Hi All, I need some help here. I'v been using a autolisp (obtained from a friend) to calculate floor area with AutoCAD 2007. However recently I've upgraded my AutoCAD to 2013 and I realised the lisp coudn't function completely. I've attached the lisp file here, really hope someone can help to rectify so that it works for AutoCAD 2013.

Fyi I knows nothing about writting lisp code. Many thanks in advance! (not sure why this code looks so massive compared to others.) To share with those who may be interested, this lisp allows you to select multiple polylines (eg. Floor area), followed by select those polylines representing regions to be subtracted (eg. Void area), it will help you tabulate all the polyline parcels (floor areas subtract floor void) with end result and with labels for each parcel.

If you only calculate area of Polylines you can use my code. It display area of all Polylines seperate after layer. I´m very thankfully for all feedbacks to can do it better.

Hi Wishbonesr and cadplayer, thanks for your comments and help. I've seen some of those links before, esp. From Lee Mac. They are awesome.

However I need the end result to be in this specific format as it is for submission purpose. If you try using the autolisp that i attached earlier, you can find out the type of format I am looking at. Some experts out there pls help~ Here's a more detail description of the autolisp function. Situation: You have a number of big closed polylines (Floor Areas). Within each of these Green Areas there is a few small closed polylines (Void Areas).

Function of the autolisp: - it will first ask you specify scale of drawing (eg. You key in 50, 100 or 200 etc, it'll adjust the text size accordingly). - Select Floor Areas (you select the big closed polylines) - Any Void Areas? Yes) - Select Void Areas (you select the small closed polylines) - Pick insertion point for tabulation (you pick a point on empty space) ** The end result tabulation is as per shown in the screen shot below. It will also gives a label (eg. A, B, C.) and the area figure inside each polyline area.

The above will help save a lot of time as without this lisp we'll have to do all the above manually. And repeatedly. EXperts out there your big help is greatly appreciated.

Spoke with my old man about this one. He told me that it was kinda common for some lispers (pre vlisp-compile days)to run a program on their routines to make it incredibly difficult to modify or debug. They then keep a copy of the original. He called it, 'one form of job security'. With that being learned, I decided to look harder, and had to stop myself when I started to optimize. I will say up front, that I make no claim to any portion of this code, and that all credit goes to Gildred. Went so far as to mask all functions with a prefix, just in case of conflict; And nested as many as I could without seriously modifying.

The problem, was in fact the write location for the temporary files it uses. It has been fixed, and should work on any system. I was off on the number of lines this program should have been.

Wound up being 940 without comments. Tested ATAB only.

Lisp to Display the Area of Polylines in AutoCAD FreeCADTipsAndTricks is back this week with another excellent lisp routine for AutoCAD. Download Free Lisp Areaon.lsp. Areaon.lsp is a LISP routine that will display the entire area of a selection set of objects. This can be supportive if you want to compute the total area of multiple closed polylines, for example.
