Count → Spacing
Input
L=6000, leftOffset=100, rightOffset=100, n=5
Output
Le=5800, pitch=1450, x=[100,1550,3000,4450,5900]

Important Notice
- This tool is for placement support only. It does not cover strength, pullout, anchorage length, or concrete design checks.
- For final decisions, follow applicable standards, site procedures, and supervisor instructions.
How to use
- Choose a mode: count → spacing or spacing → count.
- Enter total length L and left/right offsets, then confirm effective length Le.
- Select a layout rule (equal, centered, flush) and use quick actions when needed.
- Review the summary, schematic, and coordinate table, then export as TSV or CSV.
Examples
Spacing → Count (Centered + Ceil)
Input
L=6000, leftOffset=100, rightOffset=100, pitch=450, rounding=ceil
Output
nCandidate=14 does not fit, so it is auto-adjusted to n=13
Formulas
Le = L - leftOffset - rightOffsetn2p: pitchActual = Le / (n - 1)p2n: nCandidate = floor / ceil / round(Le / pitch) + 1equal: pitchActual = Le / (n - 1), remainder = 0centered: start = leftOffset + remainder / 2flush-right: start = leftOffset + remainder
FAQ
Why can input spacing and actual spacing be different?
In Equal spacing, the interval is recalculated to fill the effective length exactly.
What does the fit-priority badge mean?
It means the requested count did not fit under fixed-spacing rules and was automatically adjusted to a fitting value.
What does the centered-symmetry quick action do?
It sets both offsets to the larger value and switches the layout rule to Centered.
Can I use this output as a structural approval?
No. This is a placement-support tool only and does not perform structural verification.
