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>
