Anyone know of a way to add a thickness or width to a circle? Basically I want to be able to edit the circle the way I can a PLine and view the width of it on screen. Any ideas?
Thanks

Look at DONUT in the help menu.

if the circle is an arc ( break the circle ) you can change the start angle to 0.0001 and the end angle to 0. Then you can use pedit to turn it in to a pline and use a width.

There's a lisp routine floating around by Jason Piercey that converts circles to polylines. I found it posted somewhere around here or the autodesk discussion boards. May also have been on Cadalyst or something. I don't want to post it for copywright reasons but I'm sure he offered it up somewhere. From there you simply use pedit.

Might not be the best way, but another option is to just draw a pline over the existing circle and add a width to that. Then either erase the circle or leave it there with two objects on top each other.

Hi

Check out CIRCLE2PL.VLX from DotSoft Free Stuff (http://www.dotsoft.com/freestuff.htm)

Have a good one, Mike

Funny, it does what I suggested but they break the circle in two pieces at 90 and 270 degrees before they convert to a pline.
I suggested a tiny tiny angle, and it works to.

If you break in one place you must, in theory, leave a gap - no matter how small. Breaking it in two means that together they can complete the 360%%d.
I say "in theory" because I know I have in the past managed to create a full 360%%d arc but I can't remember how.

With map you can use the drawing cleanup under the tools menu to convert circles to plines.

What happens when you explode one of those, one circle, two arcs or... ?

Yes, that is true.

...in the past managed to create a full 360%%d arc but I can't remember how.Yes, in older versions you could even create arcs running around more then 360 %%d.

Logically you would think it would revert to the original object.
How often is the program that logical?
It becomes 2 arcs.

No, it is not abut program logical, it is abut how to treat AutoCAD objects
can a circle becomes to a string ? In my knowledge no.

As Maveric came back with, the Donut is nothing more than a circle with width. Check the properties, it wont even call it a donut. Why cant the command help spell this out?

That's 'cause it's not a circle, but a circular pline to which you can assign a width.

You can also try creating the circle as a polygon of appropriate size, then use pedit on the polyline. Select the polyline, enter fit and the circle will be created. You can then change the line width
