Use quantification and selection sets with Data Exchange

00:04

In Navisworks, the Quantification feature helps you perform takeoffs to estimate materials,

00:09

measure areas, and count building components for construction and renovation projects.

00:16

The Navisworks Connector for Data Exchange can be used to help you with quantification.

00:22

Using loaded data exchanges instead of aggregated or native files,

00:27

you can create selection sets and perform takeoffs as you normally would.

00:32

Begin with a model open in Navisworks that has data exchanges already loaded.

00:38

You can see in the Selection Tree that this example has a surface, a structural model,

00:43

and an architectural model already loaded.

00:47

From the ribbon, Home tab, select Quantification.

00:52

Both the Quantification Workbook and the Sheet Browser open.

00:57

The workbook is the main workspace that contains the object data for the takeoffs.

01:03

From the workbook, click Project Setup.

01:07

A Quantification Getting Started dialog might display, prompting you to view tutorials.

01:13

Click Remind me later.

01:17

Next, in the Quantification Setup Wizard, select a catalog.

01:22

You can use a listed catalog or a custom catalog to define items and resources in your project.

01:29

With a catalog selected, click Next.

01:33

Select the unit of measurement you want to use in your project.

01:37

Click Next. Select the model properties you want to include in the takeoff, or keep them all selected, as in this example.

01:47

Click Next.

01:49

With Quantification ready to create the database, click Finish to complete the setup.

01:55

The wizard closes, and the catalog items display in the Quantification Workbook.

02:02

Next, creating selection sets within your data exchanges can help you to organize the data

02:08

so that you can focus in on only what you need.

02:11

Similar to other Navisworks workflows, you can can use selection sets when working with any data exchanges,

02:18

irrespective of quantification as in this example.

02:23

To create a selection set, in the Scene View, zoom into and orbit the model.

02:28

You can hide the objects in the current selection so that they are not drawn in the Scene View.

02:35

This is useful when you want to remove specific parts of the model that might occlude your view of a room or another specific object.

02:43

For example, right-click one of the curtain panels and select Hide.

02:49

Zoom into the model to navigate to a specific object, such as a door.

02:55

Now, to select all of these same doors, from the ribbon, Select and Search panel, expand the Select Same drop-down.

03:04

Click Same Name.

03:07

In the Selection Tree, all objects with same name as the currently selected item—in this case, the doors—highlight.

03:15

You can also navigate the model to verify that the doors are highlighted as being selected throughout the model.

03:23

Note that you could also select objects in the Properties of the Data Exchange and create search sets there.

03:30

With all the objects highlighted that you want to include in the selection set, in the ribbon, click Save Selection.

03:38

The Sets window displays.

03:41

Click the selection set name, enter a new name for your selection set, and then press ENTER.

03:49

Back in the Quantification Workbook, under Items, navigate to your newly created selection set.

03:56

Select one of the highlighted items, which in this case are under Exterior Doors.

04:02

As soon as you do, the Rollup pane displays a summary of the selected takeoff items,

04:08

and the Takeoff pane displays all takeoff items.

04:12

From here, you can begin working with this takeoff data as you normally would.
