Linear feature extraction settings in ReCap Pro

00:04

In ReCap Pro, Linear Feature Extraction allows you to extract linear features,

00:09

such as curbs and gutters, from a point cloud dataset.

00:13

Published ReCap point cloud projects have access to extraction tools in the Autodesk Construction Cloud viewer.

00:20

Before you extract a linear feature, the feature’s shape must be defined.

00:25

From a web browser, navigate to a ReCap project that has already been published to the cloud

00:30

with a linear feature extraction already in progress.

00:34

From the toolbar, click Linear Feature Extraction.

00:37

Then, select Feature Extraction Settings.

00:40

This displays the Feature Extraction Settings dialog.

00:45

Here, you can adjust the Alignment Algorithm Threshold.

00:48

This specifies the confidence threshold of the reference data to continue linear feature extraction.

00:54

If the value during extraction becomes lower than this baseline,

00:57

auto extraction will pause.

00:60

Once paused, you will be prompted to either stop the extraction and adjust the cross section,

01:04

or to ignore the pause and continue extraction.

01:08

From the dialog, you can also adjust the step interval.

01:12

This is the distance between each cross section during extraction.

01:17

Finally, you can also specify the depth of the cross section,

01:20

which is the depth of view as seen in the Cross Section View.
