Overview
This feature lets you draw a Spline in the scene, which is required in various other Prespective features.
...
Example of a Spline with three conrol points.
...
Where to Find
The Spline can be found under Utilities > Create
...
By default, a Spline with two control points will be created in the scene.

Spline Specs | |
|---|---|
Close Spline | Makes the Spline closed-loop, leave unchecked for end-to-end |
Spline Length | Displays the current Spline Length in meters |
Spline Control Points | |
Auto-name Control Points | Automatically renames control points from 1 to n (where n is the number of points) if their order in the Hierarchy has changed |
Add Control Points | Adds more control points to the Spline. New Control Points are added after the last Point of the Spline. |
Spline segments | Define the default segment settings for new segments that are created |
Default segment Color | Changes the color of a default segment in the scene |
Default segment tesselation mode | The type of default tesselation (samples per unit of length or samples per percentage of length) |
Default tesselation samples | The default amount of samples used for tessellation |
#0: ‘Point[1]' → 'Point[2]’= 0.999999m | |
Segment Color | Changes the color of this segment in the scene |
segment tesselation mode | The type of tesselation to use for this segment (samples per unit of length or samples per percentage of length) |
segment tesselation samples | The amount of samples used for tessellation for this segment |
Scene View Settings | |
Control Point Label Mode | Defines the type of labels used for the control points. (none, name only, full info) |
Control Point Label Text Color | Changes the color of a spline segment in the scene |
Show Spline Normal Line | Whether or not to show the (green) normal line that describes the normal for every point on the spline |
Show When not Selected | Whether or not show the Spline when it is currently not selected in the hierarchy |
...
Conrtol Point Vector | |
|---|---|
Handle Type | NONE: No handles and therefore no curvature IN_ONLY: A handle for in-direction tangency. Adds curvature in the direction of the previous control point OUT_ONLY: A handle for out-direction tangency. Adds curvature in the direction of the next control point CONTINUOUS: A handle for in-, and out-direction tangency. Adds curvature through this control point in the direction of both the previous- and next control point, with the out-direction handle being the inverse of the in-direction handle BROKEN: A handle for in-, and out-direction tangency. Adds curvature through this control point in the direction of both the previous- and next control point, with both handles individually definable |
Handle Space | Sets the space (LOCAL or GLOBAL) in which to set the handle |
Control Point Handle Limits | |
Use Handle Limits | Constrains the handles to a single plane |
Handle Limit Space | Sets the space (LOCAL or GLOBAL) in which to set the handle limit plane |
Handle Limit Plane | Sets the up-direction of the constraining plane |
Control Points Up Direction | |
Up direction rotation | Sets the rotation (in degrees) of the control point normal relative to the match up direction |
Match up direction | Sets the direction relative to which the control point normal is set SPLINE_VECTOR WORLD_DIRECTION LOCAL_DIRECTION |
up Match direction | The axis relative to which the spline normal is rotated |
Sceneview Settings | |
show Normal X axis | Show the Normal X axis of the control point normal |
show Normal Y axis | Show the Normal Y axis of the control point normal |
show Normal Z axis | Show the Normal Z axis of the control point normal |
show Gizmo when not in Selection | Show the control point gizmo when the point is not selected in the hierarchy |
Normal Display Modifier | The distance in units from the spline to the spline normal |
...
How to use
To change the shape of the spline, select one (or more) control points in the scene by dragging a box around them using your cursor, or by directly selecting them in the Hierarchy. You can now move the points like any other object in the scene.
