Cad Func is a focused companion for designers and engineers that turns complex CAD math into fast, accurate, and reusable results. Build named formulas, drive dimensions with variables, and solve geometry, tolerance, and unit conversions without leaving your workflow.

Key features:

Function-driven calculator: Write expressions with variables, units, and constants to standardize your calculations.
Geometry helpers: Quickly compute areas, perimeters, volumes, radii, angles, fillets, and chamfers.
Parametric sets: Create input forms that recalculate all dependent values at once.
Tolerance and fits: Run basic stack-ups and check clearance or interference with concise outputs.
Unit-smart: Convert between metric and imperial units, linear and angular measures, and common engineering quantities.
Libraries: Save and share formula sets and presets to keep teams aligned.
Results you can use: Apply rounding rules, format outputs, and copy results directly into your CAD or notes.
Streamlined UI: Keyboard-friendly controls, history, and undo for quick iteration.
Extensible: Define custom constants and functions to match your standards.

Common use cases:

Pre-sketch dimensioning and constraint planning
Selecting drill sizes, fits, and tolerances
Estimating material usage, mass, and center-of-gravity inputs
Generating consistent values for drawings and BOM notes
Teaching and documenting design intent

Why Cad Func:

Reduce rework by making math explicit and repeatable
Eliminate context switching and manual conversion errors
Standardize calculations across projects and teams

Getting started is simple: define your variables, write your formulas, and save them as a preset you can reuse on similar parts. With Cad Func, you spend less time wrestling with numbers and more time designing.

The most popular version of Cad Func among our users is 5.0. The name of the program executable file is CADFUNC5.EXE.
