Spline Tool

Use the Spline tool to connect two nodes with a three-dimensional spline curve.

The Spline tool is only available in the  Top view tool or  Side view tool is enabled.

Click with the left mouse button on a node to make this node the starting point of the connection. Left-clicking on another node determines the ending point of the connection. TuMan will calculate the spline curve between these nodes considering other connections to the specified nodes. The new spline curve is a segment of the tunnel axis. See Cross-Section to assign a cross-section geometry to the segment.

Note: A node can not have more than two connections to other nodes.
