A layer control file could look like the example below. Note that in this example there are 4 different entries for stiffener, allowing separate layers for stiffeners with different combinations of color line type and thickness. Up to 20 entries for each model type are allowed.

PROFILES	PROF4	24	SHORTDASH	THIN
PLATES	PLAT1	0	SOLID	THIN
STIFFENERS	STIF1	0	SOLID	THIN
STIFFENERS	STIF2	24	DASHDOT	XWIDE
STIFFENERS	STIF3	24	SOLID	WIDE
STIFFENERS	STIF4	24	DASHED	THIN
MEASURES	MEAS1	24	ALL	THIN

FLANGES	FLANG	ALL	ALL	ALL
BRACKETS	BRA	0	SOLID	THIN

CUTOUTS	CUT1	ALL	SOLID	THIN

This example is also available as a file for copy and further use: Drafting_dxf_layer_ctrl.txt

The valid color codes and corresponding color are as below:

ALL	Any color
0	GREEN
1	BLACK
6	CYAN
12	BLUE
18	MAGENTA
24	RED

2	WHEAT
3	MEDIUMAQUAMARINE
4	NAVYBLUE
5	DARKORCHID
7	FIREBRICK
8	ORANGE
9	FORESTGREEN
10	DIMGREY

The key word of valid line types as below, corresponding to basic linetypes

ALL	Any line type
SOLID	Solid line
DASHED	Dashed line
DASHDOT	Dashed and dotted line
DASHDOT2	Dashed and double dotted line
SHORTDASH	Short dashed line
DASHSOLID	Dashed and solid in parallel
TRACK	Track line

The valid thickness codes as below:

ALL	Any thickness
THIN	Thin line
WIDE	Wide line
XWIDE	Extra wide line

The syntax rules for the file are as follows:

Each line should consist of two strings separated by one or more blank spaces. The first string is a keyword string for the model or annotation element. The first 4 letters are significant. The second string is the user defined layer name, which should have alphanumerical characters. The layer names must be unique.
