Calculating a perimeter of an object in Illustrator.

[g...@graphix.co.uk]

Does anybody have the means to import an Illustrator file to another
package which would calculate the objects perimeter distance ?

I have a 'kidney' like shape, one path, and need to calculate accurately
the outside perimeter measurement (or circumfrance) of that irregular
shape.

Any Ideas ?

2nd try. Hopefully more legible.
AutoCAD is pretty adept at calculating the perimeter and area of an irregular
shape. Save the shape as .eps (ver 4.0 or thereabouts), then import it into
AutoCAD with the PSIN command. Just a little manipulation and you can
have your answer to just about as many decimal places as you might like.

well... this may be more complicated than you are after but it'll work
for you. There's a freeware program called NIH-Image that will do all
kinds of measurement tasks, including lengths and perimeters. You can
download the Mac version at:

http://rsb.info.nih.gov/nih-image/

The Windows version is at:
http://www.scioncorp.com/

You'll have to export your Illustrator image into TIFF format or
convert it somehow into a bitmap for NIH Image to recognize it.

Open in Image, and got to Analyze>Measure. Under Analyze>Options you
can pick all the stuff you want measured, including
distance/perimeter.

This program is great for doing measurements of all kinds. It is not
so good for making selections. It has the usual direct selection
tools like you might find in photoshop, but tools and approaches such
as magic wands, alpha channels, masking, etc. are severely limited, if
not missing altogether. Drawing around curves by hand can be
cumbersome -- there is a magic wand tool that works in binary mode so
you could conceivably work out a way do selections automatically with
the wand, depending on the complexity of your backgrounds. Maybe you
could fill your 'kidney' shapes with black for the purposes of
measurement in Image. It should work pretty well, now that I think
about it. And you can't beat the price.

Let me know if you have any questions.

But that only lists the diameter and not the perimeter.

There is a plugin for Illustrator called CadTools from HotDoor
it can calculate the area and the perimeter of an object in Illustrator.

Well, first, I think you meant "circumference," not "perimeter."
Perimeter is for things that have sides.

But leaving the linguistics aside, just multiply the diameter by
3.1416 to find the circumference of the circle.

And having said that, the original poster said he had a kidney shaped
object, where a circle would not really work anyway. If I had a kidney
shaped thing to calculate, I'd stop by the office of a surveyor I
know. He'd run it through a program he uses and I'd have the answer in
a flash. (No, I don't know the name of the program, unfortunately.)

Too bad Adobe didn't include a perimeter parameter.

Sorry. Couldn't resist.
