Use Angle to create a closed “L” shaped spline. You have the option to specify the radii of the corners between the vertical and horizontal legs of the section.

Example of Angle
Procedures
To create an Angle spline:
- Go to the
Create panel and turn on
(Shapes).
- Open the Shapes List and select Extended Splines.
- Click Angle.
- Drag and release the mouse button to define the initial size of the angle.
- Move the mouse and then click to define the thickness of the walls of the angle.
Interface
Rendering and Interpolation rollouts
Most spline-based shapes share these parameters. For details, see Rendering rollout and Interpolation rollout.
Creation Method rollout
The Angle shape offers the standard creation-method choice: Center or Edge. For details, see Creation Method rollout.
Keyboard Entry rollout
Creates an Angle spline from the keyboard. Use the X/Y/Z settings to specify the center point, and the remaining parameters to specify the dimensions, then click Create. After creating the spline, you can use the Parameters rollout controls to adjust its settings (see following).
Parameters rollout

- Length
-
The height of the vertical leg of the angle.
- Width
-
The width of the horizontal leg of the angle.
- Thickness
-
The thickness of both legs of the angle.
- Sync Corner Fillets
-
When on, Corner Radius 1 controls the radius of both the interior and exterior corners between the vertical and horizontal legs. It also maintains the thickness of the section. Default=on.
- Corner Radius 1
-
The exterior radius between the vertical and horizontal legs of the angle.
- Corner Radius 2
-
The interior radius between the vertical and horizontal legs of the angle.
- Edge Radii
-
The interior radius at the outermost edges of the vertical and horizontal legs.
Note: Take care when adjusting these settings. There are no constraining relationships between them. Therefore, it's possible to set an inside radius (Corner Radius 2) that is greater than the length or width of the legs of the angle.
