Read the text file first. The files you want are tip1745a & 1745B. After extracing them rename them sol_spring & 3dspiral respectively. Place them in your ACAD support folder. Insure ACAD searchpath has this directory listed. Load lsp routines and you are good to go. Run "3dspiral". That will get you either a straight or tapered spiral if you want. You can then run "sol_spring" if you want to extrude a round or square solid 3d spring. Hope this is what you wanted.
