DrawSession: - Add DrawSolid() — renders Solid faces as PositionNormal triangles with ambient/diffuse lighting, tessellates edges as lines. Supports transparency (0.0–1.0) with correct opaque/transparent pass handling. - Add DrawMesh() — renders Mesh as flat-shaded triangles with per-triangle normals computed from cross product. - Split GPU buffers into _lineBuffers (Position+LineList) and _triBuffers (PositionNormal+TriangleList) for independent pipeline paths. - UseInTransparentPass() returns true when any solid has transparency > 0. - RenderScene() handles both passes: opaque (lines + solid faces) and transparent (transparent faces only). - CanExecute() and ComputeOutline() account for all three primitive lists. - Clear() clears lines, solids and meshes. - Fix: Remove auto-registration from constructor — registration is now explicit via RegisterDrawSession() or Register(). - Fix: VertexBuffer/IndexBuffer.Map(0) → Map(actualSize) — Map() takes buffer size in floats/shorts, not an offset. Passing 0 wrote no data. UIControlledApplicationExtensions: - Add RegisterDrawSession() extension on UIControlledApplication. Encapsulates correct DirectContext3D registration order per Revit API docs: AddServer → GetActiveServerIds → Contains check → SetActiveServers. Replaces ~10 lines of boilerplate with a single call in OnStartup. Docs: - README: Add DrawSession and DrawExtensions usage sections with full examples. - CLAUDE.md: Add DrawSession section covering registration pattern, UIApplication lifecycle, fixed bugs, CanExecute conditions, threading model.

- Fix black faces: pre-compute all triangle data (Triangulate, ComputeNormal) in DrawSolid/DrawMesh on the main thread instead of calling Revit geometry API from the render thread (where it silently fails, producing zero normals) - Replace _solids/_meshes raw storage with _triData (pre-computed tuples) - Add DrawBox(XYZ min, XYZ max), DrawBox(BoundingBoxXYZ), DrawBox(Outline): filled axis-aligned box with 12 wireframe edges, pure math triangulation - Add DrawSphere(XYZ center, double radius): UV sphere (16x32 rings) with 3 great-circle wireframe edges, pure math triangulation - Rename private DrawBox helper to DrawWireBox to avoid name conflict Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…DotNet - Replace stroke-font approach with GraphicsPath.AddString() → Flatten() → LibTessDotNet tessellation so any system font renders as filled triangles (handles holes in O, A, B, D, etc.) - Add _textCache static dict: normalised (height=1.0, Y-up) triangles cached per (text, fontFamily) - Add BuildTextTriangles / ExtractContours / GetFontFamily private helpers - Remove AppendThickSegment and _strokeFont dictionary (old stroke-font code) - Add DrawPoint(XYZ, string label, ...) overload: cross + DrawText label - Add DrawBox(min,max) / DrawBox(BoundingBoxXYZ) / DrawBox(Outline) — pure-math box triangulation - Add DrawSphere(center, radius) — UV-sphere 16×32 tessellation, no Revit geometry API calls - Add DrawSolid / DrawMesh with main-thread pre-computed triangles (fixes black faces on render thread) - Add LibTessDotNet v1.1.0 + System.Drawing.Common v8.0.0 (net8) / System.Drawing ref (net4x) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…uGet pack - Add DrawSolid, DrawMesh, DrawBox, DrawSphere, DrawText sections with code examples - Add full method reference table for DrawSession - Add color reference table - Drop Revit 2027 from supported versions list - Fix NU5019: icon.png path in csproj was pointing to repo root instead of project folder Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
