Add area chart to calculated polygon

February 15, 2023

Good morning, some time ago they helped me develop a routine in which the areas of the polygons were calculated according to the data entered, for example polygons larger than 300m2, it works correctly for me, now I must add a table of areas of these lots found, identifying the apples to which they correspond as it is in the example, I hope you can help me, thank you very much.

(defun c:foo (/ a i ll n s ur)
  (cond	((and (or (setq n (getdist "\nEnter area value to check:<300> ")) (setq n 300))
	      ;; (setq c (acad_truecolordlg 1))
	      (setq s (ssget '((0 . "LWPOLYLINE") (8 . "living"))))
	      (setq i 0)
	 )
	 (foreach e (vl-remove-if 'listp (mapcar 'cadr (ssnamex s)))
	   (if (>= (setq a (vlax-curve-getarea e)) n)
	     (progn (entmake (append (entget e) '((8 . "LIVING-AREA") (62 . 1))))
		    (vla-getboundingbox (vlax-ename->vla-object e) 'll 'ur)
		    (setq ll (vlax-safearray->list ll))
		    (setq ur (vlax-safearray->list ur))
		    (setq ll (mapcar '/ (mapcar '+ ll ur) '(2 2 2)))
		    (setq i (+ i a))
		    (entmake (list '(0 . "TEXT")
				   '(100 . "AcDbEntity")
				   '(67 . 0)
				   '(8 . "LIVING-AREA")
				   '(62 . 1)
				   '(100 . "AcDbText")
				   (cons 10 ll)
				   '(40 . 1.5)
				   (cons 1 (vl-princ-to-string a))
				   '(50 . 0.0)
				   '(41 . 1.0)
				   '(51 . 0.0)
				   '(71 . 0)
				   '(72 . 1)
				   (cons 11 ll)
				   '(100 . "AcDbText")
				   '(73 . 2)
			     )
		    )
	     )
	     ;; (ssdel e s)
	   )
	 )
	 ;; Print total to command line
	 (print i)
	 (print (sslength s))
	 ;;(sssetfirst nil s)
	)
  )
  (princ)
)

In this routine the calculation of areas is done to 3 decimal places, it could be changed to 2 decimal places

Hi

Try

Change

(cons 1 (vl-princ-to-string a))

With

(cons 1 (rtos a 2 2))

Not tested, but see if you can use it... If something's wrong, I suspect at command tokens specified for (command) inputs - here (exe (list "_.command" "token1" "token2" ...))

Hi Marko the error occurs at this line

(foreach data datalst
        (setvar (quote cecolor) (nth 3 data));; error at this line 
        (exe (list "_.TEXT" "" "_non" pt room ""))
        (exe (list "_.TEXT" "" "_non" (polar pt (* 1.5 pi) 0.5) (strcat area " m²" "")))
      )

data hold

I did it at command line

Try (setvar 'cecolor (rtos (nth 3 data) 2 0))

Also this line have to apply rtos

and when ask to select the point to set the table

Also this line have to apply rtos

 (setvar (quote cecolor) (rtos (nth 3 data)2 0));; aplyed RTOS to color as NUMBER
        (exe (list "_.TEXT" "" "_non" pt room ""))
        (exe (list "_.TEXT" "" "_non" (polar pt (* 1.5 pi) 0.5) (strcat (rtos area 2 4) " m²" ""))); applied RTOS to area

Hi, when selecting the elements and clicking the insertion point of the box, the result is _non

This was the code that helped me at the time and it works perfectly, but now I have to generate a table of areas with the blocks to which the calculated lots that are greater than 300m2 correspond.

(defun c:foo (/ a i ll n s ur)
  (cond	((and (or (setq n (getdist "\nEnter area value to check:<300> ")) (setq n 300))
	      ;; (setq c (acad_truecolordlg 1))
	      (setq s (ssget '((0 . "LWPOLYLINE") (8 . "living"))))
	      (setq i 0)
	 )
	 (foreach e (vl-remove-if 'listp (mapcar 'cadr (ssnamex s)))
	   (if (>= (setq a (vlax-curve-getarea e)) n)
	     (progn (entmake (append (entget e) '((8 . "LIVING-AREA") (62 . 1))))
		    (vla-getboundingbox (vlax-ename->vla-object e) 'll 'ur)
		    (setq ll (vlax-safearray->list ll))
		    (setq ur (vlax-safearray->list ur))
		    (setq ll (mapcar '/ (mapcar '+ ll ur) '(2 2 2)))
		    (setq i (+ i a))
		    (entmake (list '(0 . "TEXT")
				   '(100 . "AcDbEntity")
				   '(67 . 0)
				   '(8 . "LIVING-AREA")
				   '(62 . 1)
				   '(100 . "AcDbText")
				   (cons 10 ll)
				   '(40 . 1.5)
				   (cons 1 (vl-princ-to-string a))
				   '(50 . 0.0)
				   '(41 . 1.0)
				   '(51 . 0.0)
				   '(71 . 0)
				   '(72 . 1)
				   (cons 11 ll)
				   '(100 . "AcDbText")
				   '(73 . 2)
			     )
		    )
	     )
	     ;; (ssdel e s)
	   )
	 )
	 ;; Print total to command line
	 (print i)
	 (print (sslength s))
	 ;;(sssetfirst nil s)

Hello, yes I see that it is very interesting but I get this error, thank you very much for the contribution I would like it to work correctly and that is why it is my doubt to know where the error is

Select boundary LWPOLYLINE(s) on Layer(s) representing names of rooms of objects drawing plan...

Select objects:

Test it again... I've updated it once again... Please note that you must have boundary LWPOLYLINE(S) in corresponding Layer(s) representing various room(s) specification(s) - each Layer must have different color to become distinguished with each other... Added TOTAL row to TABLE...

Just saw your DWG...

You have parcel instead of room, so I've changed my code accordingly... If you find it useful, please give it a kudo, or solution so that we know that your request founded adequate answer...

It doesn't occur on my PC(s)... All my CAD(s) don't error at that place - it is my template sub for writing new stuff more reliably... Why would variable CLAYER reject "0" - it must be that you removed layer "0" which is default one... Although I read that "0" Layer can't be removed, I've seen during my carrier that on one DWG it didn't exist... Please return back Layer "0" and start routine exactly from that Layer... One more thing - my code is made for many different Layer(s) colored differently for DWG's far more descriptive than OP's posted one... Still, it didn't break on my BricsCAD V23, AutoCAD 2022 and BricsCAD V21...

Hi Marko , the problem becomes because at the polygons.dwg . layer is freeze

I noticed it while testing the OP lsp
