skill code for placing components around circle (polar placement)

KARPCB

 Hi ,

 

Anyone have  skill code for placing components around circle (polar placement) ?

 

Thanks,

Karthik

    Hi All,

     i need skill code for following concept. Experts please help me.

    Step1 : select the required components in layout

    Step2 :Calculate the orgin of the components

    Step3 : enter the radius and angle

    Step3 : find the x and y location on the circle using below formula

    X = R cos(theta)

    Y = R sin(theta)

    P(X1,Y1)

    R=200

    THETA = 30DEGREE

    P(X2,Y2)

    R=200

    THETA = 60DEGREE

    .

    .

    .

    P(X12,Y12)

    R=200

    THETA = 0DEGREE

    Step4: move the component(orgin) and place into the x and y location of the circle

    plesae see the attached image.

    Thanks in advance,

    karthik.

    How much Skill experience do you have?

    Do you want some example snippets or for someone to write this code for you?

    Regards,

    Dave,

    Thanks for reply

    Im 1 month experience in skill language. im not expert like you.

    some examples(step1 and 2) its enough for me to do that skill code.

    Thanks,

    Karthik.

    Try this code:
     
    defun( CircularPlace ()
     let((mypopup, syms, symbols, (continue t), centrePt, radiusStr, radius, angle, angleStr, pt, symAngle)
    ; Create the RMB popup options for Done and Cancel:
    mypopup = axlUIPopupDefine(nil (list (list "Done" 'axlFinishEnterFun), (list "Cancel" "axlCancelEnterFun(), continue = nil")))
    axlUIPopupSet(mypopup)
    ; Select and highlight the symbols to arrange:
    axlSetFindFilter(?enabled '("noall", "SYMBOLS"), ?onButtons '("SYMBOLS"))
    while(axlSelect(?prompt "Select symbols..."); will only continue if one or more objects are selected.
    syms = axlGetSelSet()
    symbols = append(symbols, syms)
    axlClearSelSet()
    axlHighlightObject(syms)
    )
    symbols = unique(symbols); We don't want duplicates
    axlDehighlightObject(symbols)
    and(; Stop if user cancels or anything fails
    continue; Don't continue if the user cancelled
    symbols; Only continue if at least one symbol was selected
    centrePt = axlEnterPoint(?prompts "Select the circle centre", ?gridSnap t); Request the circle centre point
    radiusStr = axlUIPrompt("Enter the radius", "200"); Request the circle radius (a string)
    radius = readstring(radiusStr); Convert the string to a number
    numberp(radius); Ensure that the radius is actually a number
    angle = 360.0 / length(symbols); Calculate the expected delta angle between symbols
    angleStr = axlUIPrompt("Enter the angle", sprintf(nil, "%L", angle)); Allow the user to select an angle
    angle = readstring(angleStr); Convert the string to a number
    numberp(angle); Ensure that the angle is actually a number
    angle = float(angle); The angle needs to be real for axlGeoRotatePt.
    pt = list(car(centrePt) + radius, cadr(centrePt)); This is the starting point.
    symAngle = 0.0; This is the starting angle. *** Change to 90.0 if the component requires it ***
    foreach(sym, symbols
    pt = axlGeoRotatePt(angle, pt, centrePt); Calculate the next point
    symAngle = symAngle + angle; Calculate the next symbol angle
    axlTransformObject(sym, ?move axlMXYSub(pt, sym ->xy), ?angle symAngle - sym ->rotation); Move the symbol.
    )
    )
    ))
