Controlling AutoCAD from Visual LISP (AutoCAD expert's Visual LISP Book 2)

Volume 2 includes Part 3 (Controlling AutoCAD from Visual LISP) of the paperback edition of the Book "AutoCAD expert's Visual LISP".
In this part of the book we will study the techniques available to create new drawing entities and objects, for selecting them according to precise selection filters and for transforming them. As has been our approach from the beginning, but now applying it in the solution of practical tasks, we will continue developing a library of functions, a real programmer’s toolbox which we will be using in the applications which will be developed in the rest of the book.
This subject will be developed in the next three Chapters:
Chapter 10. Drawing with Visual LISP.
Chapter 11. Selecting Entities.
Chapter 12. Modifying Entities.
