This information applies for setting up geometry data import both for direct import when running within Autocad/Intellicad and when importing data from a DXF file.

** 3D FACEs **

3dfaces will be split to two triangular polygons if not planar.

** Extruded and Flat 2D SOLIDs **

Solids will appear as a single polygon or as a box if the
thickness is not zero.

** Extruded and Flat TRACEs **

Traces will appear as a single polygon or as a box if the
thickness is not zero.

** Extruded 2D-PLINEs **

2d-polylines with a thickness different from zero will appear
as a set of polygons. With R14, this includes lightweight
polylines.

** Wide 2D-PLINEs **

2d-polylines with a starting width different from zero set in
their header entity (not the vertexes!) will appear as a
polygon following the trace of the polyline with a constant
width. This option will override the one below for poly-
lines that match both categories.
Together with a thickness and the respective option set this
will will result in a kind of a quadrilateral worm. With R14,
this includes lightweight polylines.

** Closed 2d-PLINES as Polygons**

2d-polylines with the closed flag set in their header entity
will appear as a polygon of the shape of the polyline.
polylines with a width will not follow this rule if the
option above is chosen as well (Wide 2d-plines).
Together with a thickness and the respective option set this
will result in a prismatic volume of the shape of the polyline.

This option is off by default.

** 3D-MESHes **

The Faces of 3d-polygon meshes will appear as a set of
polygons ignoring spline fits of any kind. Nonplanar faces
will be split into two triangles.

** POLYFACEs **

The faces of polyface meshes will
appear as a set of polygons. Nonplanar faces will be split
into two triangles.

** Extruded LINEs **

Lines with a thickness different from zero will appear as a
single polygon.

** Extruded ARCs **

Arcs with a thickness different from zero will be segmented
according to the given arc tolerance.

** Extruded and Flat CIRCLEs **

Circles will appear as a ring with a inner radius of zero
or as a cylinder/tube with a ring at either end if their
thickness is different from zero.

** POINTs as Spheres **

Point entities will appear as spheres or bubbles depending on
either their thickness (if any) or else on the value of the
DXF variable "PDSIZE". if the result is zero
the entity is ignored.

This option is off by default.

** ACIS 3D Solids **

ACIS solids are topologically closed volumes in boundary
representation,
and will be converted to sets of triangle polygons.

This selection is only available when importing
directly from Autocad 2000.

** ACIS Bodies **

Bodies are partial 3d solids, which may be topologically
open.

This selection is only available when importing
directly from Autocad 2000.

** ACIS 2D Regions **

Regions are planar entities that can be manipulated per
boolean operations,
and will be converted to sets of triangle polygons.

This selection is only available when importing
directly from Autocad 2000.
