STEP examples for this check

Geometry preview: Two cubes: 10 mm overlap

Machining · CC0-1.0

Two cubes: 10 mm overlap

Model example

Two separate 20 mm cubes; their origins are 10 mm apart along X and 10 mm along Y. The shared 10 × 10 × 20 mm region is unintended interference; inspect body boundaries in CAD.

Dimensions (approx.): 30 × 30 × 20 mm

Expected check result

PRU-071: expect one warning, overlap 2000 mm³ (the generic multiple-bodies note PRU-042 stays silent: same cause).

Two cubes: touching

Model example

Two separate 20 mm cubes; their origins are 20 mm apart along X and 10 mm along Y. Contact or a visible gap must not be called a volume collision.

Dimensions (approx.): 40 × 30 × 20 mm

Expected check result

PRU-071: no interference finding expected.

Model example

Two separate 20 mm cubes; their origins are 25 mm apart along X and 10 mm along Y. Contact or a visible gap must not be called a volume collision.

Dimensions (approx.): 45 × 30 × 20 mm
