about lines startend points

tennywhy

i want get all lines start and end points on outline layer, there is the code

defun( apl ()
    let( (RLP symbPg symbPth allSymbols allSymbolss)
    ;print all lines startend point
    axlSetFindFilter(?enabled list("noall" "lines")
        ?onButtons list("noall" "lines"))
    allSymbols = axlGetSelSet(axlAddSelectAll())
    axlClearSelSet()
    foreach( everyLine allSymbols
            axlMsgPut("startis %L" everyLine->startEnd) ; it doesnt work
            ;axlMsgPut("startis %L" everyLine->?) ;checked it has startEnd properties
            ;axlMsgPut("startis %L" everyLine->??) ;checked it has startEnd properties  
            )
 ))

what's the right way ?  and in the skill UG there is a starEnd attribute as in image below. how could i do it ?

    startEnd is and attribute of a line segment - not the symbol itself.

    use something like

    foreach(symbol, allSymbols

      foreach(pathObj setof(obj, symbol ->children, obj ->objType == "path")

        foreach(segment, pathObj, ends = segment ->startEnd

    axlCmdRegister( "autoPlace" 'autoPlace)
    defun( autoPlace ()
        let( (RLP symbPg symbPth allSymbols allSymbolss)
        axlSetFindFilter(?enabled list("noall" "Lines")
            ?onButtons list("noall" "Lines"))
        allSymbols = axlGetSelSet(axlAddSelectAll())
        axlClearSelSet()
        foreach(symbol, allSymbols
             ;printf("symbol is %L" symbol) ;can be get right dbid at here
             foreach(pathObj setof(obj, symbol ->children, obj ->objType == "path")
                 ;printf("pathObj is %L" pathObj) ;nothing at here
                 foreach(segment, pathObj, ends = segment ->startEnd
                 ;printf("ends is %s" ends) ;nothing at here
                              )))
    ))

    ;========================================================

    1) this is my code , my purpose is get all lines at visible layer , and list all line segments start and end point.

    2) i have tested the symbol attributes use symbol->?? it seem as not children attributes

    3) it seem as symbol->? also displayed some attributes, what different  ->? and ->?? ,  if ->? dispalyed attributes can not be refernce directely ?

    You set your find filter to "lines" and then expect to get symbols returned!
