Continuity adjustment

This command allows to force the tangency on the extremities of an open curve.

The operation consists in modifying the second (or next to last) control point of the curve by projecting it on the direction imposed. This function is used to adjust the tangency between two almost tangent curves.

Creation stages / Use:

Select the 2D sketch or 3D sketch > Operations > Continuity adjustment... command from the drop-down menu.

Select the profile near the extremity to modify.
Select the type of modification to be applied to the profile.
Select the type of influence.
Select the curve of reference.

	<p> </p> The Tolerance contextual command allows to modify this approximation.
	If the curve is not a Spline, it is converted.

Available Options:

Type:

Position: The extremity of the curve to modify is superposed to the reference curve.
Tangency: The extremity of the curve to modify is not moved, but it is bent to be tangent with the extremity of the reference curve.
Position and tangency: Both modifications are applied.

Influence:

Local: allows to confine the modifications near the considered extremity.
Distributed: allows to modify several control points, on a sliding scale way. This method is recommended when there is a large number of control points, in order to avoid a too strong variation of the curve. The influence length is measured on the control polygon in order to know which points will be modified.
