Industry Leading Tolerance Analysis Software

Build it right before you build it.

3DCS Variation Analyst leverages the CAD and PLM you’ve already invested in to identify and eliminate costly assembly issues — before tools are cut.

Find issues at the design stage,
not after tools are cut.

Every dimensional issue found in manufacturing costs 10× more to fix than one caught in design. 

3DCS moves that discovery upstream.

Our simulation software create Digital Twins in order to simulate assembly processes and tolerance stacks using 3D models.

From design tolerances to real measurement data — and back.

3DCS isn’t just a tolerance tool. It’s the starting point of a data thread that connects design intent to manufacturing reality.

1. Model

Build your 3DCS model inside your CAD. Define GD&T, locating schemes, and assembly sequences.

2. Simulate

Run thousands of digital builds. Identify variation contributors, risk areas, and sensitivity before a single part is made.

3. Close the loop​

Real measurement data from Metrolog feeds back into your model. Design decisions are validated against actual manufacturing capability.​

Four ways 3DCS protects your program.

Simulate variation before manufacturing

Run digital builds inside your CAD. Test gap & flush, interference, and assembly yield — with no physical prototype.

Validate GD&T with real data

Connect tolerance specs to actual measurement results. Replace assumptions with plant-floor evidence.

Quantify risk before production

Sensitivity analysis shows which tolerances drive the most variation. Prioritize where tightening actually matters.

Diagnose production issues from CAD

Import measurement data from the plant. Resolve root causes through your model — without stopping the line.

Engineers who can't afford to get it wrong.

“3DCS allowed us to move from 2D stack-ups to full 3D analyses — our team can now identify issues in a matter of days instead of weeks.”

Laurance Allmark — Senior Quality Engineer, McLaren Automotive
Medical

“We discovered sensitivities in areas we wouldn’t have expected — well outside our region of interest — that had significant influence on the beam.”
