Use the left toolbar to place nodes, connect members, add support symbols, and apply node or member load arrows.
When adding members, click the start node first and then the end node so the member connectivity matches the intended joint layout.
Click any node, member, support, or load to edit it in the Properties panel on the right.
The bottom tabs are best for exact coordinates, member properties, load magnitudes, load factors, and ordered review of model data.
Drag nodes directly on the canvas to adjust span lengths, storey heights, or support positions.
Use the mouse wheel to zoom and drag empty canvas space to pan when checking labels, loads, and result diagrams.
Load tools let you define one joint force, nodal moment, UDL, or UVL and then apply that same definition to several nodes or members.
The case selector can be switched to All Loads to solve every load at `1x`, or to a named case when checking a specific scenario.
Create frame geometry, assign material and section properties, apply node loads and member loads, and solve selected load cases in one workspace.
Review support reactions, member end forces, axial force, shear force, bending moment, and displacement views after solving.
This app is provided as a practical engineering aid for modelling and review. Results should always be independently checked and verified by a competent person before being used for design, temporary works, construction, or safety-critical decisions.
Your message is delivered through the app backend and logged in the admin dashboard for follow-up.
If you are reporting a solve or modelling issue, include a clear reproduction path and the expected result.
