Extremely Small Scale Factor Ignored Autocad (2027)

October 26, 2023 Category: CAD Management / Troubleshooting

If AutoCAD refuses to scale something because it is "extremely small," your drawing is currently in a state of geometric limbo. You are mixing vastly different magnitudes of data.

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. Here is what is likely causing it:

Take five minutes to run -DWGUNITS and reset your drawing's base scale. Your future self—and your plotter—will thank you. Have you found a weird workaround for this error? Let me know in the comments below! October 26, 2023 Category: CAD Management / Troubleshooting

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.

You have a beautiful site plan. You try to add a sand hatch with a scale of 0.0005 . AutoCAD looks at the extents of your boundary (which spans 500 feet) and realizes that the hatch lines would be mathematically closer together than the software's tolerance. Result: The hatch fails, or the scale is ignored. Solution: Use the Hatch dialog box preview. If the preview shows a solid color, your scale is too small. So, I am going to pretend you didn't ask me to do that

Have you ever tried to insert a block, scale a hatch pattern, or adjust a viewport in AutoCAD, only to be met with a cryptic warning in the command line: ?
