EngineersCalc / Engineering Tools
From design requirements to practical dimensions and component choices. Combine engineering rules, reference data and geometry checks in one focused tool.
Purpose-built for machine design
Design selectors turn repeated catalog lookups, dimensional stack-ups and sizing procedures into usable engineering outputs. They help establish a starting configuration; the engineer remains responsible for application checks and final design decisions.

Two ways to solve a design problem
Combine standardized dimensions, assembly stack-ups and installation constraints into geometry you can apply when modelling a part.
Example: bolt recess, washer stack or retaining-ring groove.
Calculate operating requirements and compare them with documented component limits, performance data and installation conditions.
Example: industrial shock absorber or gas spring sizing.
From a requirement to a usable result
Enter dimensions, movement conditions or assembly requirements relevant to the design task.
The selector evaluates the supported rules, standard dimensions and limitations of its data set.
Use the resulting dimensions, selection rationale and cautions as design inputs for engineering review.
Results depend on the selected standards, catalog records and assumptions supported by each tool. A suggested dimension is not automatically a manufacturing tolerance, strength verification or confirmation of fit in your assembly. Always check the applicability, source data and design conditions before release.

It is a focused tool that helps turn engineering requirements into a proposed geometry, component specification or configuration by applying defined sizing rules and reference data.
A calculator commonly produces a numerical result or verification. A selector uses calculations plus component dimensions, constraints or selection rules to help choose a usable design configuration.
Dimensions may be useful as modelling inputs, but you must check the individual selector's scope, applicable standards, clearances, tolerances and manufacturing requirements. A schematic is not a manufacturing drawing.
