Use the left toolbar to add nodes, members, supports, node loads, and member loads.
When adding members, click the start node first and then the end node.
Click any node, member, support, or load to edit it in the Properties panel on the right.
The tabs on the bottom are useful when you want to edit lists, sort items, or work more numerically.
Drag nodes directly on the canvas to reshape the model.
Use the mouse wheel to zoom and drag empty canvas space to pan around the model.
Quick load tools let you define the load once, then keep clicking nodes or members to apply the same load repeatedly.
The case selector can be switched to All Loads to review everything together on the canvas.
Create frame geometry, assign properties, apply node and member loads, and solve the model in one place.
Review reactions, 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.
