This task shows how to create curves from a scan or a set of scans.
The Curve from Scans action tries to create curves
- with the defined tolerance,
- with the least possible number of segments of the least possible
order.
The Curve from Scans action proposes a dynamic definition of
split points. |

More information is available in
Parameters for Curve from Scan. |

Open the
CurveFromScan.CATPart model from the samples directory. For a better

In the dialog box, click
icon to display the curvature analysis:

-
Release
and now click
to display the maximum deviation
and
to display the order and the number of segments:

-
Click OK to exit the action and create the
curve(s).
Curve.x elements are created in the specification tree. The
