Angle Offset Errors in AutoCAD 2010

Happy New Year to you all.

We have a issue in our design department with 2010 where if we draw lines, use offset, rotate etc, when you select the properties if the line etc, the angle or dimemsion is for example 1.0000000001. or angle 359.9999999999. Some of the lines have been drawn from the start again but stil have issues!!!!!

Does anybody know why?

Cheers

Lets see... the sin of 0.0000000001 = 0.0000000000017545

(approx).

that amounts to a deflection of 0.000000009213 feet over a mile (approx.)

What kind of tolerances are you working with?

Maybe you ought to set your precision lower in Units

(* 5280 (sin (* pi (/ 0.0000000001 180))))

Unless you're building a new, longer, particle accelerator does it make a difference if you're 0.0000000001 off?

Lest an assumption be made about a careless, sloppy Autodesk: With double precision floating point operations, binary to decimal mapping issue arise with numbers of a large WholeNumberFractionalNumber spread. It shows up in all manner of software, Cad, Spreadsheets, etc.

Happy New Year to you all.

See this posted over on the AUGI forums.

ALL of you are missing the point. It didn't happen in previous versions of AutoCAD!!!!!

I think most of our responses were elaborating on the “point”. I don’t have 2010, and it may have a different tolerance setting, but all versions of AutoCAD (and other software) contend with the same problem.

I think your specific issue - associated with that point - is resolved by the suggestion made in post #2

Let's not over react OK?

You mention using 2010. Has Update 1 been applied?

Are you on Subscription?

May I ask why this is so critical? Your statement "...I still have issues" has peaked my curiousity. What are you drawing that requires this level of accuracy and can it/will it be built to it?
