How is this different from the Measure tool?

The Measure tool is for straight lengths. Arc Tool follows a curve and gives you the true arc length along it, rather than the straight line between the two ends.

Can I measure a radius driveway or cul-de-sac?

Yes. Trace the curved edge and Arc Tool returns the real length along the curve at the correct plan scale.

Does it work on curved slab and pool edges?

Yes. Follow the rounded edge to keep perimeters honest for coping, tiling, edging, and formwork.

Do curved lengths sit with my other measurements?

Yes. Arc runs are saved on the plan alongside your lengths, areas, and counts, so the whole takeoff stays together.

Is the Arc Tool on the free plan?

Yes. The Arc Tool is on every plan, including Free. The paid plans lift the limits on projects, plans and markups, so you can take on bigger jobs.

How do I measure the radius of a curve off the plan?

Trace the curved edge and the Arc Tool shows the radius of the curve along with the true length along it, so you can read a radius wall, kerb or driveway straight off the plan instead of stepping it out with short straight segments.

What units does the arc length come out in?

You get linear metres at your plan scale, ready to drop into an edging, kerbing, or coping quote without any converting on the side.

Feature

Arc

Measure curved edges and radii accurately

Arc Tool traces the curved runs a straight line cannot, so curved walls, radius driveways, cul-de-sacs, and pool edges come off the plan as real numbers instead of rough guesses.

From problem to outcome

From a curve you cannot straight-line to a real length

Arc Tool is for the parts of a plan that refuse to be straight, curved walls, radius edges, rounded slabs, and sweeping driveways, where measuring point to point would undercook the length every time.

Step 1

Trace the curve

Follow the curved edge on the plan and let the arc bow onto the printed line.

Step 2

Read the arc length

Get the true length along the curve at the correct scale, not the straight-line chord.

Step 3

Keep it in your takeoff

Save the curved run with your other measurements, ready for materials and quoting.

Key capabilities

What you can do with Arc Tool

True arc length

Measure the real length along a curve instead of the straight line between its ends.

Best for Curved walls and edges

Radius runs

Follow radius driveways, paths, and cul-de-sacs so linear quantities come out right.

Best for Landscapers and concreters

Curved boundaries

Trace rounded slab and pool edges to keep perimeters honest on curved work.

Best for Slabs, pools, patios

Works at plan scale

Curved lengths come off a properly scaled plan, so the number matches the real job.

Best for Scaled PDF plans

Sits with your takeoff

Keep curved runs on the same plan as your lengths, areas, and counts.

The old way

Straight lines undersell curved work

Measuring a curve as a series of straight hops, or measuring the chord end to end, always comes up short, and short measurements on edging, kerbing, and cladding turn into money left on the table.

Chord measurements undercut the real curved length
String and short segments are slow and rough
Undercooked linear runs eat into the margin

Why it’s better with MetreMate

A proper way to measure the curves

Arc Tool follows the curve the way the material will, so curved edges stop being the thing you round off and hope for the best on.

Trace curved edges in one motion
Get the true arc length at scale
Price edging, kerbing, and cladding accurately
Handle radius driveways and cul-de-sacs
Keep curved runs with the rest of your takeoff

Testimonial / proof

“Mate, MetreMate is no joke. It actually helps me get more work done which means I get to make more money. This is such a nifty little tool. Recommend it to all tradies that work with plans.”

Concreters & Groundworkers

The problem

Need real lengths on curved driveways, kerbs, and rounded slab edges before pouring.

What you get

Accurate edge and formwork quantities on curved pours.

How you'd use it: Use Arc Tool to trace each curve and read the true arc length at scale.
