Most firms rebuild their standard templates in Calcs.com over the first few weeks. Because Calcs.com connects calculations through live load paths, the rebuilt versions tend to be more useful than the originals. ## Start with your standard templates Do not try to move everything at once. List the calculations your office actually repeats. That is usually a short set: a few beam types, a column, a footing, and a connection or two. Rebuild those first in Calcs.com. Most engineers report that rebuilding a core set takes a day or two. Firms with a larger Tedds library typically spread the work across the first few weeks, rebuilding templates as live jobs call for them. ## Rebuild as linked calculations, not separate sheets The rebuild is a chance to improve the structure rather than copy it. Calcs.com connects calculations through live load paths, so a beam reaction can feed the column that supports it. See [Linking Loads and Reactions Between Calculators](/docs/running-calculations/linking-loads/linking-loads-reactions-between-calculators-load-path-tracking). Engineers who rebuild this way end up with a connected project rather than a folder of independent sheets. Change a load at the top and the members below it update. ## Check coverage before you commit Run two or three recent jobs through Calcs.com and compare the results against your Tekla Tedds output. It confirms that your standard member types, materials, and regional standards are covered. It also builds confidence in the numbers before you rely on them. A free trial is the usual way to do this. See [Start Your 14-Day Free Trial](/docs/plans/free-trial/start-your-free-trial). ## Keep Tekla Tedds running during the changeover There is no need to switch off Tekla Tedds on day one. Most teams run both for a period, then retire the old calculations once the rebuilt versions have been used on real jobs. See [Migrating from Spreadsheets](/docs/get-started/migrating/migrating-from-spreadsheets) for how to run both side by side. If a calculation you rely on does not appear to have an equivalent, email [support@calcs.com](mailto:support@calcs.com) before assuming it is missing. ## Frequently asked questions Tedds templates use a proprietary format that cannot be imported directly. Most firms rebuild their standard templates in Calcs.com over the first few weeks. Because Calcs.com connects calculations through live load paths, the rebuilt versions tend to be more useful than the originals. Calcs.com covers major Australian, New Zealand, US, and Eurocode standards. See [Standards Available](/docs/running-calculations/standards-and-codes/standards-available) for the full list. Tedds has a broader legacy library for UK and European codes in particular. If your practice relies on specific niche codes, contact us before switching. Calcs.com exports calculation reports as PDFs. The reports are structured and formatted for submittal, so most engineers find they no longer need the Word editing step that Tedds output typically requires. See [Views and Export](/docs/running-calculations/exporting-reports/views-and-export). Yes. ClearCalcs became Calcs.com in 2025. It is the same product, built by the same team, under a new name. See [ClearCalcs Is Now Calcs.com](/docs/get-started/about/clearcalcs-is-now-calcs). ## Related * [Migrating to Calcs.com](/docs/get-started/migrating) * [Migrating from Spreadsheets](/docs/get-started/migrating/migrating-from-spreadsheets) * [Start Your 14-Day Free Trial](/docs/plans/free-trial/start-your-free-trial)
