How do you extract points from ReCap?
To export smaller areas of a ReCap point cloud: In ReCap define a “Limit Box” or use the Project Navigator to hide unnecessary scans. After the view is isolated, use the “Save as” button to save a new (structured) point cloud. Alternatively, use the Export button to save RCP, RCS, e57 or PTS.
How do I reduce point cloud size?
Point cloud file sizes can be drastically reduced by changing the spacing between the unified points. Specify this point spacing during the export to RCP\RCS process. Start the Export command and specify what the exported file will be called and where it will be saved.
How do I extract lines in Autocad?
To Extract Curves from Surfaces, Solids, and Faces of Solids Click Surface tab Curves panel Extract Isolines. Find. Select a surface, solid, or face. Click to extract an isoline curve represented by the preview line. If necessary, enter D the direction in which the curves are detected. Press Enter to end the command.
How do I turn off point cloud in Autocad?

What is ReCap intensity clipping?
Sets the size of the point cloud by setting distance and intensity ranges. Intensity Clipping: Determines the range of intensity values to allow for included points.
What is point cloud AutoCAD?
A point cloud is a large collection of points acquired by 3D laser scanners or other technologies to create 3D representations of existing structures. Point cloud files support the design process by providing real-world context where you can recreate the referenced objects or insert additional models.
How do you decimate a point cloud?
The decimation process is very easy : Open your Recap file (add scans and index first if necessary) Click Export. Give your file a name. Click the settings button. Move the slider to adjust your point decimation – you might use around 50mm decimation for a lot of site applications. Save the file.
How big is a point cloud?
Depending on the nature of the project, that is likely somewhere between 5mm and 25mm between data points.
What is point cloud decimation?
Point Cloud Decimation A point cloud data consists of millions of small points, sometimes even more than what is necessary. Decimation is the process of discarding points from the data to improve performance and reduce usage of disk. Decimate point cloud command reduces the size of point clouds.
How do I extract edges of solid in Autocad?

How do I use point cloud data in AutoCAD?
To Attach a Point Cloud to a Drawing Click Insert tab > Point Cloud panel > Attach. In the Select Point Cloud File dialog box, find and select a scan (RCS) or reality capture project file (RCP) to attach. In the Attach Point Cloud dialog box, specify your preferences for insertion point, scale, and rotation.
What is decimation grid in ReCap?
Decimation grid: Controls the number of points to import by specifying the smallest cubic volume that a single point can occupy. Lower values improve the quality of the point cloud but also increase the file size.
How do you rotate a limit box ReCap?
Rotation. To rotate the Limit Box, move the cursor so that an edge is highlighted and hold down the Ctrl key. Next, click and drag. The Limit Box rotates about an axis that is parallel to the edge you highlighted.
How do I open a point cloud file?

How does point cloud work?
A point cloud is a collection of many small data points. These points exist within three dimensions, with each one having X, Y and Z coordinates. Each point represents a portion of a surface within a certain area, such as an engineering work site. You can think of these points similarly to pixels within a picture.

How do you decimate a point cloud in a cyclone?
Steven’s correct if you highlight the cloud then press Edit Object > Reduce Point Cloud you’ll get the following options. This will decimate the cloud but still allow for .
How are point clouds measured?
Point clouds are most commonly generated using 3D laser scanners and LiDAR (light detection and ranging) technology and techniques. Here, each point represents a single laser scan measurement. These scans are then stitched together, creating a complete capture of a scene, using a process called ‘registration’.
What is point cloud format?
A point cloud is a set of data points in space. The points may represent a 3D shape or object. Each point position has its set of Cartesian coordinates (X, Y, Z). Point clouds are generally produced by 3D scanners or by photogrammetry software, which measure many points on the external surfaces of objects around them.
How do I create a point cloud?
To Create Point Cloud Objects In Toolspace, on the Prospector tab, right-click Point Cloud Create Point Cloud. On the Information page of the Create Point Cloud wizard, enter the required information about the new point cloud object.
