Tolerance Analysis for Early Design
Explore fit questions directly on your 3D assembly, while the design can still change.
Bring tolerance questions into the design loop
Will the parts still fit when their dimensions vary? Answer that question while the design can still change.
StackUp 3D brings tolerance analysis directly to your assembly, targeting 80% less time on early-design analysis. Validate the savings on your work.
Explore the assembly fit studies ↗Late fit problems cost more
Small dimensional changes across parts can become costly assembly problems.
- Parts that collide or fail to align
- Defects, scrap and rework
- Late changes that delay release
When analysis takes weeks, fit questions get deferred. Early checks give the team time to act.
See the fit question in 3D
Measure clearances, inspect potential clashes and compare tolerance choices in the assembly.
StackUp 3D uses deterministic mathematical calculations in a desktop application.
- Measurements the team can review in context
- Editable studies to revisit as the design changes
Shown: two selected mouse clearances with illustrative tolerance inputs.
What is waiting for an answer costing you?
Engineering hours, rework and delayed decisions all add up. Evaluate the business value of earlier tolerance analysis on one representative assembly.
80% less analysis time
Our early-design target. Measure the savings with your team.
Lower analysis costs
Spend fewer engineering hours preparing each decision.
Get ahead of rework
Find potential fit problems before they reach production.
Protect the launch schedule
Resolve fit questions before late changes delay the schedule.
What you can learn from StackUp 3D
Clearance
Measure the space between selected parts in their assembly context.
Interference
See where variation could cause a clash at the interface you are investigating.
Tolerance choices
Compare a changed input and decide which geometry or tolerance deserves attention.
Test the value on your assembly.
Bring a STEP assembly and a fit question. We’ll confirm the supported scope and measure the time saved. Detailed GD&T and final verification remain part of your engineering process.
