Move the pointer over an existing curve, double-click it, then right-click and
select Impose Tangency.
Two sets of handles are displayed:
- An arrow representing the tangency vector.
- Two circles, each having a zone for this vector.
- Adjust the tangency constraint
by doing any of the following:
- To modify the direction of the tangency vector, drag the circle.
- To invert the direction of the tangency vector, double-click the arrow.
- To modify the amplitude of the tangency vector, drag the arrow.
- To define the constraint according to an external element, right-click any of the handles.
- Select one of the options from the context menu.
- Once you are satisfied with the tangency constraint you
imposed, release the handle and move the pointer around to
display the curve preview.
You are now ready to create a new
point.
