Bevels on the bracket contour

Up to four bevel attributes can be created on the bracket and another four on the related parts. Bevel attributes are only applied for connections which have been explicitly assigned to a bracket segment using a bracket keyword relation, for example BRR1. A predefined bevel will be created by default if the bevel is only defined in the W-line in the bracket type file and no keyword has been included.

One of the four bracket relation keywords can be used to specify a segment of the bracket contour to be beveled or welded. This is done by adding the bracket relation keyword to the end of an L line or a C line, see Shape definition. Adding a keyword will not be handled by adding it to the end of a P, LC, PC or CC line. These keywords can also be followed by one or two offset values. These offset values can be either absolute, written without a prefix or with a prefix of 'A' which both mark the value as absolute, or relative to the segment length, marked with a prefix of 'F'. An absolute offset will move the end of a segment the specified value in millimeters away from the end of the geometry defined in that line and a relative offset will move it as a factor of the total length of the defined segment. The first offset number is applied to the start of the segment and the second is applied from the end of the segment. If only one value is used, this is treated as the first offset. These offsets can be entered as variables or expressions. They can also be negative numbers which will move that end of the definition away from the other end, outside of the original segment.

The following example includes two segment beveling examples included. The first is defined using absolute offsets and the second is using relative offsets. This means that these two segments will have bevel attributes added, which can be modified by the user, applied only along that section of the contour. The remainder of that segment will not have a bevel attribute applied.

Q

If two or more consecutive L or C lines have the same bracket relation keywords and the offsets are defined so that there is no gap between them, then this will result in a single bevel. This means a bevel can stretch over multiple contour segments.

The bevel and weld line will follow the type file definition, even if the bevel has no connection with the related part.
