Using SKILL to draw over the PCB design

SergeiR

Hello, I'm new to Allegro and SKILL, and am currently looking into using SKILL scripts to draw graphics over the board design.  I've looked at the example script included with Allegro (axlform.il), where the axlGRPDrw* functions are used to draw on a separate form, but have not been able to modify that code to draw in the main view.  So, I was wondering if what I am trying to do is possible, and if so where could I find some documentation and/or examples on how to do this.

Thanks,

-Sergei

  • What you need to then is to keep a list of the newly created items. Each axlDBCreate function returns a list of dbID. Add these ID's to a list and once you stop the function you can delete them with axlDeleteObject.

    So something like:

    ; make a new list

    l_items = list(nil)

    ;add items with nconc. 'appends' a list to a list, but changes the l_items destructively)

    nconc( l_items  car(axlDBCreateLine( (list 1:1 5:5), 1, "etch/top")) )

    nconc( l_items  car(axlDBCreateLine( (list 10:10 20:20), 1, "etch/top")) )

    ...

    ;remove any 'nil' items

    remdq(nil l_items)

    ;now the l_items contains the newly created dbID's. You can delete them

    axlDeleteObject(l_items)
