Examples

The following example uses the AddCircle method to draw a circle in the current AutoCAD drawing.

The first argument to AddCircle specifies the location of the center of the circle. The method requires the center to be specified as a variant containing a three-element array of doubles. You can use vlax-3d-point to convert an AutoLISP point list to the required variant data type:

(setq circCenter (vlax-3d-point '(3.0 3.0 0.0)))
#<variant 8197 ...>

Now use vlax-invoke-method to draw a circle with the AddCircle method:

(setq mycircle (vlax-invoke-method mspace 'AddCircle circCenter 3.0))
#<VLA-OBJECT IAcadCircle 00bfd6e4>
