Automatic number dimension

Recommended Posts

Hi When I want to dimension for the wall quantity, I want it to number each dimension. Is something like this possible? But it needs automatic numbering when dimensioning. Also, if you have any add-ons to share for the wall footage, I would like to receive them. And it would be much nicer if I could export them to excel. Thank you for your help

Q1 yes could be done by using a lisp that adds the Dim x as the dimension override string "Dim 22 <>"

 

Q2 measure walls yes but it depends totally on how you draw the walls.

Q3 yes 2 ways do a CSV file or write direct to excel a bit harder.

 

Lets start Q1 I will let you wrap it as  a defun, same as if you don't like dim position then you need to google about changing dim text position.

 

(setq x (getint "\nEnter start number"))
(while (setq pt1 (getpoint "\nPick Pt1 or Enter to exit"))
(command "dimaligned" pt1 (getpoint "\nPt2") "T" (strcat "Dim " (rtos x 2 0) "\n <>") (getpoint "\nPick offset"))
(setq x (1+ x))
)

That's quite a complicated way of doing what BigAl did in 5 lines.....

 

My usual way of going is fewer simpler LISPs to remember but have them more versatile for many cases. So in this case using BigAl which will dimension lines and polylines and using the drawing set up for dimension style would be the way I would go as opposed to having a LISP just to dimension polylines with a defined dimension style, and by inference another LISP for lines, and another for gaps,  and another if I want to use a different dimension style (different clients for example)

Hi 

hosneyalaa

I want it to be dimensioned by marking, not this way. So when I mark the beginning and the end, it will be numbered sequentially. When I exit the command and want to continue again, the numbering will continue where I left off. thanks

Give this program a try and let me know. :)

Mr Bigal:

Thank you for your understanding Similar available but only transfers dimensions Let me transfer the naming that I want in order. thank you for your help
