Да ме прощаваш, но говориш глупости. В Help-а на AutoCAD-а си има цели раздели - "ActiveX and VBA Developer's Guide" и "ActiveX and VBA Developer's Reference" и вътре има описано ВСИЧКО. Сега не искам да ти копирам целия Help, на ето ти пример за "Offset":

Offset Method

Creates a new object at a specified offset distance from an existing object.

See Also | Example

Signature

RetVal = object.Offset(Distance)

Object

Arc, Circle, Ellipse, Line, LightweightPolyline, Polyline, Spline, XLine
The object or objects this method applies to.

Distance

Double; input-only
The distance to offset the object. The offset can be a positive or negative number, but it cannot equal zero. If the offset is negative, this is interpreted as being an offset to make a "smaller" curve (that is, for an arc it would offset to a radius that is "Distance less" than the starting curve's radius). If "smaller" has no meaning, then it would offset in the direction of smaller X, Y, and Z WCS coordinates.

RetVal

Variant (array of objects)
An array of the newly created objects resulting from the offset.

Remarks

For many curves, the result of this operation will be a single new curve (which may not be of the same type as the original curve). For example, offsetting an ellipse will result in a spline because the result does fit the equation of an ellipse. In some cases it may be necessary for the offset result to be several curves.
