Area and Perimeter extraction

[Rhincodon]

G'day, I do alot of calculations using the area and perimeter of rooms so i'm trying to produce a lisp to spped up the process. My initial idea was to draw a polyline around the room and then create 2 attributes: area and perimeter, and use the field function to define the default values. Then make the attributes into a block with a block name that could be manually entered as the room name. I'd then extract all this info to excel using attribute extraction. This process works perfectly I just don't know how to write it in code. Any help would be greatly appreciated.

Thanks but its not quite what i'm looking for. That inserts it as MText, I'm after a block insert so I can extract the information to make a room by room list. Some thing kind of like this....

Only thing that needs to change is that I would like to show a "Room Name" and a "Perimeter" attribute in the same block, but I can't quite get it to work.

It should have been enough to get you started. :wink:
