Delete Points
The Home tab offers several methods to delete points. Points are not considered Objects because the are included within a Point Group. For that reason they require a special selection method:
-
From the menu, select Delete Points
, or press Alt+D.
Points can also be deleted within proximity to a reference group. To do so select Delete Points by Proximity to Reference Group. This utility will allow you to select a set of reference points and detect points within a specified proximity to those points. This is a great way to remove duplicate points.
Using Auto-Vectors/Point Pairs for Point deletion
An alternative to direct point selection to remove outliers is to take advantage of relationships and the auto-vectors they can create. In many cases the deviation vectors can be used to effectively identify bad measurements. When a relationship is displaying Auto-vectors the vectors are directly tied to the points that generate them and can be used for this purpose.
To delete points using vectors:
-
Select Delete > Auto-Vectors/Points Pairs
-
Select the vectors to delete by holding shift and rectangle selecting in the graphics or using one of the other graphical selection tools (the vector end points is used for selection). This will remove both the vector and the corresponding cloud point.
