Mining Annotation Scale Checker

Review mine plan annotation: plotted height = model height × 1000 ÷ scale, per-style results against your own minimum, plus a final-size readability record.

Project and review scope

An annotation review for one mine plan: a plotted text-height table from your model heights and plot scale, compared with YOUR minimum, beside a manual review of the sheet at final size. It does not read the drawing and sets no universal text height.

Plotted text-size table

Paper height (mm) = model height (m) × 1000 ÷ N. Results are compared with YOUR minimum only; then review the printed sheet for clipped labels, crowding and symbols at final size.

mm
Height in model units; add “paper” for paper-space or annotative text already sized in mm.
Model height to plotted height
Not to scale
Model height to plotted heightText drawn in model space at a model height is divided by the scale denominator to give its plotted height on paper. Paper-space text is not scaled.Model spaceAah (model units)÷ NPaper (plotted)Aah ÷ NPaper-space text: not divided by the scale
Paper height = model height ÷ scale denominator (in consistent units). Paper-space text uses a separate convention and is not scaled.
  • Note: Enter the plot scale 1:N to compute plotted heights.
  • Check: Model units unknown — plotted heights of model-space text are NOT computed. Declare the units.
  • Note: No minimum entered: plotted heights are listed, not judged (there is no universal minimum).

Outstanding critical findings

  • Model units and annotative text mode declared — Not started

Review rows

Plot scale and sheet

0/3 verified

  • Plot scale stated and matches the scale bar

  • Sheet size and orientation correct

  • Scale bar and north point present

Text styles and heights

0/5 verified

  • Text heights legible at plot scale (e.g. ≥1.8-2.5 mm)

    Compare with the minimum your client or site standard sets — no height is universally legible.

  • Consistent text styles / fonts across the sheet

  • Model units and annotative text mode declared

    Critical

  • Each style has model and plotted height

  • User minimum and its source recorded

    Critical

Readability at final size

0/5 verified

  • Labels not overlapping linework or each other

  • Levels / RLs and dimensions readable

  • Final-size clipping and crowding reviewed

  • Contour labels not crowded at final size

  • Symbols and point markers legible at final size

Linework, hatching and symbols

0/3 verified

  • Line weights differentiate features at scale

  • Layer / lineweight standard followed

  • Hatching and symbols print clearly

Title block and issue

0/2 verified

  • Title block complete (datum, scale, issue, author)

  • Revision and issue status correct

How to use this calculator

  1. Record the drawing, plot ratio and paper size, drafting standard and your lineweight/hatch review notes.
  2. In the text-size table enter the scale denominator N, the model units, your minimum plotted height and its source, then list each text style as “name, height” (add “paper” for paper-space or annotative text).
  3. Review the plotted sheet at final size for clipping, crowding, symbols and linework, then export or print the record with the height table.

How it works

Plotted height (mm) = model height (m) × 1000 ÷ N; for model units in mm it is h ÷ N and in feet h × 304.8 ÷ N. Unknown model units are labelled and not computed.

Paper-space or annotative text already has a paper height, so it is listed separately and not divided by the scale. Each style shows its value, your minimum and the result; a style below your minimum blocks “Ready for reviewer”.

There is no universal acceptance height — results compare only with the minimum you enter and cite. This is annotation review; the Plan Annotation Scale Calculator solves a text size.

Worked example

1:1000 contour labels. Model text 2 m high at 1:1000 plots at 2 × 1000 ÷ 1000 = 2 mm. Against a project minimum of 2.5 mm the style reads “Below user threshold”; against a 2 mm minimum it meets it exactly; with no minimum entered it is listed, not judged.

Frequently asked questions

What has actually been checked?

Only what a person marked Verified, with the evidence they recorded. The text-size table uses the heights you entered; the final-size rows record your own look at the printed sheet.

Can I use my own project requirements?

Yes. Enter your client or site minimum and where it comes from — no height is built in. Add your own rows (they get stable IDs), and mark rows that do not apply as Not applicable with a reason.

Does a complete checklist prove the work complies?

No. “Ready for reviewer” is your declaration that every applicable row is verified. Drafting standards and the client decide acceptance.

How is this different from the Plan Annotation Scale Calculator?

That calculator solves for a text size. This checker reviews every style on a sheet against your minimum and records the final-size readability review.

Is this official course material?

No. It is free study support mapped to surveying course levels — not official North Metropolitan TAFE content or advice. Always follow your lecturer and the official assessment brief, and check your own working.
