Copying symbols for creating padstacks.

mikebystedt

I'm trying to copy padstack information so that I can create a slightly modified version. 

As an example:
When I grab the data structure for the original pad type, it's a string ("ANTIPAD", "THERMAL", etc...) instead of a symbol.
So I can't easily pass it along.

I had to put it into a case statement to assign the type that I want.  
Then I tried to use stringToSymbol and use that so I didn't need a case statement at all.

Any suggestions on why this doesn't seem to work?
ps = axlLoadPadstack(padStackName)
padId = car(ps->pads)

padId->type returns "THERMAL" (a string and not a symbol).

newPad->type = stringToSymbol(padId->type)
*This is no good.*

 /***  This seems to work though.  **/

case(padId->type

("ANTIPAD" type = 'ANTIPAD)

("THERMAL" type = 'THERMAL)

("REGULAR" type = 'REGULAR)

(t type = nil)

);End type case.

newPad->type = type
 

I'm obviously doing something incorrectly here.  Any help is greatly appreciated!

  • OK Mike, I figured it out:

    The problem is with the ANTIPAD type. The pad type attribute is actually "ANTI" but you must pass 'ANTIPAD to ?type in make_axlPadStackPad. Passing nil won't report an error (but would not work properly) but passing 'ANTI will - hence the difference between the two methods.

    You can use padType = stringToSymbol(pad ->type) but you will need to add an extra statement: when(padType == 'ANTI, padType = 'ANTIPAD).

  • Big thanks guys, I'll give it another shot.
    I could have possibly stared at that for days and still not eyeballed the difference.
    You guys are good!

    Best Regards,

    -Mike
