EZtol 1 Year License Subscription for CATIA, NX, and SOLIDWORKS

Keep EZtol available for ongoing programs and continuous improvement work with a full 1-year subscription for CATIA, Siemens NX, and SOLIDWORKS. This is a single-user, node-locked EZtol license, which makes it a strong fit for an individual engineer responsible for recurring tolerance stack-ups, design reviews, supplier conversations, or late-stage change evaluations across multiple assemblies. 1-month subscriptions are also available.

EZtol helps you move beyond spreadsheet-only stack-ups by providing dedicated tools for 1D tolerance stack-up analysis so you can evaluate how part variation accumulates and affects assembly requirements. Manual calculations can become complex and unwieldy, and results are often difficult to review or repeat consistently. EZtol streamlines workflows with specialized calculations and visualizations, so your analysis is easier to validate, communicate, and reuse as designs evolve.

Because EZtol integrates with CATIA, NX, and SOLIDWORKS (with direct CAD model import), you can keep your stack-ups aligned with the design definition and update analyses as dimensions, requirements, and tolerances change - without rebuilding everything from scratch.

That helps teams surface crucial variation risks earlier, make better-informed tolerance decisions, and reduce downstream surprises when parts hit inspection and assembly.
