Solution: Always verify UNITS before you start. Use INSUNITS to let AutoCAD handle scaling automatically. extremely small scale factor ignored autocad

Let’s dig into why this error happens, why ignoring it is a bad idea, and how to fix the root cause. AutoCAD operates on a double-precision floating-point system. In human terms, that means it can handle very large numbers (think miles of pipeline) and very small numbers (think microns of a chip). However, AutoCAD has a practical threshold.

When you see "Extremely small scale factor ignored," AutoCAD is saying: "You asked me to scale something by 0.00000001, but my internal tolerance thinks that number is essentially zero. So, I am going to pretend you didn't ask me to do that." This error doesn't happen in a vacuum. It is almost always a symptom of a larger drafting sin.
