How do point clouds work in Revit?

How do I navigate a point cloud in Revit?

Switch to the South elevation view and select the point cloud. Next, click Move in the contextual ribbon, and then move the point cloud vertically so that the bottom aligns with Level 1. Be aware that Revit will snap to the points in the point cloud and will find an alignment line at the bottom.

What is the purpose of point cloud in Autodesk?

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.

What can you do with a point cloud?

Point cloud data can be used to bring coordinates to life in the form of a 3D CAD (Computer-Aided Design) image. For example, if a point cloud has been collected from a highway, once the data is added to point cloud processing software, it can be transformed into a digital model of the road.

How accurate is a point cloud scan?

Whereas traditional surveying methods take one measurement every 30 seconds, a point cloud scan takes 976,000 points/second. This makes it one of the fastest and most accurate methods of measuring areas, especially in more complex buildings.

How do I get point cloud data?

The key factor in acquiring point cloud data is the access/visibility to scanned surfaces. In most cases, point clouds are obtained by visible access to real objects. This means that simply to cover all scanning positions takes time. Aligning laser scans taken from all these scanning positions can also be a problem.

What is point cloud BIM?

Fundamentally, point clouds bring BIM (and other forms of computer models) in touch with physical space. Rather than simply remaining guides or theoretical representations, point clouds provide the ability to effectively import 3D physical space into a digital format and inform/augment your existing digital models.

What is point cloud format?

Common point cloud binary formats include FLS (Faro), PCD (point cloud library), and LAS. Several other regularly used file types are capable of both ASCII and binary formats. These include PLY, FBX. E57 store data in both binary and ASCII, pulling many of the benefits of both together in a single file type.

What is the difference between voxel and point cloud?

“Voxels” are like pixels in 3D; think of voxel grids as quantized, fixed-sized point clouds. Whereas point clouds can have an infinite number of points anywhere in space with floating-point pixel coordinates, voxel grids are 3D grids in which each cell, or “voxel,” has a fixed size and discrete coordinates.
