sum of distance/ length annotations
Is there a routine that sums numeric text entries please?
I have need to obtain the sum of straight numeric entries in a dwg.
Not the total number of entries but the sum of the numeric text
Egs Sum of 300.25 and 500.08 and 100.25 = 900.58
I'm just after the total as a single text entity
I Googled but the word add and sum takes one all over the place!

You can sum numeric entries in a table in Brics CAD. But I think that if you just enter text or multitext in the viewport, then CAD just recognises it as a string of text and not a numeric value.
If you are trying to sum the lengths of lines or some other geometric object then there are other ways. 
Richard,
If you type in Sum Text Autolisp into a search engine, you should get quite a few results applicable to your requirement.
One that springs to mind is: leemac.com/textcalculator.html

Many thanks to both of you for taking time to reply.
David the leemac routine looks to be it.
I did find others.
Marvellous thing Google when you ask the _appropriate _question.!Again many thanks
Howdy, Stranger!
