How to snap to the nearest point in a point cloud, to a point on a planar segment on a point cloud, or perpendicular to a planar segment on a point cloud.
You can use 3D object snaps when working with point clouds. Some of these object snaps detect clusters of points that constitute a plane on the point cloud 3D model; these snaps require segmentation data in the scan file, obtained during processing by Autodesk ReCap. When object snaps are enabled, a glyph is displayed at the detected object snap point. Each 3D object snap for point clouds displays a different glyph.
If a point cloud scan file contains segmentation data, it's planar segments are identified by a transparent rectangle aligned parallel to the intersection of the plane with WCS when a snap point is detected.
Object snap settings may be controlled from the 3D Object Snap settings pop-up menu on the status bar.
To Snap to the Nearest Point in a Point Cloud
You can snap to a point on a point cloud whether or not it contains segmentation data from ReCap processing.
To Snap to the Nearest Point on a Planar Segment
If a point cloud contains segmentation data from ReCap processing, you can snap to the nearest point on a planar segment. When a point is detected that is part of a planar segment, the snap connects to the plane of that segment. The planar segment will display as you acquire the point if segment highlighting is turned on.
To Snap Perpendicular to a Planar Segment
If a point cloud contains segmentation data from ReCap processing, you can snap perpendicular to a planar segment. When a point is detected that belongs to a planar segment, the snap connects to it from a point perpendicular to the plane of that segment (similar to a snap perpendicular to the face of a solid). The planar segment will display as you acquire the point if segment highlighting is turned on.
