PRIVACY & LIMITATIONS
Coupon measurements stay local. No printer or CAD is connected.
Nominal values, measurements, target sizes, mating size, and clearance are fitted only on the current page. FitCurve does not read model files, control a 3D printer, connect to slicers, or upload measurement records.
Linear calibration aid, not a metrology certificate
The tool fits measured=a×CAD+b by ordinary least squares, shows RMSE, R², and residuals, then inverts suggested CAD dimensions. Residual median-absolute-deviation cues only suggest remeasurement and never delete points. At least three pairs and two distinct nominal values are required; values outside the fitted range are extrapolations. It does not model nonlinearity, directional anisotropy, geometry type, measurement uncertainty, repeatability, or temperature, and cannot prove manufacturability or fit safety.
Dimensions may describe an unreleased part
Refreshing or closing discards current inputs and the fit. CSV contains target finished size, suggested CAD size, and correction; reports and optional local checkpoints read the visible model summary. The page receives no model geometry, but coupon sequences, target clearance, and compensation curves may still be process-sensitive, so review them before sharing.
Advertising and local preferences
This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.
← Back to toolLocal report studio
The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.
Optional local checkpoints
Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
