The PointDeviation command uses colored line hairs to visualize the distance between geometry objects.
-
Measured objects can be point objects, point clouds, curves, polylines, surfaces, polysurfaces, extrusions, meshes, and SubD.
Point objects, mesh vertices, and cloud points are directly used to measure. Analysis mesh vertices are used for other object types.
-
Target objects can be curves, surfaces, polysurfaces, extrusions, and meshes.
Steps
Point Deviation panel
Run the PointDeviation command to start a new measurement.
Stop measuring the current objects.
Options
Ignore
Points beyond this distance are ignored.
Bad point
Points beyond this distance are colored red or ignored.
Good point
Points closer than this distance are colored blue.
- Red numbers indicate the distances entered are invalid. For example, the bad point distance is smaller than the good point distance.
On surface
Points on the surface are colored blue.
Proximity angle
Points qualify for display if the hair line is this close to the normal direction on either the curve or the surface. Default is 1 degree. No points disqualify at 180.
Hair scale
The hair is exaggerated by this factor from the actual distance to the curve or surface. Default is 10.
Display hair
Display the hair line for each qualifying point.
Make hair permanent
Create a line object when the command terminates. Line objects are created on layers with names "Point Test <color>".
Automatically apply changes
Update the hair display interactively when options are changed.
Update the hair display manually when Automatically apply changes is disabled.
Statistics
Point count
The number of points.
Mean distance
The mean distance between the selected points and the target object.
Median distance
The median distance between the selected points and the target object.
Standard deviation
The standard deviation distance between the selected points and the target object.
Maximum distance
The distance from the farthest point to the target object.
Minimum distance
The distance from the nearest point to the target object.

Command-line option
Visible (Yes / No / Toggle)
Displays or hides the Point Deviation panel, or change its visibility.
CurveDivisions (Curve-only)
Specifies how many sample points to spread along a measured curve to evaluate deviation.
- If the curve to measure is pre-selected, this option will not appear. The previous setting is applied.
- When a line or polyline is measured, segment endpoints are also evaluated.
