forms of
takeoff that are possible with QTO. There are additional forms of takeoff that can be done using QTO
that are not currently covered in this tutorial. To learn how to use the other forms of takeoff, go to the
help menu and review the getting started guide.
DOORS
Expand the Doors group (located in the Description column) that is under the
QTO_Dormitory_2010.rvt, expand the Single-Flush group, expand the 30" x 80" group. In this
group a Single-Flush [89861] takeoff object is visible. Notice in the Type column that it is
undefined. What undefined means is that the unit of measurement (UOM) for this object has not beendefined. To define the UOM right click on the 30" x 80" group, select Properties and change the
Type: to Count. There are other options that could be set, but for now click OK . Now right click on
the Single-Flush [89861] object and select Properties. Click on the Properties tab and expand
each area. Notice that nowhere does it state the material of the door. It could be wood, metal,
fiberglass etc. Press OK to close the properties window. When this door was created in the model, it
was created as a generic door therefore no material was identified.
For this tutorial we will say that the Single-Flush [89861] is a wood door. To include it in the takeoff
and place it in Div 08, left click the 30" x 80" Item (not the object) and drag it to 08 14 00 Wood
Doors on the Takeoff palette.
The 36" x 84" doors need to be included as well, so on the
Item make their Type be Count and drag them to the 08
14 00 Wood Doors group.
Under the 36" x 84" item, right click on the Single-Flush
[78958] object and select Views and then Sheet: A101 -
Entry Level & Upper Level 1. The door is now shown in
the Canvas area and should look something like the figure
to the right. Notice the red text that has been added, this helps you identify what has been taken off.
After many items have been taken off, the red text may become distracting. If you do not wish to see
the red text, from the View pulldown menu remove the check mark next to Labels.

The two different groups of doors will now be included in the estimate.
To make it easier to navigate on the Takeoff palette, collapse the Div. 08 - Openings group.
ELEVATOR
The next objects to be included in the takeoff are the elevators. On the takeoff palette expand the
Generic Models group and the i_Elevator-Center subgroup. In the group 80" x 51" ADA min.
notice that there are 6 elevator objects shown. Does this mean that there are 6 elevators or 1 elevator
with 6 stops or some combination in the middle? To determine this, right click the first elevator object
and examine the Views . Before you right click and select Views on the second elevator object, just
left click on the second elevator object. Notice that it is just to the right of the first elevator object.
Now Zoom out (roll the mouse wheel) to where the whole page is visible. Now left click on the third
elevator object. Notice that it is on the floor plan for the Level 2, but is in the same location at the
elevators on Level 1. Right click on the 5th elevator object and select views, zoom out to see the full
sheet and it becomes apparent that there are 2 elevators that serve 3 levels of the structure.
Therefore the information needed for the takeoff is that there are 2 - 3 stop elevators instead of 6
separate elevators. To accomodate this expand Div. 14 - Conveying equipment and right click on
14 20 00 ELEVATORS. Select New Item and change the description to 3 Stop Elevator. Set the
unit of measure in the Type column to Count . Now drag the first two elevator objects from the model
area of the Takeoff palette to the 3 Stop Elevator takeoff item.
The other 4 objects are not needed for the cost model so right click on the
QTO_Dormitory_2010.rvt group, select New Group, and in the WBS column type zNot Needed.
Now drag the i_Elevator-Center item group in the model to the zNot Needed. This will let others
know that these objects have been reviewed but are not needed for the cost model for the project.
Now collapse all the Elevator groups, by collapsing the groups it easier to navigate.
WALLS
The next items to be taken off are gypsum board and metal studs. The first thing that should be done
is to create the items for the 5/8" drywall and the 3 5/8" metal studs.
-
8/22/2019 Autocad QTO
11/15
Expand Div. 09 - Finishes so that the wall assemblies, metal studs group, and gypsum board groups
are visible.
Under the 09 22 16 Non-Structural Metal Framing group, right click and create an New item with
a description of3 5/8" Metal Studs and in the Type column of the Takeoff palette change the Type
ofCount, don't change the WBS column.
