Vector lists require the following parameters, typically formatted as follows:

NumVertices<nl>
[VertexX<spc>VertexY<spc>VertexZ<spc>MoveDrawFlag<nl>
[...]]

where NumVertices is an integer defining the number of vertices making up the vector list, VertexX is a double defining a local X co-ordinate for a vertex, VertexY is a double defining a local Y co-ordinate for a vertex, VertexZ is a double defining a local Z co-ordinate for a vertex, MoveDrawFlag is an integer indicating whether a straight line should be drawn from the previous vertex to the current vertex (1) or not (0), <spc> is the space character and <nl> is the newline sequence.

Each vector list, analogous to a Polyline in AutoCAD, is made up of a number of vertices linked by straight lines.

Each vertex is defined as a point made up of an X, Y and Z co-ordinate and a move-draw flag. The MoveDrawFlag of the first vertex must be 0 (move). The number of vertices defined must match the value of the NumVerticesparameter.

For example, the following defines the parameters for a vector list that appears as a square:

5
0.0 0.0 0.0 0
1.0 0.0 0.0 1
1.0 1.0 0.0 1
0.0 1.0 0.0 1
0.0 0.0 0.0 1

All vertex co-ordinates are relative to the vector list's local axes.
