By default, AutoCAD allows you to view the length of a single object in the Properties palette. If you select multiple separate lines, AutoCAD will show the count, but it will not sum up the total distance. TlenLSP automates this process. With a single command, it scans your selection and displays the exact total length in your command line, saving hours of manual addition. Common Use Cases

To keep your workflow clean and efficient, you should manage your LISP routines effectively. Here are a few best practices:

Once loaded, TlenLSP usually runs by typing a specific shortcut key in the command line. Common shortcuts often include TL or specific letters for functions. You can view the code inside the .lsp file (by opening it with Notepad) to see what command aliases are defined. Look for lines starting with (defun c:...) —the word following c: is the command you type to run the function.