Under the 09 29 00 Gypsum Board group create an item with a description of5/8" Drywall and
the Type ofLinear.
The last item to create is under the Wall Assemblies group. Create an item with a description of10'
Tall 3 5/8" Studs 16 oc 1 Layer each side. Right click on the new Item and select Properties .
Change the Type to Linear. On the Assembly tab press the + button and browse to find 3 5/8"
Metal Studs and the 5/8" Drywall items that were just created. Hold down the CTRL key and left
click on both items, then press the Select button. Press the Apply button.
Now left
click on
the 5/8"
Drywall
row in the
Quantity 1 column. In the Quantity Values drop down box, select Length. Now type *, now from the
Quantity Values drop down box, select Height , and finally type * 2 . It should look like the image to
the right.
Now press the green Check Mark button.
Now click on the 3 5/8" Metal Studs row in the Quantity 1 column and from the Quantity Values
drop down box select
Length then enter * .75. This will count a stud every 16".
Click OK on the Takeoff Item Properties window.
Navigate to the QTO_Dormitory_2010.rvt, groups Walls, Basic Wall, Interior - 4 7/8" Partition
(1-hr), on the itemInterior - 4 7/8" Partition (1-hr) change the Type to Linear and the Length
-
8/22/2019 Autocad QTO
12/15
from Undefined to Length. Now drag the object Basic Wall [64072] to the 10' Tall 3 5/8" Studs
16 oc 1 Layer each side takeoff item that you just created. If the item 10' Tall 3 5/8" Studs 16
oc 1 Layer each side is collapsed, press the down arrow by the item.
Now right click on the object Basic Wall [64072] and select Properties. Notice that the length of the
wall is 16.00 feet. On the Height: row where is says Undefined , left click there and change it to
Unconnected Height. The value now changes to 10 ft. Press OK to close the window. By changing the
value from Undefined to Unconnected Height, QTO now knows and should remember that for height
you want to use the parameter of Unconnected Height from the Revit models.
If the Workbook palette is not visible, from the Window pulldown menu, select the Workbook. Press
the thumbtack on the Workbook palette should be pointing down so this window will remain visible.
Below the Model and the Workbook palettes will be covered.
Model Isolation
Various objects on the model can be isolated to ensure that you are selecting the right objects for the
takeoff. To isolate the Interior - 4 7/8" Partition (1-hr) wall objects, do the following:
Before you can isolate any object the 3D model must be visible on the canvas. If it is not, go to the
Documents palette and select the 3D model. The Model palette needs to be visible, if it is not visible
do the following. From the Windows pulldown menu, make sure there is a check mark next to Model.
If there is a check mark, the Model palette is docked at the left side of the screen. Select the Model
palette that is docked and then pin it open.
If you are running out of screen space you can adjust the palette widths and/or unpin the Takeoff
palette.
On the Model palette, expand the Walls and Basic Walls folders. Right click on the Interior - 4
7/8" Partition (1-hr) folder and select Hide others . Now from the model, only the 4 7/8" partitions
are visible. As you click on and off the object that was moved up to the wall assembly, you should
notice a color difference. This color difference helps you identify the objects that have been moved to
the estimate. (If there is not enough color difference, right click on the item wall assembly select
Properties and change the color to a color that will stand out.)

To show the entire model again, right click on any group or object on the Model palette and select
Show All .
Workbook
On the summary tab of the Workbook, expand the Div 09 -Finishes group until the 3 5/8" Metal
Studs and the 5/8" Drywall are visible. The quantities were generated by the takeoff item 10' Tall
3 5/8" Studs 16 oc that was just created. The 5/8 " Drywall area is 320 ft. To correct the unit,
double left click on the unit and change it to ft2. To check the calculation remember the length of the
wall was 16', and the height was 10' and there was a layer on each side of the wall.
Note: On the Workbook, the quantities are only shown for the sheet currently selected on the
Document palette. The numbers in parathesis on the Takeoff palette are for the entire project. If you
want the Workbook to show the quantities for the entire project rather than just the sheet press the
palette menu button , select Workbook Filter the select Project .
