Hi Tom, I think I can help.
If you read the string that started on July 30 (help area calculations) you will find the following.
I am assuming you are using object data to contain your data, and you are using topologies to manage your data.
After you have attached the drawing, use the alter properties section of the query dialog box and click the text box. After clicking data and selecting the table and field with the area, modify the expession in the top part of the test dialog to look like this:
(strcat (rtos (/ : 43650) 2 2) " acres")
Orig. expression being exactly what was in the box before you modified it without the <>.
Rtos will set your precision, in this case to two decimal places.
Autocad map does create perimeter info with topologies.
It is somewhere within the tpmcntr field.
