My work involves a lot of measurements in order to get my quantities off the drawings and make the estimations I need. For this work I only work with AutoCAD. I strongly believe that it is more than enough as it comes with lots of good and handy tools to do the job. Although, some things still “missing” or at least it cannot cover anyone’s demand for commands.
The use of LISP and the creation of custom commands from scratch or manipulating/using what others have created can easily solve this “problem”.
