Description
Subtract productVolume from cavityVolume for voidVolume and mark fitsByVolume when productVolume is no greater.
A signed fit margin compares available space with an object and explicit allowances. Volume sufficiency, radial gaps, and diametral clearance are different conditions.
Subtract productVolume from cavityVolume for voidVolume and mark fitsByVolume when productVolume is no greater.
When to use this tool
Use Packaging Insert Cavity Volume Gap when you need one transparent product fit or travel-margin term.
How to use the tool and how it works
- Enter cavityVolume, productVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read voidVolume, fitsByVolume. Inspect fitsByVolume before interpreting the associated values.

}Limitations and assumptions
- Volume sufficiency does not imply geometric fit, insertion clearance, or protective packaging performance.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check complete three-dimensional geometry, tolerances, materials, and operating conditions before judging actual fit or safety.
