Stage Wing Prop Clearance Gap Tool

Description

For nonnegative openingWidth, propWidth, and sideAllowance return margin=openingWidth-propWidth-2*sideAllowance and fits when margin>=0.

A production plan combines stage geometry, cue times, movement distances, material dimensions, and explicit scheduling or accounting rules. Signed margins reveal surplus or deficit under the chosen model. Physical clearances, execution variability, and governing requirements can require checks beyond one arithmetic term.

For nonnegative openingWidth, propWidth, and sideAllowance return margin=openingWidth-propWidth-2*sideAllowance and fits when margin>=0.

When to use this tool

Use Stage Wing Prop Clearance Gap when you need this specific stage, cue, material, timing, count, or fee term under supplied production assumptions.

How to use the tool and how it works

Enter openingWidth, propWidth, sideAllowance. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read margin, fits. Inspect fits before interpreting the associated values.

For nonnegative openingWidth, propWidth, and sideAllowance return margin=openingWidth-propWidth-2*sideAllowance and fits when margin>=0.^[1]

sideAllowance	Side Allowance	Required. Finite number; minimum 0.

Output field	Interpretation	Returned shape
margin	Signed surplus or deficit under the stated supplied rule.	Required. Finite number.
fits	Fits	Required. Boolean.

Limitations and assumptions

Lengths need one unit. Fits checks one static width budget without depth, turning radius, handles, moving personnel, structural clearance, or safe stage access.
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. Signed zero is exported as zero.

Alternative or Complementary methods

Use a complete production schedule or equipment/layout assessment when one margin is insufficient. Check units, timing conventions, tolerances, and physical constraints before combining terms.
