To ensure fair use of the platform for all subscribers.
Each new PDF export from the calculator uses one credit, including exporting the same assembly again - for example after changing the company logo, project details, report information, or the assembly itself.
Downloading a report you already exported again from the Reports page does not use a credit. Reports exported on the Free plan stay watermarked when downloaded again.
Daily and monthly limits are enforced independently. If you reach either limit, exports are unavailable until the daily window resets at midnight UTC or the monthly window resets on the first of the next calendar month.
Professional and Business subscribers can buy an add-on pack of 3 extra PDF exports for $10.90, when the pack is offered on the Plans page. Add-on credits must be used before the end of the calendar month they were purchased in - unused credits do not roll over. You can buy up to 2 add-on packs (6 extra exports) per calendar month. Add-on credits still count toward your daily export limit.
If you have questions about these limits, or a legitimate use case that needs higher limits, contact support.
