Job: Shape Constraint - Controlling the curve continuity

Controlling the curve continuity in the selected location

When editing a cruve with the Curve Shape Constraint command, you can set the continuity conditions of the selected curve at its common point with another curve.

Proceed as follows:

1 Select the curve by clicking on the location you want to edit. A handle will be displayed on the curve in the location you selected.

You are now enabled to change the curve shape by moving the location you selected on it or by modifying the tangency conditions in the same location.

2 Click on More Options and select the type of continuity you want to apply from the Snap drop-down list:

Positional — positional continuity: the two points coincide and no condition is applied to the tangent vectors of the two curves in the common point.
Tangent — tangency continuity: the two points coincide and the tangent vectors of the two curves in the common point lie on the same direction.
Perpendicular — perpendicularity continuity: the two points coincide and the tangent vectors of the two curves in the common point are perpendicular.

3 Drag the selected location of the curve and snap it to the other curve you want to apply the continuity conditions to. The continuity type you specified will be applied.
