Hi guys!
I've wrote this lisp in order to draw these circles + lines in a fasted way.
As you can see it doesn't work very good with the vertical edge of 30cm, but it works if I put 60cm..
The program asks me the following:
1. number of lines
2. number of circles for each line
3. 2 points where to draw them
4. side of the line I've just draw with the 2 points
How can I handle non vertical/horizontal lines?Code:(defun C:pu (/ linea) (setq n1 (getint "\nQuante legature? ") ;how many lines n2 (getint "\nQuante file? ")) ; how many circles for each line (command "_Line" pause pause "") (setq linea (entlast)) ;(command "_divide" linea (* 2 n1)) (setq p1 (cdr (assoc 10 (entget linea))) p2 (cdr (assoc 11 (entget linea))) dist (/ (distance p1 p2) (* 2 n1))) (entdel linea) (setq ref (getpoint)) (setq passo 0.16 dist1 0.08 n 0 j 1 ) (IF (> (nth 0 p1) (nth 0 p2)) (setq swap p2 p2 p1 p1 swap) ) (IF (> (nth 1 p1) (nth 1 p2)) (setq swap p2 p2 p1 p1 swap) ) ;Horizzontal (COND ((= (fix (nth 1 p1)) (fix (nth 1 p2))) (IF (< (nth 1 ref) (nth 1 p1)) (setq passo (* passo -1) dist1 (* dist1 -1) ) ) (while (< n n1 ) (setq i 1) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) (* j dist)) (+ (nth 1 p1) dist1) (nth 2 p1))) (cons 40 0.035) (cons 62 3) ) ) (while (< i n2) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) (* j dist)) (+ (nth 1 p1) dist1 (* i passo)) (nth 2 p1))) (cons 40 0.035) (cons 62 3) ) ) (setq i (+ i 1)) ) (entmake (list (cons 0 "LINE") (Cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) (* j dist)) (+ (nth 1 p1) dist1) (nth 2 p1))) (cons 11 (list (+ (nth 0 p1) (* j dist)) (+ (nth 1 p1) dist1 (* (- i 1) passo)) (nth 2 p1))) (cons 62 3) ) ) (setq j (+ j 2) n (+ n 1)) ) ) ;VERTICAL ((= (fix (nth 0 p1)) (fix (nth 0 p2))) (IF (< (nth 0 ref) (nth 0 p1)) (setq passo (* passo -1) dist1 (* dist1 -1) ) ) (while (< n n1 ) (setq i 1) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) dist1) (+ (nth 1 p1) (* j dist)) (nth 2 p1))) (cons 40 0.035) (cons 62 3) ) ) (while (< i n2) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) dist1 (* i passo)) (+ (nth 1 p1) (* j dist)) (nth 2 p1))) (cons 40 0.035) (cons 62 3) ) ) (setq i (+ i 1)) ) (entmake (list (cons 0 "LINE") (Cons 8 "SCHÖCK_BOLE") (cons 10 (list (+ (nth 0 p1) dist1) (+ (nth 1 p1) (* j dist)) (nth 2 p1))) (cons 11 (list (+ (nth 0 p1) dist1 (* (- i 1) passo)) (+ (nth 1 p1) (* j dist)) (nth 2 p1))) (cons 62 3) ) ) (setq j (+ j 2) n (+ n 1)) ) ) ) )
How can I draw in the corner as well?
Thanks!

With Mathematics there is the possibility of perfect rigour, so why settle for less?
One suggestion in your code you repeat the entmake multiple times this could exist maybe twice line,circle as you can use a defun that you pass the variables to, this is a standard type of thing in programming to not write bits of code repeatedly.
Code:(defun ML:Makeline (lay pt1 pt2 / ) (entmake (list (cons 0 "LINE") (Cons 8 Lay) (cons 10 pt1) (cons 11 pt2) (cons 62 3) ) ) ) ; put at start (setq clay "SCHÖCK_BOLE") ; example (setq p1 (list (+ (nth 0 p1) dist1) (+ (nth 1 p1) (* j dist)) (nth 2 p1))) (setq p2 (list (+ (nth 0 p1) (* j dist)) (+ (nth 1 p1) dist1 (* (- i 1) passo)) (nth 2 p1))) (ML:Makeline clay p1 p2)

Thank you guys for your help!
Yes I should learn to code a little bit better my code looks always like a mess..
I'll try to fix it!
See you soon!

