So far, the data in the polypoints variable is in a list format suitable for many
AutoLISP calls. However, the data is to be supplied as an input parameter to an ActiveX
call that expects a variant array of doubles. You can use another utility function
to make the required conversion from list to variant:
(defun gp:list-variantArray (ptsList / arraySpace sArray) ; allocate space for an array of 2d points stored as doubles (setq arraySpace (vlax-make-safearray vlax-vbdouble ; element type (cons 0 (- (length ptsList) 1) ) ; array dimension ) ) (setq sArray (vlax-safearray-fill arraySpace ptsList)) ; return array variant (vlax-make-variant sArray) )
The following actions take place in gp:list-variantArray:
The following is an example of a function call that invokes gp:list-variantArray to convert a list to a variant array of doubles:
; data conversion from list to variant (setq VLADataPts (gp:list-variantArray polypoints))
