This is a general question and not related to a specific bit of code.
How do you work when writing and testing a routine? My autocad doesn't "react" when I update the code with Notepad, so I have to close the file, open it again and then (load "filename") again.
I'm sure there is a better way to do this, but I've searched a bit but couldn't find (or couldn't understand) the answers. Thanks
I would strongly suggest using the development environment provided freely within AutoCAD to write, test & debug your code. This utility is known as the Visual LISP Integrated Development Environment (VLIDE).
I have written a basic introduction tutorial describing how to access & use this environment, but you can also find a wealth of information in the standard documentation provided by Autodesk.
