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`
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.
