How does a point cloud work 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.
How to change the direction of a point cloud?
You can also use the 3DSWIVEL or 3DWALK commands to change your viewing direction. Use the 3DORBIT command in conjunction with the ORBITAUTOTARGET system variable to set a target point when orbiting about a point cloud.
How to set a target point on a point cloud?
Use the 3DORBIT command in conjunction with the ORBITAUTOTARGET system variable to set a target point when orbiting about a point cloud. Use the Object option of the UCS command to align the UCS with the nearest point on a point cloud or one of its planar segments (if the point cloud includes segmentation data from Autodesk ReCap).
Where does the data in a point cloud come from?
Point clouds are derived from raw data scanned from physical objects such as building exteriors and interiors, process plants, topographies, and manufactured items. After you collect the raw data, it must be converted to readable point cloud files.
How can I extract a point from a point cloud?
You can extract the point object at the intersection between three planar segments in a point cloud. You can extract the centerline of a detected cylindrical segment in a point cloud. You can section a point cloud and extract 2D geometry from point cloud segments.
How to determine if a point is inside a quadrilateral?
Add the angles together. If they equal (or nearly equal, depending on the error tolerance of the code) 360, the point is inside the quadrilateral. If the sum is less than 360, the point is outside. However, this might only work with convex quadrilaterals.
