Topic: Trap with vla-ArrayPolar

[Kerry]

With vla-ArrayPolar the returnValue is

Variant Array (array of objects)
The array of new objects

note the word 'NEW'

So, if we want to do something like solid subtraction of a collection of arrayed objects
the original object needs to be added to the collection returned from vla-ArrayPolar

Short example :

Code: [Select]

<.. snip ..>
  (setq ObjArray (vla-ArrayPolar
                   extObj
                   flg_hqty
                   (* pi 2)
                   (vlax-3d-Point p1w)
                 )
  )
  (foreach penetration (cons extObj (safearray-value (variant-value ObjArray)))
    (vla-boolean bodyObj acsubtraction penetration)
  )
<.. snip ..>
