T circle command In AutoCAD
The diameters of the circles, and the width and height of the slots and rectangles can be constant or variable. Variable sizes adjust to the size of each selected text or mtext object based on the distance offset factor. The Constant option encloses selected text and mtext objects with objects that are all the same size, the size of the largest enclosing object.
