Bracket type 791

Bracket type 791 is a default bracket whose dimensions are calculated according to the profile height. In special cases the system adds a flange according to the profile height and the angle of the bracket. The bracket will be overlapped when the profile is bigger than 160 mm.

R variable

Default

Question

R1

Calculate from height of profile

Enter width of bracket

R2

In this case the SelText uses the standard text from the brackethint0.cmd file.

 

 

When Planview is defined, the bracket can be placed as a cross section bracket. The value (1 or 2) defines whether the related part in plan view is the 1st or 2nd relation of the bracket.

This bracket is only possible in this situation if the profile height is 4 times bigger than the thickness of the profile.

The bracket gets panel code YA.

Depending of the gap, the profile height or/and angle and the answers given in the panel (offset and extra length), a bracket type is chosen with an extension of a,b,c,d,e or f.

 

 

A flange will be added depending of the profile height and the length of the flange.

The default description for bracket defined in the System Management application will be used.

Controlling extra length and offset:

The tab file is manually changed after the first use of the bracket. This change takes care of two pull-down menus to control the plane (offset) of the bracket and the extra length. Specially for this reason, two files are made to illustrate the possibilities in the panel: shift791.dat and over791.dat. In these files contain the information shown in the drop-down menu.

shift791.dat

over791.dat

Automatic

No offset

Automatic

With extra Length

In this case the offset and extra length are controlled by the bracket_user macro. The BracketNumber variable must be used to control more than one bracket type.

-ncgnorms/bracket/bracket_user.cmd


label init

if BracketNumber=791 then

{

 unfreeze p=FunctieID, b=qn[6]

 unfreeze p=FunctieID, b=qn[8]

 if ans[3]=1 : click p=FunctieID, b=qn[6],t=2

 if ans[4]=1 : click p=FunctieID, b=qn[8],t=2

}

exit

In this case the init label is used to unfreeze the offset and extra length buttons even by the use of a standard bracket and to select the proper previous selection.

label execute

{

 unfreeze p=FunctieID, b=qn[6]

 unfreeze p=FunctieID, b=qn[8]

 if bn=qn[6] then

   if st='Automatic' : ans[3]=0

   if st='No offset' : ans[3]=1

 }

 

 if bn=qn[8] then

 {

   if st='Automatic' & ans[4]=1 then

   {

     if HP[1]=<140 : ans[4]=0

     if posnr<>'' & stand<>'free' then

     {

       if HP[1]=<140 : PosNr=<^PosNr60>

       insert p=FunctieID, b=98, t=Posnr

     }

   }

   if st='With extra length' & ans[4]<>1 then

   {

     if HP[1]=<140 : ans[4]=1

     if posnr<>'' & stand<>'free' then

     {

       if HP[1]=<140 : PosNr=<^PosNr+60>

       insert p=FunctieID, b=98, t=Posnr

     }

   }

   {

     Tel 'Choise not allowed'

     click p=FunctieID, b=qn[8],t=2

   }

   if st='With extra length' & ans[4]<>1 then

   {

     Tel 'Choise not allowed'

     click p=FunctieID, b=qn[8],t=1

   }

 }

}

exit

The execute label is used to control the Ans[x] variables 3 and 4. Also the choice can be disabled or allowed in this situation.

The if statement must be used to control it for only this BracketNumber. If this general macro is used for more bracket types, use the same method by adding an additional if statement:

if BracketNumber=XXX then

{
