Where layer transparency is concerned, this may be of interest - https://www.theswamp.org/index.php?topic=52473.msg574001#msg574001

In numerical functions, this: ;; TEXT ((equal (cdr (assoc 0 edata)) "TEXT") (setq val (cdr (assoc 1 edata)))) ;; MTEXT ((equal (cdr (assoc 0 edata)) "MTEXT") (setq str1 (cdr (assoc 1 edata))) (setq str3 (cdr (assoc 3 edata))) (setq val (strcat str1 str3)) ) could probably be just ;; TEXT ((equal (cdr (assoc 0 edata)) "*TEXT") (setq val (cdr (assoc 1 edata))) ) reason being in text. assoc 3 comes into things if the text string is over 256 characters long... which is a very very big number.

Nikon, you forgot to add open and closing brackets for v1 and v2... Like I said it should be : (atof v1) and (atof v2)...

After the layer is created add this line to set 30% transparency: (entmod (append (entget (tblobjname "layer" lay)) '((-3("AcCmTransparency" (1071 . 33554610))))))

you may also consider using a simple block first , just a rectangle , that way routine might run faster. After you're done , replace simple blocks with actual 3D chairs.

Whereever in the code occurs v1 or v2, change them to (atof v1) and (atof v2)...

Since it's not a text string and you want to concatenate it with '(cdr (assoc 1 edata))', it gets 'indigestible' and 'erupts': stringp nil'

You need to use Code Tags (<> in the editor toolbar) for your Code, not Quote Tags!

Hey @PGia, Try the modified code from last post. I updated code about an 1 hour ago. Maybe you tried unupdated version.

Just wondering how many churches you lay out like this. If it is just the one I would be tempted to fill the rows with a basic polar array, probably quicker than writing and testing a LISP. If you are doing this multiple times then LISP makes sense though

Hi @PGia Can you attach a larger drawing? I need to run some tests.

Notice: It will only concate the label/text value of closed polyline with an Area of that closed polyline, for opened polylines, nothing is going to happen. Best regards.
