Modular MathDesk
A structurally sound foundation for modern calculation. Connect your thoughts to outcomes fluidly with reactive blocks and intelligent unit support.
The best way to build calculation documents
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Large app-media placeholders mirror the reference layout while staying ready for Modular MathDesk videos and screenshots.
Built for real engineering work
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer vitae lectus sed arcu luctus dictum in a sem, with space reserved for a workflow video.
Designed for reusable calculation workflows
Suspendisse potenti. Curabitur commodo, justo at facilisis posuere, erat arcu varius massa, vitae luctus nibh justo id enim.
Adapts as inputs and assumptions change
Praesent non libero non mi volutpat aliquet. Donec pretium, magna vel finibus dictum, sem nisi tempor urna, vitae congue mi erat sed erat.
Made for polished calculation outputs
Aliquam erat volutpat. Mauris sed risus sed neque facilisis bibendum at at massa, leaving room for a report export preview.
Raises the bar across every project
Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia curae; this panel can later show review, traceability, or audit trails.
The same workflow through every stage
Lorem ipsum dolor sit amet, consectetur adipiscing elit. This section reserves multiple media slots for showing the app from setup through output.
Start in the desktop app
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Replace with a short loop showing a new calculation document.
Move through calculation modules
Integer vitae lectus sed arcu luctus dictum. Replace with a focused clip of reusable modules and live variables.
Finish with report output
Curabitur commodo erat arcu. Replace with a lightweight export or report-preview animation.
Engineering calculations that work the way you think
Not a spreadsheet. Not a word processor. A purpose-built tool for structural engineers who need accuracy, traceability, and speed.
Live Math Evaluation
Write expressions in natural math notation and see results instantly. Powered by a full symbolic math engine with dimensional analysis.
Unit-Aware Computation
Define calculations with physical units — mm, kN, MPa. The engine tracks units through every operation and catches dimensional errors.
Modular Documents
Create reusable calculation modules. Insert a beam check module into any project and it inherits the document's variables automatically.
Change One, Update All
Modify an input value and every dependent result recalculates in real time. No more manually chasing formulas through a spreadsheet.
Professional Output
Export clean, formatted PDF reports with headings, formulas, results, and commentary. Ready for client delivery or peer review.
Custom Variables & Units
Define project-level variables, presets, and even custom unit systems. Tailor the environment to your engineering discipline.
