Point clouds are groups of data points generated by 3D scanners, often saved in .RCP or .RCS file formats. In AutoCAD, you can attach point clouds via the Insert Tab under the Reference Panel, and they can be added as either Xrefs or images based on your project’s requirements.
To align your work with the point cloud, use the Object option in the UCS (User Coordinate System) command to align the active UCS to a plane within the point cloud. Additionally, the Dynamic UCS feature automatically aligns to the plane of the point cloud, making it easier to manipulate and interact with the 3D data.
The Display Panel gives you control over various aspects of point cloud visualisation. You can adjust the point size to change the scale of individual points and modify the point density to fine-tune how the point cloud is displayed. The panel also provides several navigation options, such as Perspective, 3D Orbit, 3D Swivel, and 3D Walk, allowing you to explore and interact with the point cloud from multiple angles and in different viewing modes. These tools enhance your ability to work with point clouds, providing flexibility and precision in your design process.
Attaching a point cloud in AutoCAD is simple and can be done in a few steps:
- Navigate to the Insert Tab and select Attach under the Reference Panel.
- In the Select Reference File dialogue box, expand the list and choose the appropriate .RCP or .RCS Autodesk Point Cloud data files.
- Review the details in the Attach Point Cloud dialogue box to ensure all relevant information is correct.
- Set any necessary options to suit your needs and click OK to successfully attach the point cloud to your project
In the Visualisation Color Map settings, you can customise various colour scheme options to improve the visual representation of your point cloud data. One key feature is the Color Ramp, which lets you adjust the gradient of colours applied to the point cloud, providing a clearer view of your data.
When working with point clouds alongside other geometry in a drawing, it can be difficult to view objects that are hidden behind the point cloud. The Transparency tool, located in the Point Cloud contextual tab under the Visualisation Panel, allows you to adjust the transparency of the Point Cloud.
By controlling how much of the point cloud is visible, you can make it easier to see and interact with the underlying geometry, ensuring a smoother workflow and more precise edits.
Some important features when working with point clouds in AutoCAD include the ability to:
- Save a Named Crop State: You can save a crop state for easy access later. By defining a boundary, you can crop the point cloud to focus on specific areas, improving your workflow and precision.
- Create a Section: You can create a section of the point cloud in your desired orientation, helping to isolate and work with specific parts of the data more efficiently.
- Set Up Section Lines from Point Clouds: With the Live Section option activated in the contextual tab, section lines can be generated directly from the point cloud. These section lines can then be extracted as needed, allowing for flexible visualization and manipulation of the point cloud data.
