Make Solid From Sections

This command creates a solid model using cross sections and a centerline alignment. For example, tunnel cross sections can be used for this method.

The cross sections can be prepared with the Create Sections routines in the Solid menu. There are also routines to prepare the centerline file in the Solid menu.

The settings dialog has an option to Merge With Existing Solid for merging the solid model for the new cross section data with an existing solid model. This option applies to combining data for intersection tunnels. The Merge Tolerance is the distance for replacing the previous solid model data points with the new data points.

To build the solid model, the program connects the data between the cross section stations and caps the solid model at the ends.
