Co rner—
Produces a sharp point. The spline is
linear to either side of the vertex.
Smooth—Produces a smooth, nonadjustable curve
through the vertex. The amount of curvature is set
bythespacingofthevertices.
Drag Type group
Sets the type of vertex you create when you drag a
vertex location. The vertex is located at the cursor
position where you first press the mouse button.
Thedirectionanddistancethatyoudragareused
only when creating Bezier vertices.
Co rner—Produces a sharp point. The spline is

Smooth—Produces a smooth, nonadjustable curve
through the vertex. The amount of curvature are
set by the spacing of t he vertices.
Bezier—Produces a s mooth, adjustable curve
through the vertex. The amount of curvature
and direction of the curve are set by dragging the
mouse at each vertex.
Keyboard Entry rollout
Keyboard entry for lines is different from keyboard
entry for other splines. Entering keyboard values
cont inues to add vertices to the existing line until
you click Close or Finish.
Add Point—Adds a new point to the line at the
current X /Y/Z coordinates.
Clo se—Closes the shape, adding a final spline
segment between the m ost recent vertex and the
first.
Fin ish —Finishes the spline without closing it.

Use Rectangle to create square and rectangular
splines.
Examples of rectangles
Procedure
To create a rectangle:
1.
Go to the Create p anel and choose
Shapes.
2. Click Rectangle.
3. Chooseacreationmethod.
4. Drag in a viewport to create a rectangle.
Optionally, press
Ct rl while dragging to
constrain the spline t
oasquare.

See Splines (page 1–266) for an explanation of
these parameters.
