glyphs::Glyphs picks where a model's setup symbols go (resolving its sets once, thinning them on a grid, capping each definition and sampling large ones with a note) and draws them into a Scene at the nodes' current positions: cones for constrained translations (and rotations where nodes rotate), arrows for forces, double-headed arrows for moments, arrows normal to pressure faces, one arrow for gravity and body forces, a curved arrow for centrifugal loads, crosses with names for reference points, lines for couplings, hatched squares for rigid walls. Colours come from the caller by role, muted over results. Scene gains labels, drawn by the CPU rasterizer with a small bitmap font of its own.

FieldCraft
An open-source, clean-room CAE modeling application in pure Rust: geometry to analysis-ready finite element models, with robust tetrahedral and hexahedral meshing, solver decks for Abaqus, Nastran and LS-DYNA, and its own linear static and modal solver. Desktop, browser and AI agents drive the same commands.
Status: early. The workspace, quality gates, the FE model, the command engine and the geometry boundary (SolidCraft's kernel and tessellator) are in place; meshing is next. See ROADMAP.md.
An AI agent drives the app over MCP: it opens an I-beam, hex meshes it, defines the material, the clamp and a 1000 N tip load, solves, and shows the von Mises stress and the deformed shape (tip deflection 0.176 mm; beam theory with shear 0.177 mm). MP4 · regenerated by tools/demo-video.
Build
