- Select
Edit NURBS > Round Tool.
- Drag a selection box across the common
edges between surfaces.
- When you click a common edge, a radius
manipulator appears. Drag the handles at the ends of the manipulator
arms to change the rounding radius.
To deselect an edge,
click the manipulator on the edge and press .
- When you are done marking edges to be
rounded, press .
You can edit the radii
of the fillets after you create them by selecting the Round node
and using the channel box, attribute editor, or Show
Manipulator tool.
If a fillet cannot be
built with the current radius, the manipulator for that edge is
drawn in red.
Notes
- Overlapping radii will fail or create
unpredictable results.
You can correct this
by editing the radii with the Show Manipulator tool after
the fillets are created. If the angle between the two surfaces is
less than 15 degrees or greater than 165 degrees, the fillets produced
might be inadequate.
- The edges you round must be from separate
surfaces.
- If the edges have different lengths,
a fillet surface will be created only for the shorter edge.
- Corners are points where pairs of edges
meet. You cannot use the Round Tool on
more than three pairs of corners.
For example, you can
use the Round Tool on all edges of
a cube, but you can not use it on the tip of a pyramid, where four
edge pairs meet at the top.
- Acute corners may fail as the fillets
begin to self-intersect.
- The
radius manipulator approximates the profile of the fillet only when the
surfaces meet at an angle of nearly 90 degrees.
