Grid Settings

Jerry Wilson

Hi Everyone

I'm going  work on a skill code to read the grid settings of a design.

 I have attached the snap shot. Please advice on how to get the grids value.

Regards

Jerry

     Hi Jerry,

     I'd like to know how to do this too. Did you ever find a way?

    You might want to post this question to the PCB SKILL forum instead of the PCB Design forum, as it's a SKILL question.

    You can try using the undocumented 16.3 command axlDBGridGet. It will give you grid information for etch subclasses.

    e.g. axlDBGridGet("TOP") => (nil name "TOP" objType "grids" readOnly nil xOrigin 0.0 yOrigin 0.0 xMajor 1.0 yMajor 1.0 xGrids (1.0) yGrids (1.0))

    If you still need it, I have some code that will get all the grid form information but it's a real kludge.

    Hi Dave

    Yes please. Can you send the code over.What i have done is instead of checking, i have permenantly set the grids in my code to be 0.001

    axlShell("define grid")

    axlShell("setwindow form.grid")

    axlShell("FORM grid non_etch non_etch_x_grids 0.001")

    axlShell("FORM grid non_etch non_etch_y_grids 0.001")

    axlShell("FORM grid all_etch all_etch_x_grids 0.001")

    axlShell("FORM grid all_etch all_etch_y_grids 0.001")

    axlShell("FORM grid done")

     

     

    Thanks\

    Jerry.

    Hi Evan

    I was unable to check the grids. What i have done is set the grid permanently to 0.001.

    axlShell("define grid")

    axlShell("setwindow form.grid")

    axlShell("FORM grid non_etch non_etch_x_grids 0.001")

    axlShell("FORM grid non_etch non_etch_y_grids 0.001")

    axlShell("FORM grid all_etch all_etch_x_grids 0.001")

    axlShell("FORM grid all_etch all_etch_y_grids 0.001")

    axlShell("FORM grid done")

    Regards

    Hi Jerry,

    See attached. I hope you can figure out how to use it without help.

    This is a usage example: 

    layers = AFn_getGridSettings()\

    layers["TOP"] ->spacingx

    Regards,

    Dave
