Tekla Tedds is useful for teams to run quick calculation and design analysis. Calcs.com provides a platform for engineering teams to actually do all the things needed to move projects forward efficiently and effectively.
Calcs.com delivers the same caliber of code-backed calculations as Tekla Tedds, with an extensive library aligned to the latest standards like IBC, CBC, and FBC.
Because our calculators are cloud-based and updated from real user feedback, the library keeps expanding quickly across wood, steel, concrete, lateral loads, and connections, so you see new coverage appear in months, not release cycles.
In Tekla Tedds, each calculation exists as a separate document, so engineers manually pass reactions from one sheet to the next.
In Calcs.com, project-based load linking keeps your calcs connected, tracking the load path from roof to foundations and from lateral loads through diaphragms into shear walls. When something changes, connected members update automatically, eliminating copy‑paste workflows and making it much harder for missed updates to sneak into your design.
Turn on Reference Mode to see the exact codes, standards, and formulas behind every result, right inside the calculator.
Unlike Tekla Tedds, where references only appear in the final document after you run the analysis, Calcs.com surfaces them inline as you work. Engineers learn as they go, build confidence in the numbers, and stay up to date on design requirements without ever leaving the workflow.
Because Calcs.com calculators are linked to extensive member databases, engineers can test alternate sections and grades in a few clicks, with utilization and governing checks recalculated instantly. That makes value engineering practical: you can explore more alternatives, tighten up designs, and still hit deadlines.
Because Calcs.com is cloud-based, your entire team works from the same workspace instead of scattered desktop files. Projects, calculators, and reports live in one place, so engineers always see the latest version, can review each other’s work, and keep calculations aligned across the whole structure.
Teams can turn proven setups into reusable project templates, so regional defaults, local code settings, and client-specific preferences are baked in every time a new project is duplicated.
Rapidly growing library of prebuilt, code-backed calculators focused on modern workflows,
Large library of code-based templates
Project-based workspace where grouped calculations share the same defaults and project location automatically draw environmental loads like wind, seismic and snow.
Supports project files, but loads and criteria are often managed per sheet, with environmental data and settings entered manually.
Reference Mode surfaces code clauses and formulas inline within each calculation, so engineers can see the “why” behind results as they design, not only after they finish.
Shows code references and formulas in the generated document after all inputs are entered, so verification happens at the end of the workflow.
One-click PDF export with flexible output, from a compact one-page summary to a fully detailed report, so engineers can match the level of documentation to reviewers and project needs.
Calculations are displayed in a document-style format inside the desktop interface, with limited flexibility over report length and layout.
Calcs Builder (currently in beta) sits earlier in the workflow and is built for teams to create, standardize, and maintain a single source of truth for their structural calculations with drag and drop widget.
Tedds for Word lets engineers embed custom calculations into Word-based reports when they need bespoke calculation packages. displayed in a document-style format inside the desktop interface, with limited flexibility over report length and layout.
Load Linking automatically pushes reactions from beams to columns to foundations, so changes propagate through the load path without copy-paste or missed updates.
Requires engineers to manually pass reactions between members and update each affected sheet when loads, spans, or sections change.
Calculators are connected to tens of thousands of manufacturer sections with automatic pass / fail checks, so engineers can browse options and see utilization update in real time as they design.
Engineers manually select member types and input section properties before analysis can run, which slows down iteration across different shapes or grades.
Cloud-based workspace where engineers log into the same environment to access shared projects and calculators. Projects, templates, and updates are stored centrally, so team members always see the current design, can collaborate in real time, and can standardize workflows across locations without managing local installs.
Installed, desktop-based software where project files live on individual machines or shared drives. Teams often rely on local copies, email, or folders to coordinate, which makes it harder to keep everyone working from the latest version of the calculations.
Create a free Calcs.com account in minutes. No desktop installer, no license activation or credit card required.
Set up a project for a real job (for example, “Smith Residence – Deck Design”). Enter the project location so Calcs.com can automatically pull the right environmental loads.
Add the core calculators you use most in Tedds (for example, timber beam, steel column, footing). The UI is designed so you can recreate these checks quickly and keep them linked inside one project.
Toggle the Reference Mode to see codes and formulas inline while you design. Export a one-page summary or detailed PDF when you are ready to share calcs with reviewers or clients.
Once your first project is running smoothly, standardize it as a pattern for similar jobs. Invite more engineers into the same workspace so your team moves from individual Tedds files to a shared, cloud-based workflow.
