Add Resource Table Entries
==========================
All resources require a unique name in their category (names are case-insensitive).
Layer
-----
A layer in a DXF document is a category that controls visual properties (like color and
linetype) for associated entities. It acts like a grouping tag, not a container.
Add a new layer to a DXF document::
doc.layers.add("MY_NEW_LAYER", color=1, linetype="DASHED")
DXF entities reference layers, but layers themselves don't directly contain entities.
Instead, each entity has a :attr:`dxf.layer` attribute that specifies the layer by name
it belongs to.
- :meth:`ezdxf.sections.table.LayerTable.add`
Linetype
--------
The linetype defines the rendering pattern of linear graphical entities like LINE, ARC,
CIRCLE and so on.
Add a new linetype to a DXF document::
doc.linetypes.add("DOTTED", pattern=[0.2, 0.0, -0.2])
- :meth:`ezdxf.sections.table.LinetypeTable.add`
Text Style
----------
The text style defines the rendering font for text based entities like TEXT, ATTRIB and
MTEXT.
Add a new text style to a DXF document::
doc.styles.add("ARIAL", font="arial.ttf")
- :meth:`ezdxf.sections.table.TextstyleTable.add`
Dimension Style
---------------
The dimension style defines the initial properties for the DIMENSION entity.
Add a new dimension style to a DXF document::
doc.dimstyles.add("EZDXF")
- :meth:`ezdxf.sections.table.DimStyleTable.add`
AppID
-----
The XDATA section of DXF entities is grouped by AppIDs and these ids require an entry in
the :class:`AppIDTable` otherwise the DXF file in invalid (for AutoCAD)::
doc.appids.add("EZDXF")
- :meth:`ezdxf.sections.table.AppIDTable.add`
