Can SKILL recognize which edge is selected in a rectangle(or path/wire etc...)?

LoTJF

Hi experts,



  Even If I partially select some edges, I can't get information of which edge(e.g. upper/lower/right/left) is selected.

The only thing I could get is the whole object. Do you have any function or workaround for this?

  • You can use geGetSelSetFigPoint(figId) to determine which vertices in the partially selected object are selected.

    Regards,

    Andrew.

  • Andrew,

        Thank you for the prompt response, but what is the order of those four output Boolean value? 
    It's not described in the manual, is it (TL,BL,BR,TR) ? 

  • Andrew, Thank you for the prompt help, but no description of the order of those four output Boolean values in the manual. Is it (TL, BL, BR, TR) ?

  • For objects with a points attribute, e.g. polygons, it's the points as is. For rectangles, I looked through my code and I've used this to generate a list of points in the right order for comparing with the results of this function:

    /******************************************
    *                                         *
    *          (abBBoxToPoints bbox)          *
    *                                         *
    * Convert a bounding box to a point list. *
    *                                         *
    ******************************************/

    (procedure (abBBoxToPoints bbox)
      (list
       (lowerLeft bbox)
       (list (xCoord (lowerLeft bbox)) (yCoord (upperRight bbox)))
       (upperRight bbox)
       (list (xCoord (upperRight bbox)) (yCoord (lowerLeft bbox)))))

    So that's LL UL UR LR.


    So then I do things like (in C-style):

    foreach((point sel) abBBoxToPoints(obj~>bBox) geGetSelSetFigPoint(obj)
      when(sel
        printf("Point %L selected\n" point)
      )
    )

    (note the above 5 lines weren't tested)

    Andrew.

  • Andrew, Thank you for your prompt support. This is what I want. Wish you a good day.
  • By the way, you might want to think about changing your profile name - your last three posts (at least) went into moderation, and given that there was nothing unusual about the text of your posts, I suspect it's the profile name which causes the problem...
