W-line in the bracket type file

Predefined Bevel numbers are specified on a separate line after the keyword 'W' in the type file, called the 'W-Line', which applies the specified predefined bevel as a bevel attribute along the entire length of a relation on a bracket. This line must be placed after the last 'M-Line' in the Bracket type file.

The system can define bevel and weld lines only if the W-Line is used. When the bevel definition is only to be applied for part of a relation then the system administrator must use the specific segment definition as well, which is discussed in Defining bevels on bracket contour segments. Variables can be used instead of numerical values in order to determine the appropriate predefined bevel for various situations within one type file.

A W-Line has the syntax of:

W 1 2 3 4 5 6 7 8

The first four numbers refer to the bevels on the bracket contour segments corresponding to the first through fourth relations and the last four numbers refer to the bevels on the related parts. This line should always contain eight integers in total which specify which predefined bevel should be applied at that particular location. If a certain relation is not defined, the corresponding numbers should be set to zero. In this example, the third and fourth relationships are not defined so they have been set as zero on both the bracket and related part. The order of the components of the W-Line correspond to locations as follows:

  • W
  • First position: predefined bevel applied to bracket along first relation
  • Second position: predefined bevel applied to bracket along second relation
  • Third position: predefined bevel applied to bracket along third relation
  • Fourth position: predefined bevel applied to bracket along fourth relation
  • Fifth position: predefined bevel applied to related part along first relation
  • Sixth position: predefined bevel applied to related part along second relation
  • Seventh position: predefined bevel applied to related part along third relation
  • Eighth position: predefined bevel applied to related part along fourth relation

An example of the use of a W-Line is provided below:

W 3 2 0 0 3 0 0 0

Using the example W-Line and image above and treating the red line as the first relation, the green line as the second relation, the brown line as the third relation and the blue line as the fourth relation, means that:

  • the bracket and the related part will both have the third predefined bevel applied along the length of the red line,
  • the bracket will have the second predefined bevel applied along the entire length of the green line but the related part will have no bevel applied along the green line and
  • neither the bracket nor the related part will have a predefined bevel applied along the length of either the brown or blue lines.
