struct PolylinePOLYLINE

A POLYLINE: a 2D or 3D polyline, a polygon mesh or a polyface mesh, its vertices following it in the file.

Field	Type and default	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Follows`	`bool{true}`	Whether VERTEX entities follow it in the file. Group 66.
`Position`	`Vector`	A point whose Z is the polyline's elevation; its X and Y are 0. Groups 10, 20, 30.
`Thickness`	`double`	How far the entity is extruded along its normal. Group 39.
`Flags`	`int`	1 closed, 2 curve-fit, 4 spline-fit, 8 3D polyline, 16 polygon mesh, 32 mesh closed along N, 64 polyface mesh, 128 linetype drawn continuously around the vertices. Group 70.
`Start`	`double`	The width segments start with when their vertex gives none. Group 40.
`End`	`double`	The width segments end with when their vertex gives none. Group 41.
`Rows`	`int`	The vertex count along M of a polygon mesh, or the vertex count of a polyface mesh. Group 71.
`Columns`	`int`	The vertex count along N of a polygon mesh, or the face count of a polyface mesh. Group 72.
`Density`	`int`	The density along M of a smoothed polygon mesh. Group 73.
`Depth`	`int`	The density along N of a smoothed polygon mesh. Group 74.
`Curve`	`int`	How the surface is smoothed: 0 not at all, 5 quadratic B-spline, 6 cubic B-spline, 8 Bezier. Group 75.
`Extrusion`	`Vector{Up}`	The normal of the plane the entity is drawn in. Groups 210, 220, 230.
`Vertices`	`Sequence<Vertex>`	The vertices that follow it in the file, closed by a SEQEND.
