FindXYAtOffsetAndElevation API Via Lisp Fail

[davilavanegas]

Hello,

I am trying to use FindXYAtOffsetAndElevation for SectionViewObject via Lisp, but it fail.

I get error: ActiveX Server returned the error: unknown name: FindXYAtOffsetAndElevation

Instead when a use FindStationAndElevationAtXY I get correct result.

(defun offelev ( obj off elev / x y point)
  (vlax-invoke-method obj'FindXYAtOffsetAndElevation 'off 'elev)
  (setq point (list off elev))

;;example
(setq ent (car (entsel "\nSelect SectionView"))
      obj(vlax-ename->vla-object ent)
      off (vlax-get-property obj 'OffsetLeft)
      elv (vlax-get-property obj 'ElevationMin)
      )
(offelev ojb off elv)

Functions with station in the name are for Profile Views. Maybe show the calling function.

.NET API

SectionView.FindOffsetAndElevationAtXY

SectionView.FindXYAtOffsetAndElevation

ProfileView.FindStationAndElevationAtXY

ProfileView.FindXYAtStationAndElevation

The method you are specifying does not exist. Try this:

(defun offelev ( obj sta off elev / x y point)
  (vlax-invoke-method obj 'FindXYAtStationOffsetAndElevation sta off elev 'x 'y 'inside)
  (setq point (list off elev))
  )

;;example
(setq ent (car (entsel "\nSelect SectionView"))
      obj(vlax-ename->vla-object ent)
      off (vlax-get-property obj 'OffsetLeft)
      elev (vlax-get-property obj 'ElevationMin)
      sta (vlax-get (vlax-get obj 'parent) 'station)
      )
(offelev obj sta off elev)

I dont know why my reply posted twice. Nor do I know why Autodesk thought the Station was needed since the SectionView selected is the one being worked with.
