786 CHAPTER 23 PROJECTING THE COST: QUANTITY TAKEOFF
14. Click the Open drop-down menu in the top left of the QTO Manager, and select Open Cate-
15. Browse to the Mastering Categories.xml ﬁle again and open it. Once Civil 3D processes
your XML ﬁle, your QTO Manager s hould look similar to the following screen image.
Creating a fully developed category list is a bit time-consuming, but once it’s done, the list can be
shared with your entire ofﬁce so ever yone has the same data to use.
Keeping Tabs on the Model
Once you have a list of items that should be accounted for within your project, you have to assign
them to items in your drawing ﬁle. You can do this in any of the following ways:
◆ Assign pay items to simple items like blocks and lines.
◆ Assign pay items to Corridor components.
◆ Assign pay items to Pipe Network pipes and structures.
In the next few sections, you’ll look at each of these methods, along with some formula tools
that can be used to convert things such as linear items to individual quantity counts.
AutoCAD Objects as Pay Items
The most basic use of the QTO tools is to assign pay items to things like blocks and linework
within your drawing ﬁle. The QTO tools can be used to quantify tree plantings, sign posts, or area
items such as clearing and grubbing. In the following exercise, you’ll assign pay items to blocks as
well as to some closed polylines to see how areas can be quantiﬁed:
1. Open the Acad Objects in QTO.dwg ﬁle.
2. From the Analysis tab’s QTO panel, click the QTO Manager button to display the QTO
3. Expand the Favorites branch, right-click on CLEARING AND GRUBBING, and select
Assign Pay Item to Area as shown in Figure 23.5.
4. Enter O at the command line and press
to activate the Object option for assignment.
