Performing Quantity Takeoff
33. Click the item name to enter editing mode, and then enter Dormitory Land Surface, and press ENTER 34 For Type, select Area.
35. Notice that the property in the Area column is Undefined. 36. In the Area column, select Surface Area.
All available Area properties are listed as values. Any property you select will yield a takeoff measurement.
37. On the Takeoff palette, drag the Dormitory Land Surface item to Building Site Surface. The item and its associated object are added to your project catalog and the Workbook.
38. Continue defining the Undefined items from the model takeoff, using the following table as a guide. Be sure to select an item type for each item. For item types other than Count, be sure to select a property whenever the item’s primary dimension is Undefined.
Note
Additional dimensions are defined automatically when the default properties are present in the objects. You need to define only one dimension to quantify an item, but you may define additional dimensions to generate secondary quantities.
Examples
Move this Undefined item: To this

39. Verify that the primary dimension for each item has a defined property. If you did not define a Length property for the Stair item when you moved it into the catalog, select a property, such as Actual Riser Height.
40. Rename items with more descriptive names, as needed. For example, under Furniture, rename 0457 x 0457 x 0610mm as Table-Night Stand 0457 x 0457 x 0610mm, and rename 1525 x 762mm as Desk 1525 x 762mm.
41. Click File menu Save.
42. On the Documents palette, select Floor Plans Sheet: A101 - Entry Level & Upper Level 1. Notice that the sheet icons in the Floor Plans folder now have takeoff indicators, and the Takeoff column shows the amount of takeoff data contained in each document.
43. On the canvas, notice that all of the objects you defined now display in their defined colors on the 2D sheet.
In a real-world project, you would finish defining takeoff data from the model takeoff results by moving the remaining Plumbing Fixtures and Rooms objects into your project catalog. In this guide, you quantify these objects using other takeoff tools to learn about the range of tools available in QTO.
Next, you use another automatic takeoff tool to create takeoff objects for the rooms in your project. Later, you use a manual tool to create takeoff objects for the remaining plumbing fixtures.
Using the Search Takeoff Tool
Using the Search Takeoff tool, you can quickly create takeoff for similar objects by using design data (dimensions and text) as search criteria. In this exercise, you use the Search Takeoff tool to find model objects with a Room property and create takeoff objects for them.
Note
Search Takeoff is run on the entire project. Select the takeoff geometry:
1. Verify that Sheet: A101 - Entry Level & Upper Level 1 is displayed on the canvas. 2. On the Takeoff palette, expand Building Areas Rooms, and select the Room item.
When you select a group or item on the Takeoff palette before starting the search takeoff, the takeoff objects are added to the selected group or item. If no group or item is selected, the objects are added to the root of the Takeoff palette.
3. On the toolbar, click (Zoom Rectangle), and zoom in to Room 5 at the upper left of the Entry Level.
4. On the toolbar, click (Search Takeoff).
5. On the canvas, move the cursor next to one of the walls inside Room 5 until the cursor changes from an arrow to a hand, and then click to select the room.
Specify the search criteria:
6. In the Search Takeoff dialog:
• For Name and Item Type, notice that the values cannot be modified. These values are inherited from the Room item you selected on the Takeoff palette.
• For Destination, notice that the location is determined by the item you selected.
If you browse to a different item, the Name and Item Type values are updated accordingly. • For Property, select Name in the Identity Data section.
The selections you make under Property are used as search criteria. • Click Search.
The takeoff objects are added to the Takeoff palette and the Workbook.
On the Takeoff palette, notice that the room objects inherit the Area item type from the Room item, and their primary dimension is mapped to the Area property automatically. Mapping this dimension allows QTO to quantify the objects.
7. In the Workbook, click the Building Areas tab, and expand Rooms. 8. Double-click the Room item to view room object data.
Because the Workbook is currently filtered to show data for the active sheet, only 16 of the room objects are shown. You can see the other 6 room objects by viewing the floor plan that contains the rooms. 9. On the Documents palette, select Sheet: A103 - Upper Level 2 & Roof to view the other 6 room objects in
the Workbook.
Alternatively, you can see all 22 room objects reported in the Workbook by switching from the Sheet filter to the Project filter.
10. Click (Workbook palette menu) Workbook Filter Project.
11. Click (Back) to return to the summary view.
By using the Search Takeoff tool to find model objects with a Room property, you have created takeoff for all of the living spaces. Using the same method, you can create takeoff for the bathrooms, conference room, lobby and corridor, mechanical rooms, and stairwells in your project.
12. Save the Dormitory project. Using the Single-Click Auto Takeoff Tool
Using the Single-Click Auto Takeoff tool, you can create a takeoff measurement with a single click on a piece of geometry in a 3D model or 2D sheet. By default, the takeoff data you create with this tool is grouped according to the family (or style) defined in the object’s properties. However, on the Contextual Tools palette, you have the option of grouping the takeoff data by selection instead. The grouping option you select becomes the default setting.
