[edit] Splines Menu

Splines are special objects that stretch between two nodes. Splines are flexible. They can bend and curve, raise above the terrain or hug the terrain closely.

The filter allows a user to reduce or increase the number of items showing in the selection window. There are two types of filter:

Content Type: Tap the filter buttons to toggle various content types on or off. This is very useful to show just the type of object that you are currently working with.
