In writing DXF when lines are output I use autocad_width and autocad_linetype in combination with a DXF Template file in order to get the desired output styling for 2D lines.

For 3D lines this doesn't work and 3D lines are output in some default manner.

As I am not an expert with DXF/DWG and only create such files with FME could somebody help me out with the following questions:

• Is it possible to style 3D lines in any way ? Thickness, dashed, etc.
• If NOT: what do people usually do if 2D and 3D lines are coexistent and should be combined in the same output file, while the 2D visual appearance matters and should be used also for 3D lines?

At the moment the only way to cope with 3D styling deficiencies seems to be

1. double 3D line layers, in order to have a 2D and seperate 3D copy
2. force one layer to 2D and style it as usual
3. output the redundant 3D layer as is in order to keep the 3D information

Thanks for any help