When you group by selection, the takeoff is added to the group or item that is selected on the Takeoff palette. If you add the takeoff to an item, the object(s) display below the item, using the name from the model properties. If you add the takeoff to a group, the object(s) are added to an Auto item within the group.
In this exercise, you create takeoff objects for lighted emergency exit signs in the stairwells. Modify the sheet display:
1. On the Documents palette, select Sheet: A101 - Entry Level & Upper Level 1. 2. Click View menu Fit to Window.
3. On the toolbar, click (Zoom Rectangle), and zoom in to the area around one of the stairwells. Create automatic takeoff objects:
4. On the Takeoff palette, select Electrical.
5. On the toolbar, click (Single-Click Auto Takeoff).
6. On the Contextual Tools palette, for Group by, select the Selection option.
Note: If the Contextual Tools palette is not displayed, click Window menu Contextual Tools.
When you group by selection, the takeoff objects you create are added to the takeoff group or item that is selected on the Takeoff palette.
7. On the canvas, click the room tags in all 4 stairwells on the Entry Level and Upper Level 1 floor plan. Drag the blue rectangle on the Navigator palette to navigate the floor plan.
8. On the Documents palette, select Sheet: A103 - Upper Level 2 & Roof.
9. Using the same method, create takeoff objects for the room tags in the stairwells on Upper Level 2. Verify that the Auto item is selected on the Takeoff palette before you click the room tags.
10. On the Takeoff palette, double-click the Auto item. 11. In the Takeoff Item Properties dialog:
• For Name, enter Emergency Exit Signs/Lights. • For Type, select Count.
• On the Cost Data tab, for Material Cost, enter 29, and accept the default multiplier. • For Labor Cost, enter 18, and accept the default multiplier.
• Click OK.
12. Expand the Emergency Exit Signs/Lights item, and rename each object with a descriptive name, such as Exit Sign - Emergency Light, Exit Sign - Emergency Light_2, and so on.
13. On the Takeoff palette, click the Filter list, and select View Defined.
This filter limits the takeoff data to only defined items and objects (and the takeoff groups that contain them). Now that you have defined the model takeoff data and added defined takeoff data for rooms and emergency exit signs, you no longer need to view Undefined items and objects.
14. Save the Dormitory project. Using Manual Takeoff Tools
Use manual takeoff tools to create takeoff for objects on 2D DWF sheets and non-DWF files, such as PDFs, DWGs, TIFs, GIFs, and JPGs. Manual takeoff tools count objects or measure drawing geometry, rather than using published design data as automatic takeoff tools do. This takeoff method is sometimes called on-screen takeoff.
In the following exercises, you create takeoff for toilets on all levels of the dormitory and for carpet in the corridor on the entry level.
Using the Count Takeoff Tool
The Count Takeoff tool tallies the occurrences of a particular object on a DWF or non-DWF floor plan and creates takeoff for each occurrence of the object. Use this tool to create takeoff for objects, such as windows and doors that have a Count Item type. In this exercise, you use the Count Takeoff tool to count toilets on a floor plan.
Modify the sheet display:
1. On the Documents palette, select Sheet: A101 - Entry Level & Upper Level 1. 2. Click View menu Fit to Window.
3. Click (Zoom Rectangle), and zoom in to the toilet next to the North Stair, at the upper right of the Entry Level.
Select objects to create takeoff:
4. On the Takeoff palette, under Plumbing Plumbing Fixtures, select Toilet - 480mm Seat Height. 5. On the toolbar, click (Count Takeoff).
6. On the Contextual Tools palette, for Symbol Size, select 4. 7. Select the toilet in Room 10, next to the North Stair.
Each time you select a toilet, a count symbol is placed on the sheet, and an object is recorded both on the Takeoff palette and in the Workbook.
8. Select the 3 remaining 480mm toilets on Sheet: A101 - Entry Level & Upper Level 1. Do not select the toilet in Room 15. It has a seat height of 380mm.
Drag the blue rectangle on the Navigator palette to navigate the floor plan. 9. On the Documents palette, select Sheet: A103 - Upper Level 2 & Roof.
10. Using the same method, select the 2 toilets on Upper Level 2. Be sure to select Toilet - 480mm Seat Height on the Takeoff palette before you select the toilets on the floor plan.
All 6 toilet objects are recorded both on the Takeoff palette and in the Workbook. 11. In the Workbook, click the Plumbing tab, and expand Plumbing Fixtures.
12. Double-click Toilet - 480mm Seat Height to view the object data.
When you performed the search takeoff exercise previously, you set the Workbook filter to Project view. If you retained this filter, all of the toilet objects for the project now display in the Workbook. If you changed the filter back to Sheet view, the Workbook shows data only for the active sheet; therefore, only 2 of the objects are shown. If this is the case, change the Workbook filter to Project view to view all 6 objects.
