All custom Lisp Routines from Rayburn Drafting have been designed to standardize and automate the process of producing residential house plans. Their aim is to decrease plan production time which allows more time for creativity and design! They have been evolving for many years and were originally written to be used in conjunction with a comprehensive menu system, called Speed Menu, which is still used today primarily to insert blocks and to launch Lisp Routines.
Each Lisp Routine showcased in this site is used daily by hundreds of design professionals all over the world and they all have been tested in real working environments. These routines will give your drawings a polished look, make drawing house plans quicker and easier, and keep you up-to-date with today's building and drafting standards.
