ACI
:ref:`ACI`
ACIS
The 3D ACIS Modeler (`ACIS`_) is a geometric modeling kernel developed
by `Spatial Corp.`_ ® (formerly `Spatial Technology`) and now part of
`Dassault Systems`. All ACIS based DXF entities store their geometry as
:term:`SAT` or :term:`SAB` data. These are not open data formats and
a license has to be purchased to get access to their SDK, therefore
`ezdxf` can not provide any support for creating, processing or transforming
of ACIS based DXF entities.
bulge
The :ref:`bulge value` is used to create arc shaped line segments in
:class:`~ezdxf.entities.Polyline` and :class:`~ezdxf.entities.LWPolyline`
entities.
CAD
Computer-Assisted Drafting or Computer-Aided Design
CTB
Color dependent plot style table (:class:`~ezdxf.acadctb.ColorDependentPlotStyles`)
DWG
Proprietary file format of `AutoCAD`_ ®. Documentation for this format
is available from the Open Design Alliance (`ODA`_) at their `Downloads`_
section. This documentation is created by reverse engineering therefore
not perfect nor complete.
DXF
Drawing eXchange Format is a file format used by `AutoCAD`_ ® to
interchange data with other :term:`CAD` applications. `DXF`_ is a
trademark of `Autodesk`_ ®. See also :ref:`what is dxf`
proxy-graphic
The proxy-graphic is an internal data format to add a graphical
representation to DXF entities which are unknown (custom DXF entities),
not documented or very complex so CAD applications can display them
without knowledge about the internal structure of these entities.
raw-color
Raw color value as stored in DWG files, this integer value can
represent :term:`ACI` values as well as and :term:`true-color` values
reliable CAD application
CAD applications which create valid DXF documents in the meaning and
interpretation of `Autodesk`_. See also :ref:`what is dxf`
SAB
ACIS file format (Standard ACIS Binary), binary stored data
SAT
ACIS file format (Standard ACIS Text), data stored as ASCII text
STB
Named plot style table (:class:`~ezdxf.acadctb.NamedPlotStyles`)
true-color
RGB color representation, a combination red, green and blue values to
define a color.
