## Development Phases — 第四輪（效能，全部完成）

### Phase 12 — 大組件量測流暢度（工作量：M）
|
||||
|
||||
**問題：** 大檔（39MB / 64k 面）瀏覽轉動順，但一進量測模式轉動就嚴重卡頓。
|
||||
**根因：** 量測模式渲染逐面（每個 B-rep 面 1 個 `GeometryModel3D`），64k 面 = 64k draw call，
|
||||
WPF retained-mode 每幀重走 visual tree → frame rate 崩。瀏覽模式因渲染合併網格（每檔 1 個 model）所以順。
|
||||
|
||||
- [x] 量測拾取改打**合併網格** + 三角形頂點 index 反查面（`_mergedFaceRanges` + `ResolveMergedFace` 二分搜尋）
|
||||
- [x] `ApplyRenderMode()` 改為：非剖面（瀏覽＋量測）→ 合併網格；剖面 → 逐面。量測模式不再掛數萬個逐面 model
|
||||
- [x] `BuildMergedMesh` 依面序串接（無焊接共用頂點），匯入時同步記錄每面頂點起始邊界 + `FaceInfo`
|
||||
- [x] 相機暫停事件改訂 `HelixViewport3D.CameraChanged`（控制項層級）＋ `Camera.Changed` 保底，避免相機實例被換掉時訂閱孤兒化
|
||||
- [x] 驗證：WPF 3D hit-test 純幾何不剔背面 → 打單面合併網格仍命中孔內壁；圓/面/邊/角度/面距/剖面量測數值與逐面一致
|
||||
|
||||
**驗收：** 大組件量測模式下轉動視角與瀏覽同樣流暢；圓孔/面/邊/角度/面距量測精度不變；剖面模式量測仍正常

## 開發慣例
|
||||
|
||||
- MVVM：邏輯寫 ViewModel/Service，code-behind 只做純 View 事件（滑鼠拾取轉發）
|
||||
- 一個 B-rep Face = 一個 `GeometryModel3D`，用 `Dictionary<Model3D, FaceInfo>` 反查（量測拾取靠這個，**不可移除逐面結構**）
|
||||
- 渲染雙模式（降 draw call）：每個 leaf 同時持有 `FacesContent`（逐面，量測用）與 `MergedContent`（整零件合併成 1 個 `GeometryModel3D`，瀏覽用）。
|
||||
`ApplyRenderMode()` 依狀態切 `BodyVisual.Content`：**瀏覽(None)且未剖面 → 合併網格**；量測模式或剖面 → 逐面。
|
||||
合併網格只代表「未剖切、目前位置」幾何；平移後呼叫 `RebuildMerged(leaf)` 同步。`_faceMap`/量測/剖面/干涉一律走 `FacesContent`，與目前顯示哪種內容無關
|
||||
- 合併網格的 `BackMaterial`：封閉實體（`SolidCount≥1` 且 `HasBrep`）**不設**（WPF 兩面渲染成本砍半）；開放殼/STL 才設。逐面 `FacesContent` 一律保留 BackMaterial（剖切要看內部）

|
||||
`BuildMergedMesh` 依面序串接（`baseIdx += positions.Count`，無焊接共用頂點），故命中 `RayHit.VertexIndex1` 可二分搜尋（`ResolveMergedFace`）回是哪個面。
|
||||
**這是 v0.3.2 修大檔量測卡頓的關鍵**：量測模式不再掛數萬個逐面 `GeometryModel3D`（64k 面實測 = 64k draw call，轉動/停下重繪爆量）→ 改成每檔 1 個 model，量測模式 orbit 與瀏覽同樣順。
|
||||
邊界由面頂點數決定、平移不改 → 永久有效，`RebuildMerged` 不需重算。**不要因為「量測要逐面」而把渲染改回逐面**

