Chamfer Curve 1163
Mirror Axis group
The Mirror Axis buttons control the direction in
which the original curve is mirrored.
You can’t transform the mirror curve directly (that
would simply t ransform the mirror curve
and its
parent curve at t he same time). You transform it
by t r ansforming its gizmo. By using transforms
you can mirror about an arbitrary axis, rather
than using one of the Mirror Axis presets. When
you t ransform a mirror curve, you are actually
transforming the mirror plane, so Rotate has the
effect of rotating the plane about which the curve
is mirrored. (This is like rotati ng the mirror gizmo
in the Mirror modifier.)
Offset—Controls the mirror’s distance from the
original curve.
This parameter is animatable.
Replace Base Curve—Lets you replace the parent
curve. Click the button, then click the curve to
replace the original curve.

Creating chamfers between two original curves
Procedure
To creat e a chamf er cu rve :
1.
In a NURBS object that contains at least
two curves, turn on Chamfer.
Tip: Make sure the curves intersect before you
begin to create th
echamfer.
2. Click one curve nea
rtheendthatyouwant
to connect. The end that w i ll b e connected
is highlighted. Without releasing the mouse
button, drag to th
eendoftheothercurvethat
you want to connect. When the end that will
be connected is highlighted, release the mouse
button.
Achamfercurve
is created. Changing the
position or the curvature of either parent curve
can change the chamfer as well.
The parent cur ves must be coplanar. The
chamfer is not
necessarily connected at the
endpoints of the parent curves: you can
adjust its position with the chamfer’s Length
parameters.
3. Adjust the ch
amfer parameters.
