Bracket type 761

Bracket type 761 is a default straight span bracket with a bird tail overlapping other construction. A small part of the bracket's dimension can be selected from a list of predefined sizes, or the user can enter the dimensions freely. If the span length is bigger than 475 mm, the system automatically adds a flange of 75 mm or 90 mm. If R1 is bigger than 699 mm, a flange of 90 mm is added, otherwise 75 mm. If the user selects a predefined size, the system gives the part a part number. Otherwise the part number will be zero.

Relation

Question

Selection criterion

First

Indicate deck

Plate or bracket in section, deck line.

Second

No question is ask the selection of the second leg is automatically don by the system.

Plate or bracket in section, hull line, profile or face plate in section, plate or bracket in plan view, profile or in plan view

If the selection criterium is a deck line, a hull line with a group other than 0 can by selected.

R variable

Default

LABEL 1

SelText[1] = 16

SelText[2] = S

exit

The second SelText is defined with a S. This means that the system will search for a second part using the first point.

exit

In this case the Question text is taken from the standard text file bracketquest0.cmd.

If the angle between the two legs is smaller than 60 degrees, a message will appear, depending on the lang variable. With the CheckMeasure variable you activate the dimension direction panel.

LABEL 3

If the angle between the two big legs is less than 60 degress, the dimension of bracket must by completely defined by the user.

}

exit

The stand variable, defined in the bracket761.inp file, is used to define the default answers. Normally the input fields for a standard are frozen. If value -12345 is assigned, the corresponding input field is not frozen and empty so values can be entered.

In this case the method of definition is different than bracket760.cmd because one line of the macro must not have more than 130 characters.
