Spline

A spline is a continuous curve that runs through numerous fit points. To draw a Spline see the Spline Tool

Spline

The spline entity consists of the following data in addition to the Common Data:

Property Name	Data Type	Description
Center Point	3D Point (X, Y, Z coordinates)	The coordinates of the very center of this entity. Used to relocate the entity as a whole.
Start Tangent	Scientific Data	The angle at which the curve starts.
End Tangent	Scientific Data	The angle at which the curve ends.
Length	Scientific Data	The total length of the spline curve.

The above properties are shown in the Selection Property Tree when a spline is selected using Selection Tool. Currently a spline's vertices are not available in property tree for editing, but vertices can be edited using the grip points at each vertex on the drawing screen.
