The wall spline is a timber and pile wall as used for small docks.
The wall is designed to be 4 metres above ground level, with 3 metres below, but can be raised to any level to suit. It may be bent to a suitable shape.
Use the shift key to prevent splines joining to previously placed ones. Alternate files are provided to eliminate the green texture - see the Readme file included.
Once installed you will find it as Dock Timber Wall under splines in the Australia listing.
