Surface-Surface Intersection Curve 1167
Seed 1 a nd 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 fi llet.
Fillet Curve rollout (modification time)
Radius—The r adius of the fil let arc in the current
3ds Max units. Default=10.0.
Tip: If the fillet you initially create is in an error
state,oftenthisisbecausetheradiusisnotlarge
enough to bridge the distance between the two
cur ves. Increasing the Radius va lue g ives you a
correct fi l let. The fillet b ecomes an arc displayed
in the dependent object color (green by default).

straight line in the error color (orange by default).
TrimFirstCurveandTrimSecondCurvegroups
These two group boxes let you control how the
parent curves are trimmed. The controls are the
same in each. "First" and "second" refer to the
order in which you picked the parent curves.
Trim Curv eWhen on (the default), trims the

parent isn’t tr immed.
Flip Trim—When on, trims in the opposite
direction.
Seed 1 a nd S eed 2 Change the U location of the
seed value on t he first a nd second curves. If there
is a choice of directions, the direction indicated by
the seed points is the one used to create the fillet.
ReplaceFirstCurveandReplaceSecondCurveLet
you replace the parent curves. Click the button,
then click the curve to replace the original first or
second cu rve.

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
