Cutout & lugs section

However, in the case of cutouts and lugs, the profile height and thickness usually determine which variables should be sent to the construction database. A label 5 has been added to the type macro for this special case.

Label 5 only applies to cutouts and lugs, since the cutout (and therefore lugs also) is created around a profile. The dimensions of this profile are known when label 5 is executed, which makes it possible to assign the R variables in accordance with the profile type.

Cutout variables

With cutouts, the linking of the R variables to the answers given is divided into two parts. The first part consists of the answers given under labels 1 to 3. These variables are stored in the VarStr variable. The second part is the storing of the R variables. These are usually calculated or determined by the dimensions and type of the profile. These R variables are stored in the VarCutOut string.

In label 5, several variables calculated by CADMATIC Hull are already known. These are:

 

These variables are useful for calculating the R variables, of which the following is an example.

if prof_type[1\2]='hp' then

{

#  It is a bulb flat (HP)

if prof_height=80     :varcutout='r1 35 r2 56 r3 2 r4 10 r5 70 '

if prof_height=100   :varcutout='r1 35 r2 59 r3 2 r4 10 r5 70 '

if prof_height=120   :varcutout='r1 35 r2 60 r3 2 r4 10 r5 75 '

if prof_height=140   :varcutout='r1 35 r2 63 r3 2 r4 10 r5 75 '

if prof_height=400   :varcutout='r1 35 r2 110 r3 2 r4 10 r5 85 '

if prof_height=430   :varcutout='r1 35 r2 119 r3 2 r4 10 r5 85 '

}

if prof_type[1\2]='hg' |prof_type[1\2]='ho' then

{

varcutout='r1 35 r3 2 r2 '<prof_flange+35>' r4 10 r5 50 '

}

if prof_type[1\2]='st' then

{

varcutout='r1 35 r3 2 r2 75 r4 10 r5 50 '

}

Lug variables

The same variables as for cutouts as described above can be used at label 5 of a lug type macro, but with the following differences:

- use VarLug instead of VarCutOut

- use r9 - rg instead of r1 - r8

Consult the Eagle syntax manual for an explanation of the 'if' command.

Always ensure that all opening parentheses { you have used are balanced by closing parentheses }. Failure to do so might lead to glitches and errors.
