(Create 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.
If the surfaces intersect at two or more locations, the intersection closest to the seed point is the one that creates the
curve.
Procedures
To create a surface-surface intersection curve:
The NURBS object must contain two surfaces that intersect.
- In the NURBS toolbox, turn on (Create Surface-Surface Intersection Curve).
- Click the first surface, then the second.
If the two surfaces intersect, a curve that lies along their intersection is created.

Surf-Surf Intersection Curve rollout (creation time)
Trim Controls group
- Trim 1 / Trim 2
-
When on, trim a surface against the intersection curve. When off, the surface isn’t trimmed. Trim 1 trims the first parent
surface you clicked, and Trim 2 trims the second parent surface.
If the intersection curve does not pass completely across a surface, trimming is impossible, and the affected surface is displayed
in the error color (orange by default).
- Flip Trim 1 / Flip Trim 2
-
When on, trim the associated surface in the opposite direction.
- U Seed / V Seed
-
Change the UV location of the seed value on surface 1, the first surface you clicked. If there is a choice of intersections,
the intersection closest to the seed point is the one used to create the curve.

Let you replace the parent surfaces. Click a button, then click the surface to replace the original first or second surface.
