Saving, sharing & exporting — MEP Tools

Save and autosave, copying a share link, and the difference between free Print and Pro Export PDF.

This page covers the File-menu and action-rail rows specific to this calculator. For how saving, autosave and drafts work across the whole app, see Projects & saving and Save status & unsaved work; for what each plan unlocks, see Plans & payments.

Save, Autosave, Save As, Rename

• Save (Ctrl/Cmd + S, rail, or File menu) stores the current document as a project. You must be signed in; a guest or unverified account sees a prompt instead of saving:

  • Signed out: "Sign in to keep this calculation" — your inputs stay on this device until you create an account.
  • Signed in but unverified: "Verify your email to save" — the prompt offers a retry once you've verified.

  See Projects & saving for what happens to your work before you sign in.

• Autosave toggles on/off from the File menu.

• Save As and Rename manage named copies of the project, same as every other tool — see Projects & saving.

• New discards the active project and returns to a blank document (it does not reload the worked example).

Share

Share (rail button) or Copy share link (File menu) copies a URL that encodes your current inputs — every stage, including the fitting schedule (label and K per row) and the units you picked. It does not encode a result: whoever opens the link sees your inputs restored with nothing calculated, and a banner telling them to press Calculate. Copying a link does not save anything to your account, and it is unrelated to the Save action above.

Print vs. Export PDF

These are two separate report actions, gated differently:

Action	Where	Cost	Output
Print	Rail "Print", File menu "Print report"	Free, every plan	Opens your browser's print dialog (choose "Save as PDF" there) on the current result; carries a DRAFT watermark unless your plan removes it.
Export PDF	Rail "Export PDF", File menu, Report card	Pro	A branded PDF with your project header and logo, no watermark. Shows a PRO badge and prompts an upgrade on a plan without the entitlement.

Both actions read the currently displayed result — if it is marked STALE, Print and Export PDF are disabled until you press Recalculate, so the report can never show numbers that don't match the inputs on screen.

Keyboard shortcuts

Shortcut	Action
Ctrl/Cmd + S	Save
Enter	Calculate / Recalculate — except while typing in the fitting source-note field, or when focus is already on a button or link
