Curve-Curve Intersection Point 1225

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 Surface—(Only at modification

time.) Lets you replace the parent surface. Click

the button, then click t he new surface on which to

base the sur face point.

Create Curve-Curve Point button

This command creates a dependent point at the

intersection of two curves.

Procedure

To crea te a dependent curv e-cu r ve point :

Turn on Curve-Curve, then drag from the first

cur ve to the second.

If the curves do not intersect, the point is

orange, an in valid dependent point.

The point is created at the nearest intersection

between the two curves. You can use t he

cur ve-curve parameters to trim the parent

cur ves.

2. Right-click to end the create operation.

Interf ace

While a curve-curve point sub-object is selected,

the Curve-Curve Inte rsection rollout appears.

TrimFirstCurveandTrimSecondCurvegroups

These two groups let you control how the parent

curves are t rimmed. T he controls are the same

in each. "First" and "second" refer to the order in

which you picked the parent cur ves.
