Curve-Curve Intersec tion Point 1223
U Position and V Position—If the point is on the
surface, these coordinates specify the point’s
location, based on the surface’s local UV
coordinates.
On S u rf a ce—Specifies that the point lies on the
surface, at the location specified by U Position and
V Position.
If the poin t lies on the surface, you can move it
using the Move t ransfor m. You can also move it
using the Move Surface Point button. See Editing
Point Sub-Objects (page 1–1123).Eitherway,this
updates the U Position and V Position values.
Offset—Moves the point according to a relative
(object space) X,Y,Z lo cation.
X Offset, Y Offset, and Z Offset—Specify the object
space location of the offset surface point.
Normal—Moves the point along the direction of
the surface’s normal.
Distance—Specifies the distance from the surface,
along the normal. Negative values move the point
opposite to the normal.
Tangent—Moves the point along the tangent of the
UV position.
U Tangent and V Tangent—Specify the distance
from the surface along the tangents at U and V.
Replace Base Sur face—(Only at modification
time.) Lets you replace the parent surface. Click
the button, then click the new surface on which to
base the surface point.

Create Curve-Curve Point button
This command creates a dependen t point at the
intersection of two curves.
Procedure
To crea te a dependent cur ve-curv e point:
1.
Turn on Cur ve-Cur ve, then drag from the first
curve to the second.
If the cur ves do not intersect, the point is
orange, an invalid dependent point.

between the two curves. You can use the
curve-curve parameters to trim the parent
curves.
2. Right-click to end the create operation.
