Draw shapes by typing exact numbers instead of clicking by eye.

Coordinate input for polylines

When drawing a polyline, you can now type the next point's coordinates instead of clicking. Two modes:

• X, Y — give the absolute position of the next point
• Length and angle — give the distance and direction from the previous point

This makes it easy to build exact shapes. For an equilateral triangle, for example, just use the same length for each side and 60° angles.

Pro tip: after placing the first point, press X, Y, L, or A to jump straight to that input — then hit Enter to apply the value.

Line or polyline

You can now choose between a plain line (two points) and a polyline (chain of connected segments) when drawing members.

A bunch of things that should make building trusses a lot less frustrating.

Hover feedback and tooltips

• A hover state indicator shows which element your cursor is over — no more guessing what will get selected when you click
• Tooltips appear when you hover over elements, showing their key properties and results

Better snapping

Three new snap targets when placing nodes:

• Point on line — snap to any point along an existing member, not just its endpoints
• Line center — snap straight to the midpoint of a member
• Perpendicular — snap at a right angle to a member

If you've ever spent 30 seconds trying to hit a midpoint by eye, this one's for you.

Enhanced load inputs

The load input controls have been improved. They're easier to add/update or delete loads on nodes.

Axis rulers

There's now a ruler along both the X and Y axes. Handy for checking coordinates at a glance.

You can now choose between Metric and Imperial units in the calculator setup. All inputs and results display in the selected unit system.

I work in metric day-to-day, so imperial support got less real-world testing — if anything looks off, I'd really appreciate a heads-up. Use the feedback button above and describe what you expected to see.

This is a significant update — most of the work happened under the hood, but it sets the foundation for everything coming next.

Rebuilt from the ground up

The entire app state has been rewritten. The old system was getting in the way of adding new features, so it was replaced with something leaner and more predictable. From the outside it should feel the same — or better — but internally it's a much cleaner foundation.

Calculator redesign

The calculator interface has been reorganised to support more powerful features without becoming cluttered. Controls are easier to find, and the layout scales better as more tools get added.
