Type Standard Brackets, Explicitly Defined
- Last UpdatedDec 08, 2025
- 2 minute read
This syntax is used explicitly to define all necessary information about the bracket, its geometry and its position.
Currently, this syntax can be used mainly for simple types of brackets.
Syntax:
|
BRA, <bkt_definition> [,<symmetry>] ,MAT= <plate_thickn> ,MSID= <side_info> , <bkt_param> [,PSID= <side_info>] [,PQUAL= <quality>::= <quality_code>|<quality_string>] [,DOUBLE] [, <profile_size>] , <position> [,POS= <pos_no>] [,QUA= <quality_code>] [,WELD= <leg_length> (1 ... 3)] [,VAR= <variant_no>] [,SEP | BEL] [,V1= <angle_1>] [,V2= <angle_2>] ; |
Most of the clauses are used in the same way as described above in the normal bracket syntax. Only the deviations will be described in detail below.
Description
|
<bkt_definition> |
MIRR and SYNTAX must not be used when selecting the bracket. |
|
MSID |
The orientation of the plate relative to the mold plane of the bracket must be defined. |
|
<side_info>::= AFT|FOR|SB|PS|TOP|BOT |
|
|
<bkt_param> |
Parameters controlling the geometry of the bracket. |
|
<bkt_param>::= (<param_keyw>=<number>)(...) |
|
|
<param_keyw>::= A|B|C|D|E|F|G|H|J|K |
|
|
<position> |
The bracket is located in space by three points assigned to ORI, UAX and VAX in the same way as described in the PANEL statement. The local uv-system of the bracket has its origin in the lower left corner of the bracket and the u-axis is along the edge A. If the point assigned to VAX lies along the edge B of the bracket, the center angle of the bracket will be calculated automatically (see V1 below). |
|
PQUAL |
defines the material quality of the bracket profiles. <quality>::= <quality_code>|<quality_string> <quality_code>::= <integer> <quality_string>::= <string> If left out entirely, the quality of the bracket will be selected. |
|
V1 |
defines the angle of the origin of the bracket. If not given, it will be calculated as the angle between the vectors from ORI to the points UAX and VAX, respectively (see <position> above). |
|
<angle_1>::= <number> |
|
|
V2 |
Relevant only for brackets with another edge at the end of edge A. The angle at this corner is assigned to V2. |
|
<angle_2>::= <number> |
|
|
Example: |
|
|
BRA, B, COR=2, MAT=12.5, A=500, B=500, MSIDE=TOP, PSID=TOP, ORI=FR75, 2000, 1000, UAX=FR75, 3000, 1000, VAX=FR76, 2000, 1000; |
