View Full Version : problem with arc in 2008???
8th Jan 2008, 11:30 pm
:x I am only now venturing into 2008. When I draw an arc using start-end-radius, I get a response: Start and end angle must differ.
*Invalid* This is patently not true. I can draw the exact same arc in 2004. I can import that arc into 2008, and it will lay exactly where I wanted the arc in the first place. If I list the arc, the start and end angles are different.

Perhaps you could post an example of what you are tying to do.

Yikes: can I post a drawing? I am trying to draw an arc from point a to point b, with a radius of 600. Thanks.

Specify start point of arc or [center]:<Point A>
Specify second point of arc or [Center/End]: e
Specify end point of arc:<Point B>
Specify center point of arc or [Angle/Direction/Radius]: r Specify radius of

Thanks for the example mahahaavaaha. And yes, that is exactly what I meant.

Sinc, over in the Autocad.com user group came up with the solution for me. Here is a copy of Sinc's response:
I have hit a bug with the Arc command where it sometimes gets confused, depending on where the cursor is left on-screen in relation to the arc. I know, it seems ridiculous that the location of the cursor should interfere with typing the radius on the keyboard, but sometimes it does. This problem was introduced in 2007, I think.
At one point, I think I had at least somewhat identified the exact circumstances under which this problem occurs, but I cannot remember the details any more. Do you have DYN on? It might be one of those things that only happens if DYN is turned on.
Other than that, try putting the crosshairs in different places on the screen before you enter the radius, and see if you can find a spot where it will accept the input.

Sorry to revive an old thread, but I'm going to anyway. It appears that the position of the cursor on the screen does in fact affect the arc.
To remedy this, you have to place the cursor in such a spot that the arc will actually appear on screen. If the arc doesn't appear, you get the error message that Space Mouse posted.

I wonder if this bug has been mentioned to Autodesk?
I ran into this problem not long after this post, so I knew the remedy. :D