## ✨ Features
|
||||
|
||||
Open mechanical STEP parts for quick review and measurement without a heavyweight CAD suite (SolidWorks / Creo).
|
||||
|
||||
- **Multi-file import** — STEP / STL / DXF, via the toolbar (multi-select), drag-and-drop, or command line: `STPViewer.exe a.stp b.stl`
|
||||
- **Assembly tree** — STEP product structure restored as a tree (assembly → part); per-node show/hide, recolor (cascades to children), zoom-to; file-level remove and outline-edge toggle
|
||||
- **Measurement** (toolbar mode toggle, then click the model):
|
||||
|
||||
| Mode | Output |
|
||||
|---|---|
|
||||
| 📍 點 | XYZ 座標（自動吸附鄰近 B-rep 頂點） |
|
||||
| 📏 距離 | 兩點直線距離 + ΔX/ΔY/ΔZ |
|
||||
| 📐 邊 | 直線長 / 曲線長 / 圓弧長+半徑 |
|
||||
| ⬛ 面 | 面積（網格近似）+ 曲面類型（平面法向量、圓柱半徑/軸向） |
|
||||
| ⭕ 圓 | 圓心 / 半徑 / 直徑 / 周長 |
|
||||
| ∠ 角度 | 兩面（法向量）/ 兩直線邊 夾角 + 補角 |
|
||||
| ⇔ 面距 | 面到面最短距離（網格近似）+ 最近點對 |
|
||||
| ⤚ 對齊 | 點「要移動零件」一點 + 目標點 → 純平移該檔案使兩點貼合（B-rep 整體位移） |
|
||||
| 🎯 三點 | 來源檔 3 特徵點 + 目標檔 3 對應點 → 旋轉+平移一次貼合（方向不同也能對） |
|
||||
- **旋轉**：樹面板選檔案 + 工具列 ↻X/↻Y/↻Z 繞中心 +90°（擺正方向用，連按累加）
|
||||
- **拖曳** 🖐：手形游標模式，左鍵按住零件沿螢幕平面拖動、放開定位（粗定位用；精確貼合用對齊）；右鍵轉視角不受影響
|
||||
- **操作器** ⊹：樹面板選檔案 → 顯示 XYZ 三色箭頭 + 旋轉環（Fusion 360 風格）；拖箭頭沿該軸移動（與視角無關，適合沿插合軸推進）、拖環繞軸轉任意角度，放開即定位。操作器永遠浮在最上層、不被實體遮擋
|
||||
- **干涉檢查** 🧩：勾選剛好 2 個可見檔案 → 相交時顯示紅色干涉交線 + 相交三角形對數；無相交時回報最小間隙 gap（gap≈0 即為配合 match，共面貼合不算干涉）
|
||||
- **剖面**：✂ 開關 + X/Y/Z 軸 + 位置滑桿 + 反向；CPU 網格裁切，原始幾何保留（量測不受影響）
|
||||
- **單位**：mm ⇄ inch 一鍵切換，既有量測（清單與 3D 標籤）即時換算
|
||||
- **匯出**：量測結果 CSV（Excel 中文不亂碼）、3D 視圖 PNG 截圖（2x 解析度）
|
||||
- **視角**：右鍵旋轉、滾輪縮放、中鍵平移、ViewCube
|
||||
| 📍 Point | XYZ coordinate (auto-snaps to nearby B-rep vertex) |
|
||||
| 📏 Distance | Straight-line distance + ΔX/ΔY/ΔZ |
|
||||
| 📐 Edge | Line length / curve length / arc length + radius |
|
||||
| ⬛ Face | Area (mesh approximation) + surface type (plane normal, cylinder radius/axis) |
|
||||
| ⭕ Circle | Center / radius / diameter / circumference |
|
||||
| ∠ Angle | Angle between two faces (normals) or two straight edges + supplement |
|
||||
| ⇔ Face distance | Shortest face-to-face distance (mesh approximation) + closest point pair |
|
||||
| ⤚ Align (2-pt) | Pick a point on the moving part + a target point → pure translation so the two points coincide |
|
||||
| 🎯 Align (3-pt) | 3 source points + 3 target points → rotation + translation in one shot |
|
||||
|
||||
## 快速開始
|
||||
- **Rotate** — select a file in the tree, then ↻X / ↻Y / ↻Z to rotate +90° about its center (for re-orienting; repeat to accumulate)
|
||||
- **Drag** 🖐 — hand-cursor mode; hold the left button to drag a part along the screen plane, release to place (right-button view orbit unaffected)
|
||||
- **Gizmo** ⊹ — select a file → XYZ tri-color arrows + rotation rings (Fusion 360 style); drag an arrow to move along that axis (view-independent), drag a ring to rotate. Always floats on top, never occluded
|
||||
- **Interference check** 🧩 — with exactly 2 visible files, shows red intersection curves + intersecting triangle-pair count; otherwise reports the minimum gap (gap ≈ 0 means a fit/match; coplanar contact is not interference)
|
||||
- **Section plane** ✂ — X/Y/Z axis + position slider + flip; CPU mesh clipping, original geometry preserved (measurement stays exact)
|
||||
- **Units** — one-click mm ⇄ inch; existing measurements (list + 3D labels) convert live
|
||||
- **Export** — measurement results to CSV (UTF-8 BOM, no mojibake in Excel) and a 2× PNG screenshot of the 3D view
|
||||
- **View** — right-button orbit, wheel zoom, middle-button pan, ViewCube
|
||||
|
||||
Measurement principle: edge length, circle radius and angles use **exact B-rep values**; area is a triangle-mesh sum approximation (triangulation precision adapts to model size, 0.02–0.5 mm).

