Issues with Donut command
Issues with Donut command
(OP)
I'm having some strange problems with the Donut command! I work with process piping and use a small donut to indicate weld dots on piping ...only been doing this 25 yr.s or so. BUT as we all know AutoCAD "up-dates" (I used the term loosely) the program, so that what has worked fine for the last decade, now has issues ...and mine are these donuts. SO I'm into my drawing and it's about 90% now, but I'm now seeing problems with the donuts I have used. Some are cut in half (that's all you now see and plots that way), then some are now "square" shape, they can no longer be picked with the center snap point, then worst case they just go to a line (always horizontal, never vertical) in the location I have put them!?? I've been looking on the internet for some help, I believe I have solved the issue with the donuts being cut in half, issues with the "OverKill" command, but that's it, I can't find anything on the square shape or the going to a line issue. Any I.T. or AutoCAD wizards out there that can give we any ideas!?? I'm working with AutoCAD 13 at present.





RE: Issues with Donut command
Since the donut is made with two semi-circular polylines, I assume you have a donut that shows only one of the segments, when you say they look "cut in half".
Is it exploded? Has it been trimmed?
Check the line type - if it's a hidden line scaled just right, it might look pretty funny.

And I haven't been able to replicate your problem in AutoCAD R14. I remember R13 - very buggy implementation on windows 95, as I recall. Not that that has much to do with your problem, not likely.
The command "OVERKILL" is not available in my R14 release. It is in my 2009 release. Bit of a mystery there.
When I try to replicate your problem in Acad 2009 I just cause other weird things to happen, not your problems.
It is possible the poly-lines that used to be your donut arcs have been converted into splines, or "curve-fit" in some way to the 2-point origins of the arcs they start with. Overkill has a tolerance (in 2009 it's called "FUZZ") which you may have inadvertently made too coarse - mine is set at 0.000001 by default.
Perhaps the scale of your drawing has extents that are dramatically larger than the detail drawing objects. In which case maybe this is just a "VIEWRES" setting that is showing you lines are blocky when nothing has actually changed at all. I set VIEWRES to 20,000 whenever possible.

Haven't encountered this one (I'm at 2012) but the square donut thing - is your VIEWRES set high enough ? I use 2000 minimum. Still, don't see the plotting thing. even at low viewres, I'd think the plot would come out right.
Whew !
Good Luck !
