Fillet a Chain of Curves (3D/2D)
Insert 
Wireframe (Part Level)
Insert Geometry > Fillets (Sketch/Sheet
Level)
Use this command at the Part, Sketch and Drawing Sheet
Level to create fillets of a specified radius between a chain of curves.
There will be a fillet between each adjacent curve in the
chain. First
select the chain of curves to fillet and then specify the radius.
Use designer arcs - Check this box to use a designer arc instead of a traditional circular arc. A designer arc is a NURB curve that matches the tangency of the arc but has zero curvature at the end points. See Applying VX CAD - Using Designer Arcs for more information.
Trim original curves - Check this box to trim the original curves. Otherwise, only the fillet geometry is added. No trimming will occur.
Extension
(Part Level Only) - Use this option to control the path of the points
if the they go beyond the end of the curve.
Linear - The extension follows a linear path.
Arc - The extension follows an arc path in the direction of curvature.
Reflect - The extension follows a reflective path opposite the
direction of curvature.
