Topic: vlax-3D-point to list

[CAB]

If you use this (vlax-3D-point list) to create a vlax point
How do you reverse the process?

[MP]

(vlax-safearray->list (vlax-variant-value (vlax-3D-point '(0 0 0))))

[CAB]

Well you can tell I don't use that one very often.
You would think the help file would have a clue in the vlax-3D-point command
as to how to reverse the process. Oh well.

Thanks Michael

Hi CAB

You can also use the VitalLisp part of ActiveX:

Code: [Select]

(vla-get-StartPoint Obj)
;can be replaced by:
(vlax-get Obj 'StartPoint)
;and returns directly a list...
or:
(vla-put-StartPoint Obj (vlax-3D-point '(0 0 0)))
;can be replaced by:
(vlax-put Obj 'StartPoint '(0 0 0))
Cheers

Thanks for the help Jürg, very informative.
That reminds me that ther was a thread about the difference in the two methods.
Now if I can only find it.

OK, here it is.
Your example sparked my dim memory of this post.

Always wondered about the exact origin of those functions. Good info. Thanks mr. Menzi.

I wish Autodesk never bought Vital LISP from BASIS Software. Vital LISP today would kick Visual LISP's butt around the block (Autodesk have let it languish), we'd have actual secure output (arx) and you wouldn't have to run it inside AutoCAD.

I agree MP. I still have my original manuals around here somewhere.

I recall the disappointment I felt with each subsequent release by AutoDesk when nothing was done to expand on the work BASIS did on the product.

I still remember getting version 2 and rubbing me hands gleefully "Excellent Smithers, let's bash some serious apps out, w00t!". Last version I had round here was 3 Professional (IIRC). Now where are those manuals ...

... 'Course, I remember AutoDIRECT too. Man, time flies ...

I suppose they are printed manuals? If so, you know how OCR scanning works, right?
