area command result write text

[ekolman2003]

how I write area command result, middle of the room ?

[BIGAL]

There is two simple ways, 1st use a pline and one of its properties is the area, 2nd is use Area command pick points and retieve the Autocad variable "Area".

 

3rd more complex is to use a ray trace program just pick center of room.

 

All 3 then just write a text answer. Which do you want ?

Forum search "polyline area text" shows many interesting code.

 

Take a look here: http://www.cadtutor.net/forum/showthread.php?64428-Area-of-a-polyline&highlight=Polyline+area+text

 

One page 2 you will find a simple way that does exactly what you need.

 

Anyhow, instead of writing a simple text, i would prefer using a block which holds some attributes, e.g. area, roomnumber, usage etc.

 

By this way it's verry easy extracting room datas to table ore .csv-file, a usual task when working with floorplans.

 

You'll find many examples with the forum search terms above, many more with "ployline area block".

Have you come across Fields at all?

 

The use of a field here would allow you to set a polyline outline, and associate a piece of text with that polyline. The text would show the area. This would update as the polyline changes because the bloody client's changed their mind yet again!!

 

(If you're interested in this resaponse I can help you set it up)

I m calculate room area,with autocad "area" command. but this command Show result but not write.

After the AREA command is complete, the area value is stored in the sysvar AREA. You can retrive it with (getvar "AREA")l. -David

I see no mention of the above in any of your previous post, please make sure you post all requirements in the subject post (first one). By changing the desired outcome once a thread is being addressed is just rude... (seems like your baiting the ones assisting you then demanding further FREE development) Maybe try working on the LISP yourself to get the desired operation and result, then posting questions you may have along the way.
