ADA ramps and freeform line extraction

00:03

ReCap Pro now delivers the capability to extract additional 3D features from point cloud data,

00:09

such as ADA ramps, driveways, and atypical shapes.

00:14

You can save these extractions for future use and export the geometry to DXF, LandXML, and now CSV files for use in other applications.

00:26

To extract a 3D feature, such as an ADA ramp, with your point cloud view zoomed in and oriented to the area of the feature,

00:34

in the contextual tile menu, select Feature Extraction.

00:39

In the Feature Template browser, select the 3D tab, and in this case, select the ADA Corner Ramp.

00:46

Your cursor aligns to a single point in the template.

00:50

Press TAB to change the point your cursor aligns to.

00:54

Use your cursor to position the template in your project, and click to place the origin of the 3D feature.

01:01

Rotate the orientation and click to confirm once the template aligns with the geometry.

01:06

If placement does not align properly, simply press ESC.

01:11

A dialog box opens to confirm that you want to discard the changes.

01:16

Click Yes, then repeat the steps to place the feature in the correct location.

01:22

Next, adjust the template to fit the geometry.

01:26

Click and drag a point or line to move it.

01:30

To create a new point, click where you want the point to appear.

01:35

Move the cursor until the dotted line connects with an existing point in the template, then click to place the new line.

01:42

Zoom and rotate the view to adjust all points to match the point cloud feature.

01:48

When the template is in place, click Done to finish the extraction.

01:53

In the Project Browser, Features tab, under 3D Features, you now have the 3D feature saved for future use in the project.

02:04

If you have other ADA ramp features to extract, simply repeat the same steps.

02:10

This time, when you click Done, the extraction will be saved as ADA Corner Ramp 1.

02:17

You can also create a freeform template to capture the shape of a 3D feature that is not typical.

02:23

Open the Feature Template browser, select 3D, and then click Freeform.

02:30

Click in the point cloud to place the first point,

02:33

then move your cursor and continue to place points until you have sketched the entire feature.

02:40

When all adjustments are complete, click Done.

02:44

Your new 3D feature appears in the Project Browser.

02:48

Once an extraction is saved, you can easily make adjustments by clicking Edit next to the feature name.

02:55

Click Done to save the changes.

02:58

To export the extracted features, in the Project Browser, on the Features tab, hover the cursor over 3D Features and click Export All.

03:08

In the Export dialog, expand the File type drop-down to view the available options for export.

03:15

Select DXF, LandXML, or CSV files, and then click Export.

03:22

In this case, LandXML is selected.

03:26

Now, you can import the features you extracted from your point cloud into another program, such as Civil 3D.

03:34

During the import process, view and select the features you want to import.

03:39

Here, all features of the ADA Ramps and the freeform feature are imported and now appear in the Civil 3D drawing.

03:47

These expanded capabilities for extracting and exporting 3D features in Recap Pro

03:53

provide more flexibility and improve your efficiency when working with point clouds.
