Clash detection with data exchanges

00:04

A data exchange in the Navisworks Connector represents a subset of your design stored in a neutral format in the cloud.

00:11

With it, you can access relevant geometry and properties of your model,

00:15

either as a whole or at a granular level, to create custom workflows.

00:20

Once you have loaded data exchanges into Navisworks, you can perform clash detections.

00:26

From the ribbon, click Clash Detective.

00:29

The Clash Detective window displays.

00:32

To define a new clash test, click Add Test.

00:36

A new test displays in a table.

00:39

On the Select tab, two selection panes display,

00:42

both with the same data hierarchy as in the Selection Tree.

00:46

In each pane, select the items you want to compare.

00:50

You can select entire Data Exchange models, or expand a model and choose specific levels, categories, or families

00:58

to test against each other.

01:01

Below the selection panes are additional settings, if you wish.

01:05

Once you are ready, click Run Test.

01:08

Once the test has run successfully, the Results tab displays the list of clashes, all of which display a status of New.

01:16

Select a clash to view it in the Scene View.

01:19

Zoom and orbit the model to review the selected clash.

01:23

In this example, you can see that the wall is not meeting the floor above it properly, and instead, is cutting through it.

01:31

Once you are finished, return to the Connector interface.

01:35

Click Refresh to review if any data exchanges you loaded into Navisworks have newer versions available.

01:42

The version icon displays a blue dot to indicate that a data exchange has a newer version available.

01:48

Select the data exchange that needs to be updated.

01:52

Click More, and then select Load the latest.

01:56

The Data Exchange downloads the latest version, which again, is indicated in the Connector interface list.

02:03

Back in the Clash Detective, select Update all.

02:07

In the Results tab, the status of the clashes changes to Active.

02:12

Select a clash to review it.

02:14

Now you can see that the problem has been resolved, and the wall is correctly meeting the floor.
