struct Measure

The AcDbDimension subclass every kind of dimension shares: its block, its text and the plane it is drawn in.

Field	Type and default	Meaning
`Version`	`int`	The version of the dimension's layout. Group 280, from R2010.
`Block`	`Symbol`	The name of the anonymous block that draws the dimension. Group 2.
`Point`	`Vector`	The definition point, in world coordinates; what it marks depends on the kind. Groups 10, 20, 30.
`Middle`	`Vector`	The middle of the text, in the entity's own coordinate system. Groups 11, 21, 31.
`Clone`	`std::optional<Vector>`	Where clones of a baseline or continued dimension are inserted, in the entity's own coordinate system. Groups 12, 22, 32.
`Flags`	`int`	The kind in the low three bits: 0 rotated, 1 aligned, 2 angular, 3 diameter, 4 radius, 5 three-point angular, 6 ordinate; then 32 block of this dimension alone, 64 ordinate of X, 128 text moved by the user. Group 70. A DIMENSION writes the low three bits from its form.
`Text`	`std::string`	The text the user gave, where <> stands for the measurement; empty shows the measurement, a space nothing. Group 1.
`Attachment`	`int{MiddleCenter}`	The attachment point of the text, as an MTEXT's: 1 top left to 9 bottom right. Group 71, from R2000.
`Spacing`	`std::optional<int>`	The line spacing style of the text: 1 at least, 2 exactly. Group 72, from R2000.
`Factor`	`std::optional<double>`	The line spacing of the text, as a factor of the default. Group 41, from R2000.
`Measured`	`double{Unmeasured}`	The measurement, as AutoCAD last computed it. Group 42, from R2000.
`Above`	`int`	A flag DXF does not document. Group 73, from R2007.
`First`	`int`	Whether the first arrowhead is flipped. Group 74, from R2007.
`Second`	`int`	Whether the second arrowhead is flipped. Group 75, from R2007.
`Oblique`	`std::optional<double>`	The oblique angle of the extension lines of a linear dimension. Group 52.
`Rotation`	`std::optional<double>`	The rotation of the text away from its default direction. Group 53.
`Turned`	`std::optional<double>`	The rotation of the block that draws the dimension. Group 54.
`Horizontal`	`std::optional<double>`	The horizontal direction of the text and lines: minus the angle from the OCS X axis to the UCS X axis. Group 51.
`Normal`	`Vector{Up}`	The normal of the plane the entity is drawn in. Groups 210, 220, 230.
`Style`	`Symbol`	The name of the dimension style. Group 3.

Constants

`MiddleCenter`	`int = 5`	The attachment point a new dimension's text takes: 5, middle center, as an MTEXT's group 71 names it.
`Unmeasured`	`double = -1`	The measurement of a dimension not yet measured.
