Setting Target/Direction on Pviewport

[dario_bellinazzi]

Hello,

i'm not getting the expected result with following test code regarding Viewport's Target/Direction:

(defun C:PVPTEST ( / acadObj docObj pSpaceObj ps_centerPt vp_targetPt vp_cameraPt vpObj)
  (setq acadObj     (vlax-get-acad-object))
  (setq docObj      (vla-get-ActiveDocument acadObj))
  (setq pSpaceObj   (vla-get-paperspace docObj))
  (setq ps_centerPt (vlax-3d-point (trans (getvar "VIEWCTR") 0 1)))
  (setq vp_targetPt (vlax-3d-point '(0.0 0.0 0.0)))
  (setq vp_cameraPt (vlax-3d-Point '(0.0 0.0 500.0)))
  (setq vpObj       (vla-AddPViewport pSpaceObj ps_centerPt 5.0 5.0))
  (vla-Display vpObj :vlax-true)
  (vla-put-CustomScale vpObj 0.02)
  (vla-put-Target vpObj vp_targetPt)
  (vla-put-Direction vpObj vp_cameraPt)
)

Resulting viewport should be targeting WCS origin, but I get this instead (Crosshair is on mspace WCS origin):

Same code works fine on other CADs, is there something I'm missing?

Attached you can find test drawing/function.

Thank you for your help.

This is the VBA forum. You want the lisp forum here.

Ok. I thought this was the right forum, since the code is LISP flavor of ActiveX/COM API.

Going there then.
