Moving an edge on a geometry, far from origo

[wim (Wim Dekeyser)]

@GBirde

Is there a way to solve this?

As was said already, you can either move closer to the origin or use meters.
What is going on here is that the math in Rhino 5 uses double-precision accuracy for its operations on geometry but the display mesh is only single-precision. This has been changed for Rhino 6.

If you search a bit here on the forum you will find a lot of threads on this. Just one example:

Bug? Rhino isn't accurate far from origin

No, it does not work like fixed number of digits. A floating point number is represented as s*1.m*2^e where s is the sign bit, m is the mantissa and e is the exponent. Together there are 32 (single precision) or 64 (double precision) bits to store the sign, mantissa and exponent. This way, an enormous range of numbers is representable, but the gap between the representable numbers becomes larger and larger as number size increases. This is the origin of the inaccuracies. Representable numbers, …
