Spline Append
In: Spline & Path Tools > Spline Tools
Description
Splines are packaged as a list. This node appends a list of input splines (set #2) onto an existing list (set #1).
The order of the lists is preserved, meaning appending a list D-E-F onto a list A-B-C results in a list A-B-C-D-E-F.
TIP
Be mindful of the order in which you append splines, as this order is taken into account in other nodes, such as Scatter on Splines, the Spline Bridge nodes, etc.

Spline Amount Integer
The number of output splines.
Parameters
Flip Spline #1 Direction Boolean
Inverts the direction of the splines in the first set.
Flip Spline #2 Direction Boolean
Inverts the direction of the splines in the second set.
Preview
Segments Amount Integer
Adjusts the number of segments used to draw the spline visualization in the Preview output. A higher value results in a smoother line.
Show Direction Helper Boolean
Displays a dot at the start of the spline and an arrowhead at its end in the Preview output.
Show Thickness Envelope Boolean
Displays additional lines at the edges of the spline’s thickness.
Thickness (px) Float
Adjusts the thickness of the spline visualization in pixels in the Preview output.
