See Add Point-Cloud

Use a Point Cloud to:

Import-data as a text-file.

Use the Point-Cloud dialog-box to import data.

Typically, the data are coordinates of a cam-profile, which are measured with a Coordinate Measurement Machine (CMM). The measurement data are taken 'as is'. Numerical techniques calculate motion-derivatives, but the higher derivatives are usually noisy.

Fit-a-Curve to the imported-data.

Use Point-Cloud dialog-box to fit a Curve to the Imported-Data.

The Curve is a continuous-function that is a good-fit to the imported-data. We use the continuous-function to evaluate motion-derivatives, which are usually smooth.
