Flip Trim—
Reverses the direction of the trim.
Flip Normals—Turn on to reverse the direction of
the fillet surface’s norma ls.
Fillet Surface rollout (m odification time)
Start R adius and End R adius—Set the radius used
todefinethefilletatthefirstsurfaceyouchose
and the second surface you chose, respectively.
The radiuses control the size of the fillet surface.
Default=10.0.

setting is unavailable. Default=on.

This g roup box controls the radius of the fillet.

have curvature to them .
Linear—When chosen (the default), the radius is
always 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.
Flip Trim—Reverses the direction of the trim.
Replace First Surface and Replace Second
Surf ace—
Let you replace the parent surfaces. Click
a button, then click the surface to replace the
original first or second sur face.
