Clearance & Fit

Will these two parts fit?

Choose two local models, place each one deliberately, and check the gap or interference between them: minimum clearance with its closest-point pair, ranked tight regions, and exact triangle-pair interference evidence.

Step 01

Choose both parts

Select two supported files. Each part starts at the identity placement -- not moved, not aligned to the other -- until you set an explicit translation or rotation for it below.

First partChoose a modelSTL, OBJ, glTF, GLB, or 3MF, up to 32 MiB

Expert settings

Change these only when the source uses a different unit or up-axis. The selected values are recorded with the check.

Placement (optional)

This part starts at the identity placement -- not moved -- unless you set a translation or rotation below. VoxelSpy never auto-positions or auto-aligns either part: this is the only way a part’s placement changes, and the resulting transform is shown below for audit.

Desired clearance

Minimum acceptable gap

The minimum surface-to-surface distance you want between the two parts, in millimetres. Zero means the parts must not touch.

Desired clearance (mm)

Choose both source files

Local boundary: both source files and their geometry stay inside this browser's dedicated clearance worker; only the structured report leaves the worker, and nothing is uploaded.
