Solidworks 2025 Io Loop

SOLIDWORKS 2025 IO Loop

Use this skill for live SOLIDWORKS 2025 work. The active document is the source of truth: perform the requested model change, then read SOLIDWORKS back to prove the result.

Project Boundary

When working under D:\skills\codex\SW2025, this project is isolated. Use this skill, its bundled scripts, and this project's docs/ knowledge base as the authority. Do not silently import assumptions, scripts, shortcut mappings, macro conclusions, or validation results from other projects. Use outside material only when explicitly requested, and verify the result against live SOLIDWORKS 2025 or this local project before making it reusable here.

First Move

1. Attach to the running app with SldWorks.Application; do not launch SOLIDWORKS unless the user asks.
2. Prefer the unified runner:

python ".\skills\solidworks-2025-io-loop\scripts\solidworks_sw2025.py" <command> [options]

3. For geometry edits, verify by counting bodies, faces, sketch segments, created circles, or matching model edges after the feature is built.
4. If a script reports partial creation, do not cut or continue silently; clean the partial sketch and retry with the proven workflow.

Command Map

Proven Workflows

• cube: a 100 mm cube should read back as one body, six faces, 1,000,000 mm^3 volume, and 60,000 mm^2 area.
• extract-selection: accepts selected edges, faces, or solid bodies and makes a 3D sketch from the selected geometry.
• face-centerline: default direction is the selected face normal, not global Z.
• connect-centers: sorts visible solid bodies along X and creates a 3D sketch through their mass centers.
• circle-flange: uses the user's proven AddToDB bulk sketch pattern, then verifies hole_count * 2 circular through-hole edges after cutting.
• rect-flange: places holes along the rectangular perimeter. X/Y counts include corners, so x=8, y=6 creates 8*2 + (6-2)*2 = 24 holes.

Macro Knowledge

Project-level references live under docs/:

• docs/SOLIDWORKS_2025_HELP_KNOWLEDGE.md
• docs/SOLIDWORKS_2025_HELP_INDEX.json
• docs/SOLIDWORKS_SHORTCUTS.md
• docs/solidworks_shortcuts_inventory.json
• docs/SOLIDWORKS_MACRO_KNOWLEDGE.md
• docs/SOLIDWORKS_MACRO_KNOWLEDGE.json
• docs/FLANGE_HOLE_CREATION_RULES.md
• docs/extracted_registered_macros/
• docs/macro_txt/

Before menu-heavy UI work, check the shortcut/macro references first. Useful registered macros include 法兰孔生成, 阵列优化, 公垂线, 点面垂直线段, 多实体重心草图提取, 实体内外轮廓全提取, 实体中心线提取, 合并草图升级, and 2D3D草图缩放.

Treat .swp files as binary VBA containers. Extract source, back up the original macro, and avoid direct binary edits unless the writer is proven safe.

SOLIDWORKS 2025 COM Rules

• Many pywin32 COM members are exposed as properties. Use a helper that accepts both method and property forms before calling fragile APIs.
• Use win32com.client.VARIANT(pythoncom.VT_DISPATCH, None) when SOLIDWORKS selection APIs need a null dispatch.
• model.Extension.CreateMassProperty may be property-like in this environment.
• For flange-hole sketches, ordinary CreateCircle / CreateCircleByRadius can silently miss lower-half positions. Use SetAddToDB(True) plus SetDisplayWhenAdded(False), restore both settings in finally, and read back the model edge count after cutting.
• Keep user-visible output Chinese when reporting model operations, but keep scripts ASCII-safe where possible.
