Use NGon to create closed flat-sided or circular
splines with any number (N) of sides or vertices.
Examples of NGons
Procedure
To create an NGon:
1.
GototheCreatepanelandchoose
Shapes.
2. Click NGon.
3. Chooseacreationmethod.
4. Drag and release the mouse button in a
viewport to draw the N
Gon.

All spline-based shap
es share these parameters.
See
Splines (page 1–261) for an explanation of
these parameters.

parameters. See
Splines (page 1–261) for an
explanation of these parameters.
Parameters rollout
Once you have created an NGon, you can make
changes using the following parameters:
Radius—Specifies the NGon radius. You can use
either of two met hods to sp ecify the radius:
•
Inscr ibed—The radius from the center to the
corners of the NGon
•
Circum scr ibe d —The radius from the center to
the sides of the NGon.
Sides—Specifies the number of sides and vertices
used by the NGon. Range=3 to 100.
Co rn er Radius—Specifies the degree of rounding to
apply to the corners of the NGon. A setting of 0
specifies a standard unrounded corner.
Circula r—When on, specifies a circular N Gon.
Star Spline
Create panel > Shapes > Splines > Object Type rollout
>Star
Create menu > Shapes > Star
Use Star to create closed star-shaped splines with
any number of points. Star splines use two radiuses
to set the distance between the outer points and
inner valleys.
