VLAX error confusing.

R2005:

I have an error trying to AddEllipse.

I ran it from the vlide with no help on what exactly is wrong.

; error: Automation Error. Description was not provided.

(setq MaAxLen (vlax-make-variant ds1 vlax-vbDouble))
(vlax-invoke-method (list *modelspace* 'AddEllipse (vlax-3d-point pt1) MaAxLen rt)

So i run it form the command prompt:

Command: ; error: Automation Error. Description was not provided.

So after reading the help files and searching this forum, it seems to me I need to add a catch-all error to help discipher this generic error, so I add to program.

(setq ErrMsg (vl-catch-all-apply
'vlax-invoke-method (list *modelspace* 'AddEllipse (vlax-3d-point pt1) MaAxLen rt)
))

(if (vl-catch-all-error-p ErrMsg)
(prompt (strcat "Exception: " (vl-catch-all-error-message ErrMsg)))
)

Now I run the program again I get:

Coomand: Exception: Automation Error. Description was not provided.

Can I get some help for this?

TIA

Bill

 

The MajorAxis argument needs to be a point, not a simple double. See the
example in the docs and not just the incorrect description.
