Changing dimension parameters by menu

Jim OMahony

I want to make it easy to dimension component footprints with the appropriate text and arrow head sizes. To do this

I have written some code to read parameter files according to the menu picked :

procedure( exlDimSize( sizeSelect )
    println(list("Dimension taille = " sizeSelect))
        caseq( sizeSelect
                ( "Defaut" axlImportXmlDBRecords( "Y:/LIBRAIRIES/CAO/Cadence/site_env/pcb/parameter/Dim_Defaut.prm"))
                ( "0603" axlImportXmlDBRecords( "Y:/LIBRAIRIES/CAO/Cadence/site_env/pcb/parameter/Dim_0603.prm"))
                (t println("Taille de dimensions pas de modification."))
            );caseq
        axlLayerCreateNonConductor("PACKAGE GEOMETRY/DIMENSIONS")
        axlSetActiveLayer( "PACKAGE GEOMETRY/DIMENSIONS")
);procedure

axlCmdRegister( "dimsize" 'exlDimSize ?cmdType "general")

-----

The problem is that I have to manually reload the skill file first. The file is in my skill directory and loads to a certain extent as I can see the new command "dimsize".

Anyone know why this file has to be loaded a second time in order to work ?

Thanks in advance.

    Hi Jim, so have you added the load function in your allegro.ilinit file to load this skill file automatically at the time of startup? If yes, and you still need to load it again after the Allegro is reinvoked, you can check whether your skill path is correctly set. 

    To check this try below function in the allegro command window:

    getSkillPath()

    This will give you the path which is currently set.

    To add more locations to the SKILL Path you can use setSkillPath as below:

    setSkillPath(buildString(append1(getSkillPath()  "D:/skill")))

    Once done, try to add a printf statement in code to check whether it is loaded at the time of startup or not.

    In fact I put all of my skill files in the $ALLEGRO_PCBENV/site_env/pcb/skill directory and this directory shows up in the SKILL Path.
    I use the traditional allegro.ilinit loop to read all of the .il skill files in this directory. My new file gets read ok and I can
    see and use the command "dimsize" in the command line. Despite that I have to reload the file to get it to work. Not something
    that I have to do for any of the other skill files.
    I have now added a separate load command in the ilinit file just for this file so that it gets loaded twice automatically
    and that seems to do the trick.
    There seems to be something particular about this skill file, I suspect the caseq command as this is the only time that
    I have used it, but that's just a guess.
    Thanks for having a look anyway.