Now that you have check to quantities to make sure that it works as anticipated, drag all the 4 7/8"
partitions to the Wall Assemblies items. The reason that we didn't previously drag them was so you
could easily check the calculation.
MANUAL TAKOFF
On each floor outside the elevator doors, the designers forgot to include fire extinguishers. The fire
extinguishers can be included in the takeoff by performing a manual takeoff. First, select the floor plan
(A101) on the Documents palette then select the Count tool . Now on each floor plan (A101,
A103), left click somewhere in the area of the elevator doors. A
Takeoff Item Conflict window may open, just press Close in this window.
As you do this, at the top, or possibly the bottom, of the Takeoff palette, a Count item is automatically
created. Expand this takeoff item see the 3 objects. Drag the Count item under 10 44 16 Fire
-
8/22/2019 Autocad QTO
14/15
Extinguishers. Single left click on the Count item (not the 3 objects), wait a second and single left
click again, and rename the takeoff item to Fire Extinguishers.
IMAGE TAKEOFF
Not only can QTO perform takeoff from 3D models and 2D DWF files, but also takeoff can be
performed from image file formats (TIF, JPG, GIF and PNG) as well.
To import a PNG image file go to the File pulldown menu and select Import , select Sheets & Models.
Browse to F:\CM 411\projects\dormitory and select QTO Dormitory A101 Sheet.png. On the
Documents palette, a new folder called QTO Dormitory A101 Sheet is created. Drag the PNG file to
the A101 Arch Floor Plans folder. Delete the QTO Dormitory A101 Sheet folder.
Select the sheet QTO Dormitory A101 Sheet.png on the Documents palette. From this sheet
ceramic tile will be taken off in the 2 bathrooms on the Level 1 plan. Before the takeoff can occur, the
scale for the drawing needs to be set. Since there aren't any dimensions on the sheet, use the width
of the south entry door (Door 16) is 6' 0".
Select the Polyline Area Takeofftool to measure the area of the 2 bathrooms on Level 1.
A prompt then appears to set the scale. In the Drawing Units field, change the value to Feet.
The Sheet Scale: value should be Custom.
Now select the Set scale by plotting points... In the field Baseline Segment Length: enter 6 and
leave the unit field at Feet.
Now left click on the drawing at one side of the entryway, the left click again at the other side of the
entryway.
Press the OK button on the Set Scale by Plotting Points window.
Press OK in the Document Properties window.
On the Takeoff palette, go the 09 30 00 group. Create an New Item called Ceramic Tile. Change the
Type to Area. Now select the Area Takeoff tool to measure the area of the 2 bathrooms on Level
1. Double left click to close the area.
On the Workbook palette, goto the Div 09 - Finishes tab. Expand the groups to review the square
footage takeoff to ensure that the quantity makes sense. If the quantity isn't reasonable, set the scale
-
8/22/2019 Autocad QTO
15/15
again. (How should I know what is reasonable, you can always open the PNG file in OST, do a takeoff
there and see if it matches the takeoff from QTO).
To add points to the shapes, select the line or area that you want to add to, select the linear or area
takeoff tool, hold the control key and add points. (notice the plus sign by the cursor).
To delete points, do the procedure above, but hover over an existing point and the cursor will have a
minus by it and then you can delete a point from a manual area or linear takeoff.
EXPORTING DATA
It is important to be able to export the takeoff to another application like a spreadsheet or estimating
program. To export the entire takeoff, from the File pulldown menu select Export , then select
Quantities . From the Export Quantity Options window select All Sheets, then press OK . Save the file
to F:\CM 411\QTO.
Using Windows Explorer or My Computer, browse to F:\CM 411\QTO and double left click the XML
file. Internet Explorer should open with a File Download window. Press the Open button in the window
and Excel should open the file.
As you look around the spreadsheet, adjust the column widths to make them readable. Notice that
Labor, Material, Equipment costs could be placed on the objects in QTO. This was not done in the
tutorial because most companies will already have an estimating database created that would have
the costs for the takeoff. Therefore adding them into the QTO objects would be redundant work and
create more maintenance work to be done in QTO.
In Excel, save the file as an Excel Workbook to the F:\CM 411\QTO and then upload the file to
Moodle.
