Vectorworks Tip 408 – DXF/DWG – Line Weights.

Older versions of AutoCAD did not carry line weight information and they used to use colours to represent line weights for printing. Some users of AutoCAD still use colours to represent line weights. When you imported DXF/DWG file you can specify which colours are equal to its line weights. Vectorworks uses line weights directly without reference to colours to this technique can convert the objects to the correct line weights.
