Several solid bodies

Scope and limits

Flag STEP files with more than one disconnected solid body. Silent when the bodies overlap (PRU-071) or when every extra body is a loose plug inside a cutout of the sheet while the cutting rules run (PRU-087).

Standards and references

No standards reference is assigned to this check. The scope described above applies.

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).