## 💻 System Requirements
|
||||
|
||||
| Item | Requirement |
|
||||
|------|-------------|
|
||||
| OS | Windows 10 / 11 (x64) |
|
||||
| Runtime | .NET 8 Desktop Runtime (framework-dependent build) — or none for the portable build |
|
||||
| Build SDK | .NET 8 SDK (only to build from source) |
|
||||
|
||||
---
|
||||
|
||||
## 📥 Installation
|
||||
|
||||
Download a release build and run it — no install required.
|
||||
|
||||
- **Framework-dependent** (smaller): requires the .NET 8 Desktop Runtime. Run `STPViewer v0.3.2.exe`.
|
||||
- **Portable** (self-contained): runtime bundled, no install / admin. Run `STPViewer v0.3.2.exe`.
|
||||
|
||||
Or build from source (see below).
|
||||
|
||||
```bash
|
||||
git clone https://github.com/ETWen/STPViewer.git
|
||||
cd STPViewer
|
||||
dotnet build STPViewer.sln
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
```bash
|
||||
# Build and run
|
||||
dotnet build STPViewer.sln
|
||||
dotnet run --project src/STPViewer
|
||||
|
||||
# 發佈免安裝資料夾
|
||||
# Publish a no-install folder
|
||||
dotnet publish src/STPViewer -c Release -o publish/STPViewer
|
||||
```
|
||||
|
||||
無 UI 匯入管線與幾何數學驗證：
|
||||
Then import a `.stp` file (toolbar **Import**, drag-and-drop, or command-line argument), pick a measurement mode, and click the model.
|
||||
|
||||
---
|
||||
|
||||
## 📚 Usage Guide
|
||||
|
||||
1. **Import** one or more CAD files. Each file becomes a root in the assembly tree and the view zooms to fit.
|
||||
2. **Navigate** the tree — toggle visibility, recolor, zoom to a node, or remove a file.
|
||||
3. **Measure** — pick a mode on the toolbar (Point / Distance / Edge / Face / Circle / Angle / Face-distance), then click the model. Results appear in the right-hand panel; delete individually or clear all.
|
||||
4. **Assemble** — use Align (2-pt / 3-pt), Rotate, Drag, or the Gizmo to position parts; then run the Interference check to verify fit.
|
||||
5. **Section** — toggle ✂, choose an axis, and slide to cut through the model; measurement stays exact on the original geometry.
|
||||
6. **Export** — save measurements to CSV or capture a 2× PNG of the view.
|
||||
|
||||
Headless import-pipeline and geometry-math verification (no UI):
|
||||
|
||||
```bash
|
||||
dotnet run --project tools/SmokeTest -- "path\to\model.stp" # 匯入 + 裝配樹
|
||||
dotnet run --project tools/SmokeTest -- --clip-test # 剖切裁切數學
|
||||
dotnet run --project tools/SmokeTest -- --interference-test # 干涉 相交/分離/貼合
|
||||
dotnet run --project tools/SmokeTest -- --align-test # 三點對齊剛體變換數學
|
||||
dotnet run --project tools/SmokeTest -- "path\to\model.stp" # import + assembly tree
|
||||
dotnet run --project tools/SmokeTest -- --clip-test # section clipping math
|
||||
dotnet run --project tools/SmokeTest -- --interference-test # interference: intersect / separate / contact
|
||||
dotnet run --project tools/SmokeTest -- --align-test # 3-point rigid-transform math
|
||||

