Display Controls
Toggle between Wireframe, Outlined, and Rendered views.
Toggle visibility of supports, member fixities, labels, and loads.
Tip: Right-click Labels or Loads for detailed options (e.g., Node IDs, Load Values).
Toggle visibility of global axes, origin point, nodes, and members.
Local Plane Toggles — Control which member result planes are visible. Only active when analysis results are displayed.
- XY — Results in local XY plane (Major Axis).
- XZ — Results in local XZ plane (Minor Axis).
Result Views

Right Sidebar (Properties)
The properties panel is context-sensitive, showing details for the currently selected nodes or members.
Member Properties
- Member Type: Normal, Tension/Compression Only.
- Section: Assign cross-sections from the library.
- Material: Assign materials from the library.
- Fixity: Define fixity to each node for all DOF (Fixed/Pinned).
- Sideways: Turn the section 90 deg.
Node Properties
- Position: X, Y, Z coordinates.
- Restraint: Define supports (Fixed, Pinned, Roller, etc.).
Command Line
A non-interactive rolling history appearing at the bottom of the canvas. It displays the last 5 active command prompts, drawing instructions, and action logs (e.g., modification results).
