How to get the lower level shapes in skill?

jiangzhou

I want to get the lower level shapes in an area.Also,I saw a post in forum.

Code  writing like below:

******************************************************

procedure(abGetOverlapShape(overlap)
  if(listp(overlap) then
      abGetOverlapShape(cadr(overlap))
  else
      overlap
  )
)

cv=geGetEditCellView()

figList2= dbGetOverlaps(cv list(car(pts) car(pts)) list("M2" "drawing") 32 t)

flattenendFigList2=foreach(mapcar overlap figList2
  srcShape=abGetOverlapShape(overlap)
  dbCopyFig(srcShape cv dbGetHierPathTransform(overlap))
)

******************************************************

But 'dbGetHierPathTransform' is used for IC6.1.How can I replace it in IC5.1?Thanks!!

  • You can use this:

    /*****************************************************************
*                                                                *
*                (abGetOverlapTransform overlap)                 *
*                                                                *
* Get the transform needed to transform the shape in the overlap *
*           into the current cell's coordinate system            *
*                                                                *
*****************************************************************/

(procedure (abGetOverlapTransform overlap)
  (let (transform)
       (if (listp overlap)
           (setq transform (dbConcatTransform 
                            (abGetOverlapTransform (cadr overlap))
                            (or
                              (dbGetq (car overlap) transform)
                              (list (dbGetq (car overlap) origin)
                                    (dbGetq (car overlap) orient)
                                    1.0)
                              )
                            ))
           (setq transform (list 0:0 "R0" 1.0)))
       transform
       )) 

     

     

  • Thank you,Andrew .But if get shape from mosaic,error occurs.

    How to  deal with this problem?Thanks!!

  • Rewrite the code to handle mosaics!

    I'm afraid I don't have time to do that now (in the code where I was using this I explicitly checked if the object was a mosaic and made no attempt to handle them - it's not that difficult though). I have a heavy schedule this week and so can only give quick answers on the forum.

    Sorry!

    Andrew.

  • Thank you!

    If you have time,can you tell me the method to get the origin of every instance in mosaic?

  •  dbGetTrueOverlaps has an optional argument to return the row and column of the mosaic instance of the found shape. Then multiply the rows by the Y pitch and the columns by the X pitch and use that when transforming the shapes.

    Create a simple cell with two rectangles. Then place it in several mosaics with different rotations. Test your algorithm using this simple cell then you can build it into Andrew's code.

  •  What is mosaic ?

    What the special features in it ?

     

  • An array. If when creating an instance you specify the number of rows and columns then it will be a mosaic, not a single instance. That complicates things a little!
