SKILL routine for shape logical operations (boolean)?

Sonoma

Hi all,

I am looking for a SKILL routine that would allow me to do logical operations on shapes inside the Allegro PCB editor (currently running XL version 16.2). Specifically I'd like to be able to apply a Logical AND, Logical OR, and Logical ANDNOT to two previously existing shapes to create a new shape. I know there is some AXL-SKILL code to do such a thing but have not seen any routines.

 Any ideas on if such a thing exists, and where I could find it?

Regards.

  • Indeed these operations are possible.

    Take a look at the axlPolyOperation command.

    The example given is:

    poly1_list = axlPolyFromDB(cline_dbid)
    poly2_list = axlPolyFromDB(shape_dbid)
    res_list = axlPolyOperation(poly1_list poly2_list 'OR)

     Regards, Dave

     

  • Correct, this should be something that can be done. I looked in the PCB Editor Users Guide: SKILL Reference (version 16.2)....if you go to Section 20, it discusses the commands to do this.

    I was used to doing this in Virtuoso, and find myself frustrated that it's not available in Allegro. I believe that this functionality (plus more) is available in the RF PCB version of Allegro. At this point, I'd be happy to just have the basic logical operations.

    However, I'm not a SKILL programmer (at least not yet)....Does anyone know of any existing routines that could be called from Allegro?

    Appreciate it.
