Reading Object Properties

Functions that read object properties are named with a vla-get prefix and require the following syntax:

(vla-get-propertyobject)

For example, vla-get-center returns the center point of a circle.

To obtain an object's property and apply the property to a new object

Enter the following at the VLISP Console prompt:
```
(setq myCircle (vla-addcircle
mspace (vlax-3d-point 
```
```
  (getpoint "\nPick
the center point for a circle: ")) 2.0))
```
This function call prompts you to pick a center point for a circle, then invokes the Addcircle method to draw the circle. The vlax-3d-point function converts the point you pick into the data type required by vla-addcir-cle.
Use vla-get-center to draw a second circle concentric to the first:
```
(vla-addCircle mSpace
(vla-get-center myCircle) 1.0)
```
The AutoCAD drawing window now contains the following objects:
