Closing a spline?

R2005 Vlisp:

I'm having a go of it with a spline that was created in Vlisp.

Command: (vlax-put-property sp_line 'closed :vlax-true)
; error: ActiveX Server returned an error: Type mismatch

I can close the spline with the splinedit command but when I check the spline to see if the property can be modified, I get:
Command: (vlax-property-available-p sp_line 'closed T)
nil

Anyone know how to do this?

Me thinks BillZ is going through all the ACAD entities and lisp functions to
see which ones he can break........ ;-)

According to the help for creating a spline:
To close a spline, use the Closed property once the spline has been created.

According to the help for the "closed" property:
Boolean; read-write

And yet a vlax-dump on a spline object give this:
; IAcadSpline: AutoCAD Spline Interface
; Property values:
; Application (RO) = #<VLA-OBJECT IAcadApplication 00a8a730>
; Area (RO) = 55155.0
; Closed (RO) = 0 <<<<<<<<<<<<< RO means READ ONLY!!!!!!!!!!
; Color = 256

What's up with that?

No answers, just more questions,

spline to see if the property can be modified, I get:

BUSTED! ( :^ 0

I noticed the big (RO) too just a while ago.

They surely don't want us to go back to (command "splinedit"

There must be another way.
