I Need Help Creating a Shape With a Void on Route Keepout in Allegro

MarkGorecki

Hello,

I followed the instructions in the Allegro X PCB Editor Skill Programming Language course, but it seems to be missing something.

Shown below is my code to create a rectangular shape, with rounded corners, then add a void, also with rounded corners, to that shape.

procedure(CreateHSKO_Callback(formStatus)
let( (lidX lidY cavityX cavityY lidType lidRadius lidCham cavRadius
lidX1 lidX2 lidX3 lidX4 lidY1 lidY2 lidY3 lidY4 chamX chamY cavX1 cavX2 cavX3 cavX4
cavY1 cavY2 cavY3 cavY4 hsPath voidPath)
lidX = 0
lidY = 0
cavityX = 0
cavityY = 0
lidType = nil
lidRadius = 0
lidCham = 0
cavRadius = 0
lidX1 = 0
lidX2 = 0
lidX3 = 0
lidX4 = 0
lidY1 = 0
lidY2 = 0
lidY3 = 0
lidY4 = 0
chamX = 0
chamY = 0
cavX1 = 0
cavX2 = 0
cavX3 = 0
cavX4 = 0
cavY1 = 0
cavY2 = 0
cavY3 = 0
cavY4 = 0
hsPath = 0
voidPath = 0

case(formStatus~>curField
("dwgNum" dwgNumber = formStatus~>curValue)
("done"
hsPort = infile("C:/_Temp/SKILL/Test_HeatSpreader_Data.csv")
numFound = "F"
when(hsPort
while(gets(txtLine hsPort)
infoList = parseString(txtLine ",")
listDwgNum = nth(0 infoList)
printf( "Drawing Number: %s\n" listDwgNum )
if(listDwgNum == dwgNumber then
numFound = "T"
;Flat Top Lid - 1500chamfer/500rad corner : 1000 rad cavity
;Single Piece Lid - 500rad corners : 1000 rad cavity
;2 Piece Stiffener/Stiffener Only - 1500chamfer : 1000 rad cavity
lidX = atof(nth(1 infoList))
lidY = atof(nth(2 infoList))
cavityX = atof(nth(3 infoList))
cavityY = atof(nth(4 infoList))
lidType = nth(5 infoList)
lidRadius = 500.0
lidCham = 1500.0
cavRadius = 1000.0

lidX1 = (lidX / 2.0) * -1
lidX2 = (((lidX / 2.0) - lidRadius) * -1)
lidX3 = (lidX / 2.0) - lidRadius
lidX4 = lidX / 2.0
lidY1 = (lidY / 2.0) * -1
lidY2 = (((lidY / 2.0) - lidRadius) * -1)
lidY3 = (lidY / 2.0) - lidRadius
lidY4 = lidY / 2.0
chamX = lidX1 + lidCham
chamY = lidY4 - lidCham
cavX1 = (cavityX / 2.0) * -1
cavX2 = (((cavityX / 2.0) - cavRadius) * -1)
cavX3 = (cavityX / 2.0) - cavRadius
cavX4 = cavityX / 2.0
cavY1 = (cavityY / 2.0) * -1
cavY2 = (((cavityY / 2.0) - cavRadius) * -1)
cavY3 = (cavityY / 2.0) - cavRadius
cavY4 = cavityY / 2.0
; Create the lid outline
if(lidType == "FTL" then
hsPath = axlPathStart((list lidX2:lidY1) 0)
hsPath = axlPathLine(hsPath 0.0 lidX3:lidY1)
hsPath = axlPathArcCenter(hsPath 0.0 lidX4:lidY2 nil lidX3:lidY2)
hsPath = axlPathLine(hsPath 0.0 lidX4:lidY3)
hsPath = axlPathArcCenter(hsPath 0.0 lidX3:lidY4 nil lidX3:lidY3)
hsPath = axlPathLine(hsPath 0.0 chamX:lidY4)
hsPath = axlPathLine(hsPath 0.0 lidX1:chamY)
hsPath = axlPathLine(hsPath 0.0 lidX1:lidY2)
hsPath = axlPathArcCenter(hsPath 0.0 lidX2:lidY1 nil lidX2:lidY2)
)
if(lidType == "SPL" then
hsPath = axlPathStart((list lidX2:lidY1) 0)
hsPath = axlPathLine(hsPath 0.0 lidX3:lidY1)
hsPath = axlPathArcCenter(hsPath 0.0 lidX4:lidY2 nil lidX3:lidY2)
hsPath = axlPathLine(hsPath 0.0 lidX4:lidY3)
hsPath = axlPathArcCenter(hsPath 0.0 lidX3:lidY4 nil lidX3:lidY3)
hsPath = axlPathLine(hsPath 0.0 lidX2:lidY4)
hsPath = axlPathArcCenter(hsPath 0.0 lidX1:lidY3 nil lidX2:lidY3)
hsPath = axlPathLine(hsPath 0.0 lidX1:lidY2)
hsPath = axlPathArcCenter(hsPath 0.0 lidX2:lidY1 nil lidX2:lidY2)
)
if(lidType == "2PS" || lidType == "SO" then
hsPath = axlPathStart((list lidX1:lidY1) 0)
hsPath = axlPathLine(hsPath 0.0 lidX4:lidY1)
hsPath = axlPathLine(hsPath 0.0 lidX4:lidY4)
hsPath = axlPathLine(hsPath 0.0 chamX:lidY4)
hsPath = axlPathLine(hsPath 0.0 lidX1:chamY)
hsPath = axlPathLine(hsPath 0.0 lidX1:lidY1)
)
hsShape = axlDBCreateOpenShape(hsPath t "ROUTE KEEPOUT/L01" nil)
voidPath = axlPathStart((list cavX2:cavY1) 0)
voidPath = axlPathLine(voidPath 0.0 cavX3:cavY1)
voidPath = axlPathArcCenter(voidPath 0.0 cavX4:cavY2 nil cavX3:cavY2)
voidPath = axlPathLine(voidPath 0.0 cavX4:cavY3)
voidPath = axlPathArcCenter(voidPath 0.0 cavX3:cavY4 nil cavX3:cavY3)
voidPath = axlPathLine(voidPath 0.0 cavX2:cavY4)
voidPath = axlPathArcCenter(voidPath 0.0 cavX2:cavY1 nil cavX2:cavY2)
axlDBCreateVoid(hsShape voidPath)
axlDBCreateCloseShape(hsShape)
) ;if dwgNumber
) ;while
if(numFound == "F" then axlUIConfirm( "Drawing number not found!" ))
)
close(hsPort)
axlFormClose(myform)
)
("cancel"
axlFormClose(myform)
)
) ;case
) ;let
)

I get this error:

W- *WARNING* (axlDBCreatePath): Not an r_path defstruct - 0

W- *WARNING* (axlDBCreateOpenShape): Object should be either an r_path or an o_polygon - 0

I created the paths like they showed, as the course said "The first argument is a path handle created with the axlPath () functions previously discussed."

If someone would help me out, I would really appreciate it.

Best regards,

Mark

    Hi Mark,

    Most of your code won't execute correctly because you have used "~" in place of "-" in formStatus~>curField and formStatus~>curValue

    BTW, you don't need to (read "shouldn't") zero all your variables. They are declared correctly as nil in your let statement.

    Regards,

    Dave

    Hi Dave,

    Thank you for checking out my code and for the advice.  I also found an error in my void path.  It's working now.

    I would recommend using sklint() to check your code, below is the results I got:

    Hi David, thank you for that info.  I'll look into sklint.
