Point Cloud Exact Point (PCEXPT) ( Modeling )
Tool summary :
- PCEXPT stands for "Point Cloud Exact Point." It is a snap for locating points associated with point clouds.
- PCEXPT can be one of the Auto point modes that are used for Auto point location.
- You can also use PCEXPT to locate noticed points . As shown in the first example below, during point location, an EXPT point is marked with the text " Point Cloud Exact ".
- To check the end elevation of a point in a point cloud, you can Add Construction Line , select PCEXPT as the Locate option, then place your mouse pointer (
) so that the point location target ( 
) snaps to a point in the cloud. The X-Y-Z display tells the elevation.
- See the step-by-step instructions .

Example :
|
Point cloud exact points can appear in colors provided by the imported E57 point cloud file, or by a " Color " that you specify for a point cloud scan. Every colored dot shown here is a point from a cloud. |

Locating a point cloud point using PCEXPT :
1 . Begin this operation in Modeling .
1a : Invoke Add Construction Line or Add Member or any other tool that permits the use of PCEXPT as a Locate option.
2 . Various Locate options become active, and the status line prompts you to locate a point.
2a : Select the Point Cloud Exact Point icon or choose Locate > Point Cloude Exact Point or select ' PCEXPT ' on the Set Location Mode toolbar item or , if you want to use Auto point location, move your mouse pointer near a point cloud exact point as described in step 2b.
2b : Place the mouse pointer (
2c : Continue to perform the operation you began in step 1a.
Tip: For second point location (step 3 if these instructions were to continue), you can optionally type in a distance and/or angle to constrain the second point to the typed-in distance/angle from the first point. The distance/angle you type will be shown in brackets [ ] in the status line .
