Editing a Surface Boundary

	This task explains how to modify a surface boundary as created in Creating Free Form Curves on Surfaces using its control points.
	Open the FreeStyle_Part_29.CATPart document.
	Select the surface boundary you wish to edit.
	Click the `Control Points` icon . Control points and lines are displayed along that boundary.

	By default all control points are selected. Click a specific point to deform the boundary at this point only, or select a set of points using the Ctrl-key or Shift-key while clicking (multi-selection capabilities).
	Modify the boundary pulling on its control points or the mesh line.

	Click `OK` in the Control Points dialog box. The boundary is modified.

	Only the boundary and its control points are modified. Any other boundary of the surface is not affected by these modifications. See also Using Control Points.
	Capabilities are available: from the contextual menu when right-clicking a control point, from the Dashboard: datum creation, auto detection, attenuation, continuities and orders. specified through the FreeStyle Settings
