skill code for design Sheet Size need help

Junior0304

Hi guys,

I am writing a skill code that will check Design parameters that include User Units, Accuracy and Size.

I was able to get the units and the accuracy using axlGetParam("paramDesign"), but no luck on the sheet size.

Can somebody please help help.

my  code is something like this

d = axlGetParam("paramDesign");
if(nequal(d->units "millimeters") then
       axlUIConfirm("Design unit defined is non-standard, change to millimeter and try again.")

else

)

if(equal(d->accuracy 4) then
...
else
...
);if

  • Use axlDBGetDesign() ->bBox to get the design extents. This isn't a sheet size as no such concept exists in Allegro - although you can use axlExtentDB to get the extents of certain layout objects.

    Note that axlDBGetDesignUnits is an alternative to getting units and accuracy.

  • Thanks eDave,

    Actually the code is checking if  the created .dra  follows our standard settings

    and i need to check the size.. A1, A4,,other  as  the attached image.

  • Ok. axlDBGetDesign() ->bBox will give you some numbers but they won't be useful. If you have a sheet that has a border you can certainly measure that by getting the maximum and minimum extents of anything on that layer.

    I'm wary of populating dra's with additional graphics as these can vastly increase your design database sizes. I do add a sheet but temporarily delete it before compiling the symbol.

  • Thanks again eDave, 

    I do not have and not adding any sheet,

     but i need to check the .dra settings after the creator saved the symbol;

    and that check includes what is the design units, accuracy and sheet size  settings.

    Because in our footprint  creation SOP, the .dra should  be in millimeter, with 4 accuracy and size of A1.

    any other setting will trigger an error report, and that is the task of the skill program. 

    Actually, my lead is planning to add the check of long name size as well. ;)

    Your help is much appreciated.

  • Just curious. Why is the drawing size controlled in your SOP? The size is the size. Surely the smaller the design extents the better.
