Seed 1 and S eed 2—Change the U location of the
seed value on the first and second curves. If there
is a choice of directions, the direction indicated by
the seed points is the one used to create the fillet.

you replace the parent curves. Click the button,
then click the curve to replace the original first or
second curve.

Trimming a surface with a surface-surface intersection curve
This command creates a curve that is defined
by the intersection of two surfaces. You can use
surface-surface intersection curves for trimming
(page 1–1080).
If the sur faces i ntersect at two or more locations,
the intersection closest to the seed point is the one
that creates the curve.
Procedure
To create a surface-surface intersection curve:
1.
Turn on Create Surface-Surface
Intersection Curve in the NURBS toolbox, or
Surf x Surf on the Create
Curves rollout.
2. Click the first surface
, then the second.
If the two surfaces inte
rsect, a c urve that lies
along their intersection is created.

Tri m 1 and T rim 2—When on, trim a surface against
the intersectio

trimmed. Trim 1 tr ims the first parent sur face
you clicked, and Tr im 2 t rims the second parent
surface.
If the intersection curve does not pass completely
across a surface, trimming is impossible, and the
affected surf
ace is displayed in the error color
(orange by default).
