Caliper – Measure and ReportFree Measure Tool Add-in for Autodesk Fusion (Fusion 360)

Measure once, read it clearly,
keep every value.

Fusion's Measure shows one value at a time, its numbers crowd each other on a busy model, and it forgets them when you pick again, so values end up on paper or in screenshots. Caliper writes each measurement on the model in labels you can read, keeps every value you save in one table across designs and restarts, and turns the table into a CSV file or a PDF report.

Autodesk Fusion with the Caliper dialog at the side: a motor bracket and a sensor block on a base plate, the 130.8 mm centre distance from a counterbored hole in the plate to a hole in the sensor block with its X part 115.0 in red and Y part 62.3 in green on the model, and the minimum, Min and Max edge-to-edge distances in the dialog — Caliper in the Fusion window: the value on the model, the details in the dialog.

What it does

Measuring that reads like a drawing

A motor bracket in Autodesk Fusion measured with Caliper: the bore centre 48.00 mm above the base with its Z part in blue, and the saved Bore Ø 32.00 mm and Base holes 90.00 mm in grey

Dimensions you can read

Labels face you, keep their size, stay in front of the part and move aside with a leader instead of covering each other.

Caliper in Fusion: the 33.3 mm centre distance from the pilot bore of a NEMA 23 motor bracket to one of its four motor holes, with its X part 23.6 in red and Z part 23.6 in blue

Holes: centre or edge

Between holes, arcs and circles: the centre distance and the nearest and farthest edge distances, as in SOLIDWORKS.

Caliper in Fusion: 157.80 mm corner to corner across a motor bracket with its X 110.00, Y 80.00 and Z 80.00 parts in red, green and blue

X, Y and Z parts

Every distance comes with its X, Y and Z parts, drawn in red, green and blue like Fusion’s own axes.

Caliper in Fusion: the volume 183352.70 mm³ of a motor bracket body with its size X 120.00, Y 80.00 and Z 80.00

Bodies: volume, mass, size

Pick a body for its volume, mass, size along X, Y and Z and its stock size, even when it sits at an angle; pick several and they add up.

The Caliper dialog in Fusion: units, Holes Centre/Min/Max, Pick Geometry or Bodies, and the saved measurements of this design with CSV and PDF export

A table that stays

Save a value with one click and name it. The table is there in every design and after Fusion restarts.

By hand or with Caliper

The checks you repeat, without the notes and screenshots

Task	With Fusion's Measure	With Caliper
Distance between two holes	Pick the two cylinders, read the minimum, work out the centre distance	Centre, nearest and farthest edge at once; choose which one is the main value
Offsets along X, Y and Z	Read the numbers in the dialog	Drawn on the model in red, green and blue, with their values
Several values on one view	One result at a time	Saved values shown on the model by name, next to the one you measure now
Keep the values	Write them down or take screenshots; gone when you pick again	One click: a named row in a table that stays in every design and after a restart
Hand the values to someone	Type a table by hand	Export CSV for Excel or an A4 PDF report

What it measures

Pick one, two or more

Click what you want to measure; the result appears at once. One pick gives its size, two picks the distance and angle between them, more picks add up.

For holes, arcs and circles, Holes picks the main value: centre to centre, or the nearest or farthest edges. The other two stay listed in the dialog.

You pick	Caliper shows
A vertex, sketch point or construction point	X, Y and Z
A straight edge or sketch line	Length, with its X, Y and Z parts
A circle or an arc	Diameter, radius, circumference or arc length, angle and the centre
A flat face	Area and perimeter
A hole, a shaft or a fillet	Diameter, radius, depth or length, and area
A cone, sphere or torus	Its angle or radii, and the area
A body	Volume, area, mass (from its material), size along X, Y and Z, and its stock size: the smallest box it fits in, even when it sits at an angle
A spot on a face or an edge (Points)	X, Y and Z of the exact spot you click; a second spot, even on the same face, gives the distance between them
Two items	Minimum distance, angle, X/Y/Z parts; for holes, arcs and circles the centre distance and the nearest and farthest edges; for parallel faces the distance between them
Three or more	Total length of edges, total area of faces, or total volume and mass of bodies with the overall size they take up

On the model

Dimensions that stay readable

✓The value you measure now in teal and bold; its X, Y and Z parts in red, green and blue.
✓Labels face you and keep their size while you orbit and zoom, and the part never hides them.
✓A label that would cover another one or a measured point moves aside, with a thin leader back to its place.
✓Saved values stay off the model until you click their eye; then they show in grey with their name.
✓Nothing is added to the design or its timeline.

A motor bracket in Fusion with five Caliper values at once: a base hole Ø 9.00 mm measured now in teal, and the saved Motor holes 66.67 mm, Bore to motor hole 14.58 mm, Bore Ø 32.00 mm and Hole pitch Y 38.00 mm in grey, none covering another — The base hole measured now, and four saved values shown by name.

One window

Measure, save and export in the same dialog

Open Inspect › Caliper, next to Fusion's Measure. The dialog shows the result, the options and your saved values.

✓Save to table adds the value as M1, M2… and keeps your picks; click a name to rename it.
✓One table for every design, kept when you switch documents and when Fusion restarts; it opens on This design, and All designs shows the rest.
✓Units mm, cm, m, in or ft with 0 to 6 decimals; the table follows when you change them.
✓Holes: Centre, Min or Max as the main value. Pick: geometry or whole bodies.

Saved values are a record of the model when you saved them; they do not follow later changes.

Questions

Caliper FAQ

Is Caliper really free?

Yes. There is no license, no trial and no time limit, and every feature is included.

Why do you ask for my email?

To know who uses Caliper and to tell you when a new version is out. We keep the email, the version and the time of the download; it is never shared or sold, and you can ask us to delete it.

What does Caliper send?

Only what our paid add-ins send: your Autodesk user ID and account email, when you open it, at most once a day, so we know who uses it. The answer tells Caliper about a newer version. Your designs, picks and measurements are never sent.

Does it run on macOS?

Yes. The same ZIP installs on Windows and on macOS.

Can I copy a value, or see it in inches too?

Yes. Click any number in the Caliper dialog to copy it, ready to paste into a spreadsheet or a Fusion dimension. Pick a second unit and every value shows in both, for example millimetres and inches.

Does Caliper change my design?

No. It adds nothing to the timeline; the dimensions are drawn over the model while the Caliper dialog is open and disappear when you close it.

How is it different from Fusion’s own Measure?

Fusion’s Measure shows one result at a time and forgets it when you pick again. Caliper adds the hole centre and edge distances, the X/Y/Z parts on the model, labels that do not overlap, a table that keeps your values, and CSV and PDF reports.

Where are my saved values kept?

In one file in your user folder, the same for every design: %APPDATA%\VanThanBK\CaliperMeasureAndReport\measurements.json on Windows, ~/Library/Application Support/VanThanBK/CaliperMeasureAndReport/ on macOS.
