Creating Line Patterns

The default Diagrams.lin file with DWG patterns definitions is placed in the %PDMSEXE% directory. This is a text file, so it can be edited using a text editor like Notepad. This file can be exchanged with another line pattern file directly in the operating system. It is possible to have project-specific patterns. To achieve this the modified Diagrams.lin file should be placed in the Diagrams sub-directory in the location pointed out by %<PROJ_ID>DFLTS%. The systems is searching for the patterns file in the following order:

1. %<PROJ_ID>DFLTS%/Diagrams

2. %PDMSDFLTS%

3. %PDMSEXE%

One pattern consists of two lines. The first line contains the name and description and uses the following syntax:

*name,description

The Second line starts with A,. It indicates the beginning of the linetype pattern:

A,pattern

A simple pattern is a sequence of dashes, dots or spaces separated by commas:

• Dash - is represented by a positive number.

• Space - is represented by negative number.

• Dot - is represented by zero.
