Extremely Small Scale Factor: Ignored Autocad ((free))

Computers do not store decimal numbers perfectly. 1/10 (0.1) in binary is a repeating fraction, like 1/3 is in decimal. When you scale an object by 0.0001 , AutoCAD isn't multiplying by one number; it's recalculating every vertex coordinate.

You import a chip layout (micrometers) into a site plan (kilometers). To make the chip visible, you scale it up by 1e9 . Later, you need to scale a detail down by 1e-9 to export it back. AutoCAD ignores the downscale because the original geometry lost precision during the first scale. extremely small scale factor ignored autocad

Next time you type 0.00001 and nothing happens, don't curse the software. Zoom in, check your units, and scale smarter—not smaller. Computers do not store decimal numbers perfectly

AutoCAD does not "ignore" extremely small scale factors out of laziness or poor programming. It ignores them because geometry smaller than 1e-8 units can no longer be meaningfully represented in a binary coordinate system. That object has fallen through the cracks of digital reality. You import a chip layout (micrometers) into a