Hello guys!!
Today I had some time to continue this project!
I've totally rewrote the code:
I'm very proud of thatCode:(defun c:test (/) (setq n1 2 n2 3 diam 0.035 dist_y 0.10 ) (command "_Line" pause pause "") (SETQ ref (GETPOINT) linea (ENTLAST) p1 (CDR (ASSOC 10 (ENTGET linea))) p2 (CDR (ASSOC 11 (ENTGET linea))) dist_x (/ (DISTANCE p1 p2) (* 2 n1)) ang (angle p1 p2) ) (entdel linea) ;inversione in funzione di ref (setq inv 1 k 1 ) (repeat n1 ;direzione X (setq j 1) (ML:Makeline "SCHÖCK_BOLE" (polar (polar p1 ang (* k dist_x)) (+ ang (* inv (/ pi 2))) (* 1 dist_y)) (polar (polar p1 ang (* k dist_x)) (+ ang (* inv (/ pi 2))) (* (- (* n2 2) 1) dist_y)) ) (repeat n2 ;direzione Y ; J=1;3;5 etc (setq pnt (polar (polar p1 ang (* k dist_x)) (+ ang (* inv (/ pi 2))) (* j dist_y) )) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 pnt) (cons 40 diam) (cons 62 3) ) ) (setq j (+ j 2)) ) (setq k (+ k 2)) ) ) (defun ML:Makeline (lay pt1 pt2 / ) (entmake (list (cons 0 "LINE") (Cons 8 Lay) (cons 10 pt1) (cons 11 pt2) (cons 62 3) ) ) )
Can you give me an hint please?
There is a REF point at the beginning.. I want to use this point to say the direction of my circles+lines instead of going always counterclockwise for external and clockwise for internal.. How can I check it? the INV goes "-1" or "+1" to consider that.
Do you think I need to write a new function to draw in the 45° direction for the edges?
Thanks for your help
Dennis
EDIT: maybe something like that but I don't like it very much.. The original idea is to divide the 90 degree in half (one line+circle at 45°) and in 3 parts (2 lines+circles at 30°). Any suggestion?
Code:(defun legatura_diagonale (a / j k) (setq j 1 k 1) (repeat n2 ;direzione Y ; J=1;3;5 etc (setq pnt (polar p1 (+ ang (* inv a)) (* j dist_y) )) (Entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 pnt) (cons 40 diam) (cons 62 3) ) ) (setq j (+ j 2)) ) (ML:Makeline "SCHÖCK_BOLE" (polar p1 (+ ang (* inv a)) (* 1 dist_y)) (polar p1 (+ ang (* inv a)) (* (- (* n2 2) 1) dist_y)) ) )

Hi,
I tried not to change the way of coding you did so hope it is clear enough to you to learn from.
Code:(defun c:test (/ gap clr diam len p1 p2 p3 ang rot dis pcs div lft a b) (setq gap 2 crl 3 diam 0.035 len 0.40 ) (if (and (setq p1 (getpoint "\nSpecify start point :")) (setq p2 (getpoint "\nNext point :" p1)) (setq p3 (getpoint "\nSpecify direction of Lines & Circles :")) (setq ang (angle p1 p2)) ) (progn (setq rot (+ ang (* pi (if (minusp (sin (- (angle p1 p2) (angle p1 p3)))) 0.5 1.5))) dis (/ (distance p1 p2) (1+ gap)) pcs dis ) (repeat gap (ml:makeline "SCHÖCK_BOLE" (setq a (polar p1 ang pcs)) (setq b (polar a rot len))) (setq div (/ (distance a b) (1+ crl)) lft div ) (repeat crl (ml:makecircle (polar a rot lft) diam) (setq lft (+ lft div)) ) (setq pcs (+ pcs dis) ) ) ) ) (princ) ) (defun ml:makecircle (pnt diam) (entmake (list (cons 0 "CIRCLE") (cons 8 "SCHÖCK_BOLE") (cons 10 pnt) (cons 40 diam) (cons 62 3) ) ) ) (defun ml:makeline (lay pt1 pt2) (entmake (list (cons 0 "LINE") (cons 8 lay) (cons 10 pt1) (cons 11 pt2) (cons 62 3) ) ) )

Maybe next version if the rectang is a pline then you only need imply Inside or out or none. No need to pick points. Look at this it has the co-ords of the corner point so can do the pt1-pt2 etc
Code:; pline co-ords example ; By Alan H (defun getcoords (ent) (vlax-safearray->list (vlax-variant-value (vlax-get-property obj "Coordinates" ) ) ) ) (defun co-ords2xy () ; convert now to a list of xy as co-ords are x y x y x y if 3d x y z x y z (setq len (length co-ords)) (if (= (vla-get-objectname obj) "AcDbLwpolyline") (setq numb (/ len 2)) ; even and odd check required (setq I 0) (repeat numb (setq xy (list (nth i co-ords)(nth (+ I 1) co-ords) )) ; odd (setq xy (list (nth i co-ords)(nth (+ I 1) co-ords)(nth (+ I 2) co-ords) )) (setq co-ordsxy (cons xy co-ordsxy)) (setq I (+ I 2)) ) ) ; program starts here (setq obj (vlax-ename->vla-object (car (entsel "\nplease pick pline")))) (setq co-ords (getcoords obj)) (co-ords2xy) ; list of 2d points making pline ; co-ordsxy holds the list of points ((X Y)(X Y)...