## 🔨 Building from Source
|
||||
|
||||
量測原則：邊長、圓半徑等取 **B-rep 精確值**；面積為三角網格加總近似（三角化精度依模型尺寸自適應 0.02–0.5 mm）。
|
||||
```bash
|
||||
dotnet build STPViewer.sln -c Debug
|
||||
dotnet run --project src/STPViewer
|
||||
dotnet publish src/STPViewer -c Release -o publish/STPViewer
|
||||
```
|
||||
|
||||
## 已知限制
|
||||
NuGet dependencies (restored automatically): `CADability`, `HelixToolkit.Wpf`, `CommunityToolkit.Mvvm`.
|
||||
|
||||
- 大型 STEP（數千面）匯入需數十秒（CADability 解析成本），匯入期間 UI 有進度提示不凍結
|
||||
- 輪廓邊線超過 30,000 線段的檔案預設關閉邊線（WPF LinesVisual3D 轉動視角時效能限制），可在樹面板手動開啟
|
||||
- **IGES 不支援**（CADability 無 IGES reader）；STL 無 B-rep，僅支援 點/距離/角度/面距 量測；DXF 為線架構檢視
|
||||
- 剖切面無封口（cap），剖開處顯示內部背面材質（深灰）
|
||||
- 面積與面距為三角網格近似值；邊長/圓半徑/角度為 B-rep 精確值
|
||||
- 少數 AP242 檔案 CADability 支援不完整，匯入失敗會提示訊息（不閃退）
|
||||
- 唯讀檢視器，不寫入/修改原始檔案

|

## ⚠️ Known Limitations
|
||||
|
||||
- Large STEP files (thousands of faces) take tens of seconds to import (CADability parse cost); a progress indicator keeps the UI responsive.
|
||||
- Files with more than 30,000 outline segments disable edges by default (WPF `LinesVisual3D` cost while orbiting); re-enable per file in the tree.
|
||||
- **IGES is not supported** (CADability has no IGES reader). STL has no B-rep (point / distance / angle / face-distance only). DXF is wireframe view.
|
||||
- Section cuts have no cap fill — the opened face shows the interior back material (dark gray).
|
||||
- Area and face-distance are mesh approximations; edge length / circle radius / angle are exact B-rep values.
|
||||
- A few AP242 files are incompletely supported by CADability; failed imports show a message (no crash).
|
||||
- Read-only viewer — never writes to or modifies the source file.

## 📜 Version History
|
||||
|
||||
### v0.3.2
|
||||
|
||||
- **Perf:** large-assembly measurement no longer lags while orbiting. Measurement modes now render the merged mesh (one model per file) and resolve the picked face from the hit triangle's vertex index, instead of rendering tens of thousands of per-face models. Per-face rendering is kept only for section mode.
|
||||
- Camera-interaction suspension now also subscribes to `HelixViewport3D.CameraChanged` so it can't be orphaned if the camera instance is replaced.
|
||||
|
||||
### v0.3.1
|
||||
|
||||
- Gizmo always-on-top overlay (manipulator floats above parts, never occluded).
|
||||
|
||||
### v0.3.0
|
||||
|
||||
- Rotation alignment: axis rotate (↻X/↻Y/↻Z), 3-point align, and the unified `TransformRoot` rigid-transform path.
|
||||
|
||||
### v0.2.x
|
||||
|
||||
- Drag mode, 2-point align, interference check, section plane, angle / face-distance measurement, assembly tree, STL / DXF support, mm ⇄ inch.

