Tension
This will only affect the Cissoid and Strophoid types. With the Cissoid, the larger the value you enter,
the more the two arcs are pulled together on both the left and the right of the axis of symmetry.
Increasing the Tension value on the Strophoid object has a similar effect to when used on the Cissoid.
The arcs are pulled up further as the value is increased. The loop also becomes narrower.
Various Cissoid objects with tension values of
50, 6 and 2.
Various Strophoids with tension values of 2, 6
and 10.
Plane
With this option you choose in which of the three planes the spline primitive is created.
Reverse
Enable this option to reverse the spline’s points.
Intermediate Points, Number, Angle
These interpolation settings dene how the intermediate points of the spline are produced. For more
information on these settings, look up ‘interpolation, spline’ in the index.
Cogwheel
