Point Set Deviation

The PointDeviation command uses colored line hairs to display the distance between geometry objects.

Measured objects can be point objects, point clouds, surfaces, polysurfaces, extrusions, and meshes.
Target objects can be curves, surfaces, polysurfaces, extrusions, and meshes.
The command extracts vertices from meshes and sample points from surfaces/polysurfaces/extrusions to measure.

Steps

Select objects to measure, and press Enter.
Select the target objects.
Change options in the Point Deviation panel.

Point Deviation options

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.

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.

Apply

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 selected surface.

Median distance

The median distance between the selected points and the selected surface.

Standard deviation

The standard deviation distance between the selected points and the selected surface.

Start

Run the PointDeviation command to start a new measurement.

End

Stop measuring the current objects.

Command-line option

Visible (Yes / No / Toggle)

Display/hide the Point Deviation panel, or change its visibility.