|
||||
## ✨ 功能特色
|
||||
|
||||
快速開啟機構件 STEP 檔做確認與量測，不需安裝 SolidWorks / Creo 等重量級 CAD。
|
||||
|
||||
- **多檔匯入** — STEP / STL / DXF，工具列匯入（可複選）、拖放到視窗，或命令列 `STPViewer.exe a.stp b.stl`
|
||||
- **裝配樹** — STEP product structure 還原成樹（組件→零件）；逐節點 顯示/隱藏、換色（cascade）、Zoom-to；檔案層級可移除、開關輪廓邊線
|
||||
- **量測**（工具列切換模式，點擊模型）：
|
||||
|
||||
| 模式 | 輸出 |
|
||||
|---|---|
|
||||
| 📍 點 | XYZ 座標（自動吸附鄰近 B-rep 頂點） |
|
||||
| 📏 距離 | 兩點直線距離 + ΔX/ΔY/ΔZ |
|
||||
| 📐 邊 | 直線長 / 曲線長 / 圓弧長 + 半徑 |
|
||||
| ⬛ 面 | 面積（網格近似）+ 曲面類型（平面法向量、圓柱半徑/軸向） |
|
||||
| ⭕ 圓 | 圓心 / 半徑 / 直徑 / 周長 |
|
||||
| ∠ 角度 | 兩面（法向量）/ 兩直線邊 夾角 + 補角 |
|
||||
| ⇔ 面距 | 面到面最短距離（網格近似）+ 最近點對 |
|
||||
| ⤚ 對齊（兩點） | 點「要移動零件」一點 + 目標點 → 純平移使兩點貼合 |
|
||||
| 🎯 對齊（三點） | 來源檔 3 點 + 目標檔 3 對應點 → 旋轉+平移一次貼合 |
|
||||
|
||||
- **旋轉** — 樹面板選檔案 + 工具列 ↻X/↻Y/↻Z 繞中心 +90°（擺正方向用，連按累加）
|
||||
- **拖曳** 🖐 — 手形游標模式，左鍵按住零件沿螢幕平面拖動、放開定位（右鍵轉視角不受影響）
|
||||
- **操作器** ⊹ — 樹面板選檔案 → XYZ 三色箭頭 + 旋轉環（Fusion 360 風格）；拖箭頭沿該軸移動（與視角無關）、拖環繞軸轉。永遠浮在最上層、不被實體遮擋
|
||||
- **干涉檢查** 🧩 — 勾選剛好 2 個可見檔案 → 相交時顯示紅色干涉交線 + 相交三角形對數；無相交時回報最小間隙 gap（gap≈0 即為配合 match，共面貼合不算干涉）
|
||||
- **剖面** ✂ — X/Y/Z 軸 + 位置滑桿 + 反向；CPU 網格裁切，原始幾何保留（量測仍精確）
|
||||
- **單位** — mm ⇄ inch 一鍵切換，既有量測（清單與 3D 標籤）即時換算
|
||||
- **匯出** — 量測結果 CSV（UTF-8 BOM，Excel 中文不亂碼）、3D 視圖 2× PNG 截圖
|
||||
- **視角** — 右鍵旋轉、滾輪縮放、中鍵平移、ViewCube
|
||||
|
||||
量測原則：邊長、圓半徑、角度取 **B-rep 精確值**；面積為三角網格加總近似（三角化精度依模型尺寸自適應 0.02–0.5 mm）。

