Entity/Object	Variable	Description
integer		Version.
integer	type	Object type: 0 for a point object, 1 for a curve object, 2 for a solid object, and -1 for a mixed object.
Boolean		1 if void regions are labeled; 0 otherwise.
double		Relative geometry tolerance.
integer	nv	Number of vertices.
double[nv]	vtx	Vector of vertex coordinates.
integer[nv][2]	ud	Matrix of integers giving domains on upside and downside of each vertex.
integer	na	Number of attributes.
Attributes[na]		Attributes. The Attribute type is undocumented because it is only used internally.

Description

The Geom1 type represents a geometry object in 1D that is not an assembly. The geometry object must not be self-intersecting.
