Time-saving tips and tricks to optimize structural design at Calcs.com (US)

Setting project-level defaults to reduce repetitive entry

Eva Wu opened the session by walking through project configuration. At the project level, engineers set the building standards jurisdiction (US, Canadian, or Australian), the unit system (metric or imperial), and default values for loads, geometries, and design codes. These settings apply to every calculator opened within the project, so a standard residential project setup might specify IBC with ASCE 7 load references and imperial units once, with those choices pre-filled in every subsequent calculation.

Eva demonstrated how project defaults work in practice by changing a default load value and showing every linked calculator update automatically. She noted this is particularly useful when a design assumption changes after calculations are already underway, because the engineer updates one value rather than editing each calculator individually.

Changing materials without rebuilding calculations

A feature Eva highlighted was the ability to switch structural materials mid-design. The change material function converts a calculator from one material to another, for example from a timber beam to a steel wide flange, while preserving the existing span, applied loads, and geometry inputs. The engineer does not need to re-enter the loading or span data, only review and adjust any material-specific inputs that differ between the two calculators.

Eva showed the workflow for a beam being evaluated in both timber and steel to compare sizing and utilization side by side. She created a copy of the original calculator, applied the material change to the copy, and renamed both to distinguish them. The comparison allowed her to evaluate member depth and utilization for each option without maintaining two separate input sets.

Load linking and inline math

Load linking connects the reaction output of one calculator directly to the load input of the next element down the load path. Eva demonstrated a load path chain where a beam reaction fed a post, which fed a spread footing. Each time a value changed upstream, all linked calculations updated without manual intervention. She described this as eliminating the transcription errors that occur when reactions are manually re-entered at each step.

Calcs.com input fields also accept Excel-style expressions. Eva showed entering a distributed load expressed in kilonewtons and converting it to pounds per foot inline, and applying a trigonometric function to resolve a sloped load component. She noted that trigonometric functions use radians by default, and that standard constants including pi are available in the expression syntax.

Exporting to CSV and Excel for contract documents

The export function produces a spreadsheet containing member data, sizes, and end reaction values. Eva noted that the reaction data in the export is directly usable for drawing callouts and material schedules, avoiding the need to transcribe values from individual calculation sheets into a separate table.

For contract document preparation, the CSV export can be used for quantity takeoffs or imported into a drawing management workflow. Eva also mentioned a connection to VINLINK for transferring member data to Revit. Each sheet can be exported individually or all sheets can be exported together depending on the document packaging requirement.

Upcoming features: code references and simple templates

Connor Conzelman mentioned two features in development at the time of the session. The first was direct code reference integration, where buttons within each calculator would link to the specific code clause being applied, allowing engineers to navigate directly to the relevant section of IBC, ACI, or AISC without opening a separate document. A Standards Australia agreement was already in place at the time, with IBC and AISC in progress.

The second feature was the simple wood beam template, which presents essential inputs on a single page for routine dry-service designs, reducing scroll time for repetitive residential beam sizing while keeping the full-featured calculator accessible when the application requires it.