13. Click (Back) to return to the summary view. Navigate to an object:
14. On the Takeoff palette, right-click any toilet object, click Views, and click the sheet listed on the flyout menu.
QTO zooms in to the selected object on the associated view drawing. 15. On the Takeoff palette, click the selected object to enter editing mode. 16. Enter a more descriptive name, such as Entry Level South, and click ENTER.
Tip: In order to rename the objects by location, open the Navigator palette to see where the selected object is on the sheet.
17. Using the same method, rename the remaining objects, as shown.
Using an Area Takeoff Tool
In this exercise, you use a manual takeoff tool to yield an area measurement for carpet. Modify the sheet display:
1. On the Documents palette, under Floor Plans, select Sheet: A101 - Entry Level & Upper Level 1.
2. Click (Pan), and move the sheet to show the south portion of the lobby and corridor on the Entry Level.
Create a takeoff object with a polyline tool:
3. On the Takeoff palette, select Interiors Floor Finishes Floor, Carpet. 4. On the toolbar, click (Polyline Area Takeoff).
5. On the canvas, begin to trace the corridor walls by clicking to specify the start point and end point of your first line segment.
Tip: To draw a line that is perfectly horizontal or vertical, press and hold SHIFT while drawing.
6. Continue to specify points to trace the corridor walls and create a closed polygon, as shown. To close the polyline area, click near the start point or right-click.
Tip: To pan the drawing when you are in the process of tracing geometry, press and hold the SPACEBAR to switch from the takeoff tool to Pan mode. Pan the drawing until the geometry you need is in view. Release the SPACEBAR to return the takeoff tool to its original state, and complete the takeoff measurement.
7. In the Workbook, click the Interiors tab, and expand Floor Finishes Floor, Carpet. The carpet takeoff is recorded both in the Workbook and on the Takeoff palette.
Create a takeoff object with a rectangle tool:
8. Click (Pan), and pan to the left to display the south end of Upper Level 1. 9. On the Takeoff palette, select Interiors Floor Finishes Floor, Carpet. 10. On the toolbar, click (Rectangle Area Takeoff).
11. In Room 14, click one corner to specify the start point of the rectangle, move the cursor diagonally across the room, and click the opposite corner to specify the end point.
12. In the Workbook, double-click Floor, Carpet to view object data. 13. Make note of the area calculation listed for Floor, Carpet_2.
Next, you use an area backout tool to subtract from this area measurement. Using a Backout Takeoff Tool
Use the backout tools in QTO to refine takeoff data by subtracting from a previously calculated measurement or count. In this exercise, you use the Polyline Backout Takeoff tool to remove a portion of the carpet area measurement to account for the void created by the curved wall.
1. On the canvas, zoom in to the curved wall in Room 14. 2. On the toolbar, click (Polyline Backout Takeoff).
3. On the Contextual Tools palette, click , and draw an arc that traces the curved wall, as follows: • For the first point of the arc, specify the intersection of the curved wall and the wall on the left. • For the second point, specify the midpoint of the curved wall, as shown.
4. On the Contextual Tools palette, click , and draw a line segment that closes the semicircle.
When you complete the backout, the backout area is subtracted from the carpet area, and the Area value in the Workbook is updated.
The area measurement displayed on the canvas is updated as well.
5. Click (Back) in the upper-left corner of the Workbook to return to the summary view. Add Markup to a Sheet
In this exercise, you use markup tools to add a callout and text to a sheet. Add a callout to the curved wall:
1. On the Toolbar, click .
2. On the Contextual Tools palette, select 4 pt for the callout font size. 3. Place the callout:
• Specify a point on the right side of the curved wall as the start point. • Move the cursor up and to the right to specify the second point.
• In the text box, enter Is wall continuous from floor to ceiling?, and then click outside the box. 4. On the toolbar, click , and select the callout on the canvas.
Add a stamp:
6. Click View menu Fit to Window. 7. On the toolbar, click .
8. On the Contextual Tools palette, for Stamp, select Preliminary, and for Size, select 14 pt. 9. Specify a point near the top of the sheet to place the stamp.
10. On the toolbar, click , and select the stamp on the canvas. 11. Reposition the stamp as needed.
Add a legend:
12. On the Documents palette, for Sheet: A101 - Entry Level & Upper Level 1, select the Legend check box. Alternatively, you can click Document menu Legend to add a legend to the selected sheet. The legend is composed of a color block, an item label, and quantity information, showing the amount of the item that is used on the sheet. By default, legends show the primary quantity (Quantity 1) and associated unit for each item.
13. On the toolbar, click , and select the legend on the canvas.
With the legend selected, you can modify the legend settings on the Contextual Tools palette, and you can reposition the legend as needed.
