The new BIMuk Standard.STB simplifies Plot Styles to the minimum with only five Basic plot styles. With the introduction of the Line weight property for AutoCAD Layers and Entities the need to define this at the Plot style level has been negated. The original thinking behind plot styles was to have a plot style defined for each pen such as fine, medium, thick etc…. As many or as few plot styles can be defined as required within the Plot Style Table. Instead a name is defined such as “Fine” and then different plot settings such as Lineweights, Linetypes, fill patterns etc are applied to it. Each Forest may determine their own unique Plot Style Table file (.ctb) and line weights. Named Plot styles make no reference to the AutoCAD color. preparation of consistent and compatible AutoCAD files. Stbs contain Named Plot Styles which can be defined be the User. Primarily for use with A1 to A3 reduction. Screening for Pens 1 to 249 is at 100% and Pens 250 to 255 is set to 50%. All pens print black.įor Colour printing use True Colour or Colour book options. Colours 10 to 255 as per Tri Services standard.

These are based upon the pen colour mappings shown on the Pen Weights Section. The first 9 colours are based upon the ISO draughting Pen colours and the other 247 colours used a matrix to determine the pen thickness.īIMuk have produced the following AutoCAD CTB files that may be used with this standard. With the introduction of True Color and the Color books the use of all 256 colors for black has been adopted in various standards and is the basis for the BIMuk Colour based plot Style. General CAD practice was originally to use the first 8 colors as Black and then use the other colr assignments for Color plotting. The majority of users still plot using Ctb based plotting as this is the traditional method of plotting and most AutoCAD standards are therefore built around this
By understanding the two systems it is possible to produce data that will replicate perfectly in both systems.

Most CAD software plots either using a colour based plotting system where a color represents a specific pen weight or alternatively a plot style base where colour and lineweight are independent.
