In DxfIO::Entities

struct Geometry

The AcDbModelerGeometry subclass: the ACIS body of a solid, a region or a surface.

Field	Type	Meaning
`Version`	`std::optional<int>`	The version of the modeler's format. Group 70.
`Lines`	`std::vector<Group>`	The lines of the ACIS body, as DXF encodes them, kept as groups; empty when the body is in ACDSDATA. Groups 1 and 3.
`Stored`	`std::optional<bool>`	A flag of the R2013 layout, which DXF does not document. Group 290.
`Guid`	`std::optional<std::string>`	The GUID of the body, in the R2013 layout. Group 2.

A REGION: a closed flat area, kept as an ACIS body.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Picture`	`std::string`	The proxy graphics, for programs that cannot draw the entity. Group 92, or 160 from R2010, then 310.
`Geometry`	`Boxed<Entities::Geometry>`	The ACIS body, from the AcDbModelerGeometry subclass.

A BODY: an ACIS body that is neither a solid nor a region.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Picture`	`std::string`	The proxy graphics, for programs that cannot draw the entity. Group 92, or 160 from R2010, then 310.
`Geometry`	`Boxed<Entities::Geometry>`	The ACIS body, from the AcDbModelerGeometry subclass.

A 3DSOLID: a solid, kept as an ACIS body.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Picture`	`std::string`	The proxy graphics, for programs that cannot draw the entity. Group 92, or 160 from R2010, then 310.
`Geometry`	`Boxed<Entities::Geometry>`	The ACIS body, from the AcDbModelerGeometry subclass.
`History`	`Handle`	The history of how the solid was made. Group 350, from R2007.

template <Sheet KindV>

A surface entity of the kind given: its ACIS body, the isolines drawn on it, and the kind's own groups.

Field	Type and default	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Picture`	`std::string`	The proxy graphics, for programs that cannot draw the entity. Group 92, or 160 from R2010, then 310.
`Geometry`	`Boxed<Entities::Geometry>`	The ACIS body, from the AcDbModelerGeometry subclass.
`Across`	`int{6}`	The number of isolines drawn across the surface along U. Group 71.
`Along`	`int{6}`	The number of isolines drawn across the surface along V. Group 72.
`Tail`	`std::vector<Group>`	The groups that follow the isolines, the kind's own data, kept as they came.

The kinds of surface entity.

A SURFACE: a surface of no more particular kind.

using Surface = SurfaceOf<Sheet::Plain>;

A PLANESURFACE: a flat surface.

using PlaneSurface = SurfaceOf<Sheet::Planar>;

A NURBSURFACE: a surface shaped by NURBS control vertices.

using NurbSurface = SurfaceOf<Sheet::Nurbs>;

An EXTRUDEDSURFACE: a profile extruded along a direction.

using ExtrudedSurface = SurfaceOf<Sheet::Extruded>;

A LOFTEDSURFACE: a surface through several cross sections.

using LoftedSurface = SurfaceOf<Sheet::Lofted>;

A REVOLVEDSURFACE: a profile turned about an axis.

using RevolvedSurface = SurfaceOf<Sheet::Revolved>;

A SWEPTSURFACE: a profile swept along a path.

using SweptSurface = SurfaceOf<Sheet::Swept>;
