Theoretical and actual Point X and Y differeces!

October 19, 2017

I need autolisp that can calculate differences between theoretical point and actualpoint and draw arrows and put x;y values.

NB! Look attachment!

You may want to explain what you mean by 'theoretical point' and 'actual point'.

Actually these are two point and i need differences between points! Autolisp draw arrows and value x;y!

Subtract your x's and y's?

(defun c:foo (/ s)
 (if (and (setq s (ssget '((0 . "point")))) (= 2 (sslength s)))
   (progn (setq s (mapcar '(lambda (x) (cdr (assoc 10 (entget x))))
		   (vl-remove-if 'listp (mapcar 'cadr (ssnamex s)))
	   )
   )
   (alert (vl-princ-to-string (mapcar 'abs (mapcar '- (car s) (cadr s)))))
   )
 )
 (princ)
)

Something like this?

(defun c:CADTUTOR ( / )
(setq point1 (getpoint "Select first point: "))
(setq point2 (getpoint "Select second point: "))
(command "_DIMLINEAR" point1 point2 "H" point2)
(command "_DIMLINEAR" point1 point2 "V" point2)
(princ)
)

Way to go for lots of points is make a selection set of real points make a selection set of theorectical, you can then check how close the points are using a tolerance, the choice is your then x1,y1 -> x2,y2 = dist to file, on screen or dim like Aftertouch. Also did not find's !

This is almost that i need but ... can you edit code like this: autolisp draw arrows and differences (mm) end of arrow!

See attachment above!

Thanks!

Rather than a dim look into a leader, pt3 would be an offset from pt2 at angle pt1-pt2

(command "leader" pt1 pt2 pt3 "a" diff "")

Hi,

This is olmosta done but, is it possible edit code like this: activ osnap stay ON and number is always same direction!

Best,
