Calculator
Updated v2.3.8At a glance
- A themed desk calculator available in every workspace — and from inside any numeric input
- Functions, powers, and constants beyond what dimension fields accept
- Paste a number or a whole formula, and copy the result back out with one click
- Closes the loop with Quick Measure — measure, copy, paste, calculate
- Launched from a value field, Use drops the result straight back into the input
- Degrees/radians aware for trig
JetCad3 keeps a desk calculator built in so quick shop math never means reaching for your phone.
Every workspace — Drafting, Design, Plasma, Laser, Router, and GcodePilot — has a Calc button
right on its toolbar that opens it as a movable window you can leave open while you work (in
GcodePilot it also keeps its c shortcut). In Drafting and Design it lives in the labeled
Utility group next to Search, and it stays on the toolbar while you're
editing a sketch. Value prompts that show a calculator icon beside the
input — like GcodePilot's set/increment axis prompts — open it in a second mode with Cancel and
Use buttons: work out the number, hit Use, and the result lands back in the field for you to
confirm.
Beyond the dimension fields
Dimension inputs across JetCad3 already evaluate basic math — + − × ÷, parentheses, and unit
suffixes like in and mm. The calculator picks up where they stop: powers (^), square and cube
roots, factorial (!), percent, ln/log/exp/abs, the constants π and e, and the full set of
trig functions (sin cos tan asin acos atan) with a Deg/Rad toggle so 45 means 45 degrees when
you want it to. The mode you pick is remembered between sessions.
Views and keyboard entry
Two layouts toggle and persist: Compact, a plain four-column pad, and Scientific, which
adds the function block. Every button is also a live hotkey while the calculator has focus — digits
and operators type straight in, Enter is equals, Backspace deletes, c clears, and Escape
closes (or cancels, when launched from an input). Buttons flash as you type so you can see the
keystrokes register. The whole thing is drawn with the app's theme tokens, so it matches whatever
look you've picked in Themes.
Copy and paste
The calculator works with your clipboard both ways. Paste (Cmd/Ctrl+V) drops in a value you've
copied from anywhere — a measurement from Quick Measure, a number from
another app — or a whole formula like 1+(2/3)*4, which evaluates the moment it lands. Pasted math
is tidied into the calculator's own look, and a stray in/mm label is dropped since the
calculator works in plain numbers. A small copy icon sits beside the running answer: click it (or
press Cmd/Ctrl+C) to copy the result as a plain number that pastes cleanly into any measurement
box. That closes a common loop — measure a part, copy the value, paste it in, do the math, and copy
the answer straight back into your design.