|
||||
|
||||
## 📥 安裝
|
||||
|
||||
下載發佈版直接執行，免安裝。
|
||||
|
||||
- **框架相依版**（檔案較小）：需 .NET 8 Desktop Runtime，執行 `STPViewer v0.3.2.exe`。
|
||||
- **Portable 版**（self-contained）：內含 runtime，免安裝 / 免系統管理員，執行 `STPViewer v0.3.2.exe`。
|
||||
|
||||
或從原始碼建置（見下）。
|
||||
|
||||
```bash
|
||||
git clone https://github.com/ETWen/STPViewer.git
|
||||
cd STPViewer
|
||||
dotnet build STPViewer.sln
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 快速開始
|
||||
|
||||
```bash
|
||||
# 建置並執行
|
||||
dotnet build STPViewer.sln
|
||||
dotnet run --project src/STPViewer
|
||||
|
||||
# 發佈免安裝資料夾
|
||||
dotnet publish src/STPViewer -c Release -o publish/STPViewer
|
||||
```
|
||||
|
||||
接著匯入 `.stp` 檔（工具列「匯入」、拖放、或命令列帶檔），選一個量測模式，點擊模型即可。
|
||||
|
||||
---
|
||||
|
||||
## 📚 使用指南
|
||||
|
||||
1. **匯入** 一個或多個 CAD 檔，每個檔案成為裝配樹的一個 root，視角自動 Zoom 到全景。
|
||||
2. **操作樹** — 顯示/隱藏、換色、Zoom-to 某節點，或移除檔案。
|
||||
3. **量測** — 工具列選模式（點 / 距離 / 邊 / 面 / 圓 / 角度 / 面距），點擊模型；結果顯示於右側面板，可單筆刪除或全部清除。
|
||||
4. **裝配** — 用 對齊（兩點/三點）、旋轉、拖曳、操作器擺位，再用干涉檢查驗證配合。
|
||||
5. **剖面** — 開啟 ✂、選軸向、滑動剖切；量測仍以原始幾何精確計算。
|
||||
6. **匯出** — 量測結果存 CSV，或截 2× PNG。
|
||||
|
||||
無 UI 匯入管線與幾何數學驗證：
|
||||
|
||||
```bash
|
||||
dotnet run --project tools/SmokeTest -- "path\to\model.stp" # 匯入 + 裝配樹
|
||||
dotnet run --project tools/SmokeTest -- --clip-test # 剖切裁切數學
|
||||
dotnet run --project tools/SmokeTest -- --interference-test # 干涉 相交/分離/貼合
|
||||
dotnet run --project tools/SmokeTest -- --align-test # 三點對齊剛體變換數學
|
||||
```
|
||||

# v0.3.1 — First public release: 3D STEP viewer with measurement & assembly fit-check
|
||||
|
||||
A lightweight Windows desktop viewer for STEP / STL / DXF — open a part, measure it,
|
||||
and check how two parts fit together, without firing up a heavyweight CAD suite.
|
||||
|
||||
## ✨ New features
|
||||
|
||||
**View & assembly tree**
|
||||
* Import multiple CAD files at once (STEP / STL / DXF) via the toolbar, drag-and-drop,
|
||||
or the command line (`STPViewer.exe a.stp b.stp`).
|
||||
* STEP product structure is rebuilt into an **assembly tree** — toggle visibility, recolor
|
||||
(cascades to children), and zoom-to any node; whole-file remove and outline-edge toggle.
|
||||
* Smooth orbit / zoom / pan even on large assemblies (hundreds of thousands of triangles).
|
||||
|
||||
**Measurement** (pick a mode, click the model)
|
||||
* Point (snaps to nearby vertices), two-point distance + ΔX/ΔY/ΔZ, edge length
|
||||
(line / curve / arc with radius), face area + surface type, circle center / radius /
|
||||
diameter / circumference, angle between two faces or edges, and face-to-face minimum gap.
|
||||
* Edge length, radius and angle use **exact B-rep values**; area and gap are mesh-based.
|
||||
* Switch units **mm ⇄ inch** anytime — existing measurements and 3D labels convert live.
|
||||
|
||||
**Assembly fit-check** (mate a male/female pair and verify)
|
||||
* **Two-point align** — click a point on the part to move, then the target point, to slide
|
||||
the whole file into place.
|
||||
* **Three-point align** — pick 3 feature points on each file to solve a full rotate+translate
|
||||
in one shot, for parts that aren't already oriented the same way.
|
||||
* **Axis rotate** — rotate the selected file ±90° about X / Y / Z to square it up.
|
||||
* **Drag mode** (hand cursor) — left-press a part and drag it along the screen plane.
|
||||
* **Gizmo** — XYZ arrows to move along an axis (independent of view angle, ideal for pushing
|
||||
along a mating axis) and rings to rotate any angle. The gizmo always renders on top, so it
|
||||
is never hidden inside a solid part.
|
||||
* **Interference check** — for two visible files, shows red intersection lines where they
|
||||
collide, or the minimum gap when they don't (gap ≈ 0 means a clean fit).
|
||||
|
||||
**Section & export**
|
||||
* Section view along X / Y / Z with a position slider and flip, to inspect mating internals.
|
||||
* Export measurements to CSV (opens cleanly in Excel) and save a 2× PNG screenshot of the view.
