Produces curves-on-surface from horizon lines as seen from a point in space or from a direction.
Horizon Control
-
-
Choose how to project the horizon line onto the surfaces.
– Use the horizon as seen from a certain point in space.
– View the horizon from a certain direction. With this technique, the “sightlines” are parallel and the viewpoint is infinity.
Note
If the horizon does not cross the surfaces when viewed from this point or direction, the tool does not create any curves on surface.
-
-
The point in space from which to look at the picked surfaces and the horizon.
You can set this point with the viewpoint locator when you use the tool.

-
Enter the name of a point to position/align the manipulator with it. (You can also click a point to align the manipulator with it. Or you can select the point and the surface
before selecting the tool.)

Enter the name of a vector to position/align the manipulator with it. (You can also click a vector to align the manipulator with it. Or you can select the vector and the
surface before selecting the tool.)

Control Options
-
-
Save the history of the new curves-on-surface for later editing. If you turn on, you can modify the surfaces and the curves-on-surface update.
-
-
Update the curves-on-surface as you change the values in the window.
Buttons
-
-
When . is off, use this button to update the curves on surface to correspond to the current options.
-
-
Undo all the changes made by the tool and return to the original surface.
-
-
Finish creating curves-on-surface on the current surface and prompt for a new surface to evaluate.
