<set_name>

Is a name that uniquely identifies a certain rule for placement of the face plate (<= 8 characters).

PROF_SET

Specifies the name of the set of profile dimensions that shall be used when picking the profile. This set must previously have been defined in a PROFILE statement.

MIN_LENGTH

Normally a face plate shorter than MIN_LENGTH will not be accepted (unless explicitly asked for by the user). Default value is 700 mm.

END1_CUT

Defines the endcut (type and parameters according to standards) for end 1 of the face plate (close to arm A of the bracket).

An endcut parameter >10000 (for example, a toe height) will be interpreted in the following way, suppose 1xxxx.y. Here, xxxx is a maximum value and 0.y is factor to be multiplied by the profile height/width.

Example:

Suppose that a normal endcut for a free flange has been defined by /END1_CUT=(1402, 10060.3) and that the width of the face plate is 180 mm. The parameter (toe height) will then be assigned the value 0.3*180= 54 mm. If, on the other hand, the profile width had been 250 mm the toe width would have been 60 mm since 0.3*250=75 (which is greater than 60).

END1_DIST

Distance from end 1 of the face plate to the end of the free side along the bracket contour (close to arm A of the bracket), see figure below.

Figure 5:18. Free distance of welded flange.

END2_CUT

Ditto for end 2 of the face plate.

END2_DIST

PATTERN

Defines the name of the pattern that should be applied for the flange. The patterns referred to must have been defined before in a PATTERN statement.

Several patterns can be defined to be selected depending on the depth of the bracket (denoted Z). The first pattern ( <pt1 > ) will be used when Z <= <size1 >,

(This means for example, that a given bracket may have no profile at all up to certain size, then in the next size interval have a stiffener set parallel to the free edge, and finally in another size interval have a welded flange).

If a certain pattern is set to ' ' (an empty string) this means that in the corresponding size interval there should not be any face plate at all.

SIZE_LIM

Cf. PATTERN. The values should always be given in increasing order.

The SIZE_LIM attribute must come after the PATTERN attribute in sequence.

If the number of values assigned to PATTERN is N, then the number of values assigned to SIZE_LIM must be N-1.

OVER_SHOOT

A face plate is normally placed symmetrically relative to the plate surface of the bracket. The attribute OVER_SHOOT can be used to control that the face plate should be placed asymmetrically.

The distance given is the offset outside the mould plane of the bracket in the direction opposite to the "positive profile side" (defined by PSID in the generation).

A face plate with an offset will be stored as a stiffener, whereas symmetrical face plates are stored as flanges.
