Hi @Anonymous,

Please give me more detail on what you are trying to accomplish. There are numerous ways of calculating areas and expressing the results in more than one units format.

You are welcome to attach a sample file if you believe it will help me to better understand.

There are routines around to do that.  For example, just from the Cadalyst CAD Tips website, this one, or this other one.

I measure structures.
And to calculate the area of the rooms.
Each room is a polygon.
And record it in the table.
Sometimes there are very many and difficult to calculate without mistakes.

Another method would be to place FIELDS in a TABLE.  Have those FIELDS watch your polylines.  Have the TABLE add up your FIELDS.

Hello and good evening.
Thank you for your help.
I do not know what is better.
I wanted the table next to the polygon.
Best regards

in a second thought.
If it is possible in two places.
1) polygon with a serial number.
2) in the table.
Best regards

Arealabel does all that.

Set autocad's system variable TEXTSIZE. Either from Ribbon/Annotate or use the command-line, type TEXTSIZE.
