This release is a pre-release and may not be stable for production use.
PyniteGUI
A desktop application for modeling and analyzing 2D/3D frames and axial-only trusses, built with Qt and the PyNite solver.
Documentation · Releases · Examples · Report an issue
Published release candidate: 1.0.0rc2. Development checkpoint: 1.0.0rc3 (unpublished). See validation and platform status for the tested configurations and remaining checks before stable 1.0.
What You Can Do
- Build a model: draw frames and trusses, edit tables, assign materials and sections, and define supports, springs, planar member releases and load combinations.
- Analyze: linear elastic analysis and restricted frame-only P-Delta, with progress, cancellation, self-weight and unit-aware inputs.
- Inspect results: 2D/3D force diagrams, signed colour maps, exact member station probes, combination comparisons, envelopes and explicit storey drift.
- Work comfortably: Model/Results workspaces, SI/Imperial units, light/dark themes, undo/redo, autosave recovery, CSV and printable reports.
- Learn and automate: categorized examples with previews, adapted official PyNite examples, and an optional MCP server for controlling the open editor.
Surface meshing, rectangular plate analysis and coupled rectangular Quad slabs are experimental. P-Delta keeps materials elastic and has model restrictions; plastic, modal and reinforced-concrete nonlinear workflows are not implemented. Read the engineering scope before relying on results.
Install and Run
Requires uv and Python 3.12+. uv can manage Python and the application's isolated environment.
From PyPI: install the release candidate in an isolated tool environment:
uv tool install --python 3.12 "pynitegui==1.0.0rc2"
pynitegui
If the command is not found, run uv tool update-shell and reopen your terminal.
With pip, use python -m pip install "pynitegui==1.0.0rc2" inside a Python
3.12+ virtual environment, then run pynitegui. The explicit version selects the
prerelease. Release wheels are also available on GitHub; standalone desktop
installers are not provided.
From this repository:
uv python install 3.12
uv sync --managed-python
uv run pynitegui
Open File > Examples to browse ready-to-analyze models, or choose
File > New 3D Frame. If 3D graphics fail to start, launch with
pynitegui --software-rendering (or uv run pynitegui --software-rendering).
Optional MCP: use uv run --extra mcp pynitegui from the checkout, or install
"pynitegui[mcp]==1.0.0rc2" with uv tool install --python 3.12.
Configure permissions, exclusive MCP mode and authentication in
Tools > Automation Server. See the MCP guide.
