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

    its get work, thank you very much Dave.  i have two question reserved.

    one; how do you kown it has a segments attributions, i check the skill UG, it just as the image i post above there arent a segments attributions in the list, where can find the explain about this?    

    two: what's the different between  ->? and ->??   ?

    1. Refer to the Allegro Skill Reference (algroskill.pdf) Path Attributes.

    2. ->? returns a list of the names. ->?? returns the list of names and values (much more useful usually)

    Hi Dave,

      Do you know how to get the width for path? I want to know the width of lines on "PACKAGE GEOMETRY/ASSEMBLY_TOP". But the line's objType is path. you know only line has width attribute, how could I get the information for path? Please give me your suggestion. Thanks in advance.

    It seems I can get the width by car(myline->segments) ->width, is it correct? Or it is detour way?

    Dave,

      axlPathGetWidth or axlPathSegGetWidth require a r_path parameter, it means _axlPath@. But here, I can get many lines(path) from an existing layer. It will be dbid: -number format. It seems I can't use axlPathGetWidth or axlPathSegGetWidth to get the width's information directly. Any other idea from you? Or I have to use car( myline ->segments) ->width? Thanks for your help.

    Just get the width attribute of the line segments. If your line dbid is lineDBID then car(lineDBID ->segments) ->width will give you a value
