Need help with LISP to create thread

[stapelbergp675461]

Good day all.

I have only started with LISP programming 2 days ago, so I am very new to this.

I have the following situation:
I need the LISP to create a circle and extrude it to the users inputs, then create a helix around the same cylinder, then sweep a user defined shape(profile) along the helix.
once that is done, the helix needs to be subtracted from the cylinder.

I have the following code:

(defun c:circ ( / bp rad height height1 turns)
    (setq bp (getpoint "pick basepoint:"))
    (setq rad (getdist "\nenter radius:"))
    (setq height (getdist "specify height:"))
    (setq height1 (getdist "specify height:"))
    (setq turns (getint "specify number of turns:"))
    
    (command "_cylinder" bp rad height)
    (setq cyl (entlast))
    (command "_helix" bp rad rad height1 turns)
    (setq hel (entlast))


  
)

The user must also be able to input the amount of turns on the helix.

Would appreciate all the help I can get.

The fact that you're so new to LISP, and you've included code tags in your first post, I just wanted to extend a very warm welcome to AUGI!

I'm confident that someone will come along shortly in an effort to help.

Cheers
