Bevel Notes in Drawings

It is possible to add symbolic information about the beveling in a standardized format, so called bevel notes. This can be done in the following cases:

• Along joints (seams, outer contours) in plane views of plates.

• Ditto along the edges of brackets.

• Along traces of stiffeners in symbolic drawings.

• Along the trace and edges of the endcuts in planar views of stiffeners.

The bevel notes are made in accordance with international standards, for example, ISO 4063 and (especially) DIN 1912, Part 5, which to a large extent are covered in those parts relevant in shipbuilding. for further information, see these standards.

The constituents of a bevel note are:

• An arrow line with an arrow.

  In joints with differences in complexity of the bevels on both sides of the joint, the arrow should point to the most complex bevel.

• One or two reference lines, connected to the arrow line.

  One line is solid, the other dashed.

  In quite symmetric bevels there is only one (solid) reference line. Otherwise, the relative position of the two reference lines indicate the orientation of the bevel.

  If the upper line is solid the positive side of the bevel is upwards in the drawing (that means, facing you). If the upper line is dashed the negative side of the bevel is turned upwards.

  On and below the reference lines the bevel note may contain texts and symbols as described in more detail below

• The text on and below the reference line(s) is derived from the bevel type/variant and is customer defined by the DRAW_TEXT and BEFORE_SYMB_TEXT statements, see above.

  The text to the left of the bevel symbol is valid for the bevel on the side of the joint, pointed to by the reference arrow. Text may occur both above and below the reference lines.

• The symbols may be used to indicate the bevel type, the welding,

  The symbols are selected from a special symbol font with number 90. The standard contents of that symbol font are shown below in Symbol Font for Bevel Handling.

• In case there is a special weld process text defined (by the WELD_PROCESS_TEXT statement) the bevel note may optionally contain a trailing such text. This text will be preceded by a "fork", connected to the reference line.

Let us introduce the following abbreviations:

When, in case of an asymmetric butt joint, there is a need for individual texts/symbols, let capital letters of the abbreviations above be used for information related to the side of the joint, pointed at by the arrow.

Any of the constituents in the specification below may, of course, be empty.

In case of a symmetrical butt joint and in case of fillet joints the most complicated layout of a bevel note may become as in the figure below

Figure 1:60. Bevel note for a symmetrical joint, most general care.

If none of the texts are split into upper and lower parts the note will become simplified as shown by the next figure

Figure 1:61. Bevel note for symmetrical joint, no "under line" text.

The most complex layout of a bevel note for an asymmetric joint would have the following layout

Some typical examples of bevel notes are shown in the pictures below. (However, none of them contain any text below the reference line, any 'after text' symbol nor any 'weld processing text'.)
