tags:: DXF-Internals
- The line cap- and join styles are not stored in the DXF entities itself!
- [[BricsCAD]] does not support the ENDCAPS and JOINSTYLE settings and always uses round caps and round join style.
- [[CTB]] files define line cap- and join styles:
- END_STYLE_BUTT = 0
- END_STYLE_SQUARE = 1
- END_STYLE_ROUND = 2
- END_STYLE_DIAMOND = 3 ???
- END_STYLE_OBJECT = 4
- JOIN_STYLE_MITER = 0
- JOIN_STYLE_BEVEL = 1
- JOIN_STYLE_ROUND = 2
- JOIN_STYLE_DIAMOND = 3 ???
- JOIN_STYLE_OBJECT = 5
- [[HEADER]] Section
- HEADER Var [[$ENDCAPS]]
- Lineweight endcaps setting for **new** objects:
- 0 = None (butt)
- 1 = Round
- 2 = Angle ???
- 3 = Square
- HEADER Var [[$JOINSTYLE]]
- Lineweight joint setting for **new** objects:
- 0 = None
- 1 = Round
- 2 = Angle (bevel or miter?)
- 3 = Flat (bevel or miter?)
