Detailed Description

DXF definition of an AutoCAD mline entity.

Warning:: The 2 group codes in mline entities and mlinestyle objects are redundant fields.
These groups should not be modified under any circumstances, although it is safe to read them and use their values.
The correct fields to modify are:
Mline: The 340 group in the same object, which indicates the proper MLINESTYLE object.
Mlinestyle: The 3 group value in the MLINESTYLE dictionary, which precedes the 350 group that has the handle or entity name of the current MLINESTYLE.
