System-Defined Line Styles

A system-defined line style is specified by combining one of ten basic line patterns (see ) with one of three line widths.
Figure 8:1. Basic User-Defined Line Patterns
The line-widths are:
|
PLOT and screen: single stroke line of minimum thickness. Other export formats: Width defined in system database, 0.25mm by default. |
|
Width defined in system database, 0.35mm by default. |
|
Width defined in system database, 0.70mm by default. |
The width definitions for THIN, MEDIUM and THICK are held in the system database for the project. They can be modified by an administrator in the ADMIN module.
Thus for example:
|
NLSTYLE LDASHED |
gives a long-dashed line of THIN width |
|
FFSTYLE SOLID |
gives a solid line of THIN width |
|
OBSTYLE DOTTEDMedium |
gives a dotted line of MEDIUM width |
|
PLSTYLE DDOTTEDMedium |
gives a double-dotted line of MEDIUM width |
|
CLSTYLE CHAINEDThick |
gives a chained line of THICK width |
|
BFSTYLE DASHEDThick |
gives a dashed line of THICK width |
Note that for minimum thickness lines the qualifier THIN is omitted.
For historical reasons an alternative set of line patterns is provided (see ).
Figure 8:2. Alternative Pre-defined Line Patterns
These alternative line-patterns can be combined with widths named WIDE and XWIDE, thus for example:
|
NLSTYLE DASHPattern |
gives an alternative dashed pattern of THIN width |
|
OBSTYLE SHORTDASHWide |
gives a short-dashed line of MEDIUM width |
|
BFSTYLE DASHDOTXWide |
gives a dash-dotted line of THICK width |
|
FFSTYLE SOLIDXWIDE |
gives a solid line of THICK width |
Note that for consistency WIDE and XWIDE can be also used with the basic pattern SOLID.
