Drawing Levels 10.3.4.1
The Draw Level text box shows the Drawing Level (DLEV) setting. This attribute restricts the elements displayed using this Style to just those that include this number in their drawing level range, as set in PDMS Design.
Every primitive in the design model has an associated drawing level range attribute.If the drawing level lies within this range, the 3D object will be drawn when it is added to the Draw List.
Assigning Colours & Styles 10.3.4.2
The Styles and Colours section of the form shows the assignment of Linestyles (Standard - which may be
‘Off’ or User-defined) and colours to the six line types i.e. Frontface, Backface, etc.
Colours can either be selected from a drop-down list (initially populated with the basic 16 system-defined colours) or selected from a colour-palette when the Pick button is clicked. The colour selector gadgets will be greyed out if the linestyle is ‘Off’.

Standard Linestyles are selected from two drop-down list gadgets. The first allows ‘Off’ or one of the 10 standard system-defined line-patterns to be selected, and the second allowing one of the three standard system-defined line-widths to be selected (Thin, Medium and Thick).
If a User-defined linestyle is required the Select button is selected to prompt the User-defined Linestyles form - the adjacent checkbox should be ticked. This will cause the two Standard linestyle gadgets to be greyed out and the User-defined Linear Styles selection form to be displayed as shown. The left-hand side of the form lists all the Linestyle Tables found in the MDB. Selecting one of these causes the right-hand side to be populated with the Table’s Linestyles, from which a selection can be made.

10.3.5 Draft Line Widths
The system defined line widths of Thin, Medium and Thick use a precise value in accordance with European
& American ISO 128 of 0.25mm, 0.35mm and 0.7mm respectively.
The definition of the Line Widths involves the use of a Line Style World (LSWL), which is visible in the PDMS Admin module:
The LSWL owns a LSWIDD element, defining a linestyle width.
Each of the LSWIDD elements has an LSWidth and LSWKey attribute.
Alternative Line Width standards can be set via the Admin module. The User can query the values from Draft by entering Q LINEWIDTHS in the Command Window.
If the default standards are being used the data returned will be:
Care needs to be taken with the precision, key in prec 2 dp to achieve the correct results.In addition, it should be noted that the widths for User Defined Linestyles are exact i.e. the precise width in mm specified be the user will be transferred directly to the export format (not applicable to Plot Files).
