Fillet Surface 1217
Procedure
To create a fillet sur fa ce:
1.
InaNURBSobject,turnonFilletonthe
Create Surfaces rollout or Create Fillet Surface
in the toolbox.
2. Click to choose the first p
arent surface, then
click to choose the second parent surface.
Potential parent surfaces are highlighted in blue
as you move the mouse in
aviewport.
The fillet surface is cr
eated. If the fi l let surface
can’tbecreated,adefaulterrorsurfaceis
displayed (by default, the error surface displays
as orange).

This g roup box controls the radius of the fillet.

Linear—When chosen (the default), the radius is
linear.
Cu bic—When chosen , the radius is treated as a
cubic funct ion, allowing it to change based on the
parent surface’s geometry.
Seeds group
These spinners adjust the seed values for the fillet
surface.Ifthereismorethanonewaytoconstruct
the fillet, the software uses the seed values to
choose the nearest edge for that sur face.
Surf ace 1 X—Sets the loca l X coordinate of the seed
onthefirstsurfaceyouchose.
Surf ace 1 Y —Sets the lo cal Y coordinate of the seed
onthefirstsurfaceyouchose.
Surf ace 2 X—Sets the loca l X coordinate of the seed
on the second surface you chose.
Surf ace 2 Y —Sets the lo cal Y coordinate of the seed
on the second surface you chose.
Trim First Surface and Trim S econd Sur face
groups
For each of the parent sur f aces, these controls
affect t rimming.
Tri m Su rface—Trims the p arent surface at the edge
of the fillet.
