struct Strand

How one line of a multiline runs along a segment: where its pieces lie and where its fill lies.

Field	Type	Meaning
`Spans`	`std::vector<double>`	The parameters of the line's pieces along the segment; group 74 counts them. Group 41.
`Fills`	`std::vector<double>`	The parameters of the line's area fill; group 75 counts them. Group 42.

A vertex of a multiline, with the segment that starts at it.

Field	Type	Meaning
`Position`	`Vector`	The vertex, in world coordinates. Groups 11, 21, 31.
`Direction`	`Vector`	The direction of the segment that starts at the vertex. Groups 12, 22, 32.
`Miter`	`Vector`	The direction of the miter at the vertex. Groups 13, 23, 33.
`Strands`	`std::vector<Strand>`	How each line of the style runs along the segment, in the style's order.

The AcDbMline subclass of an MLINE: its style, its justification and its vertices.

Field	Type and default	Meaning
`Style`	`Symbol`	The name of the multiline style. Group 2.
`Styled`	`Handle`	The MLINESTYLE object. Group 340.
`Scale`	`double{1}`	The scale of the style's offsets. Group 40.
`Justification`	`int`	0 top, 1 zero, 2 bottom. Group 70.
`Flags`	`int`	1 has vertices, 2 closed, 4 start caps suppressed, 8 end caps suppressed. Group 71.
`Lines`	`int`	The number of lines in the style. Group 73.
`Start`	`Vector`	The start point, in world coordinates. Groups 10, 20, 30.
`Normal`	`Vector{Up}`	The normal of the plane the entity is drawn in. Groups 210, 220, 230.
`Joints`	`std::vector<Joint>`	The vertices; group 72 counts them.

An MLINE: several parallel lines drawn together, as a multiline style sets them.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Web`	`Boxed<Entities::Web>`	The style, justification and vertices, from the AcDbMline subclass.
