SLDASM Viewer

Purpose & User Intent: provide a fast, browser-based view of SolidWorks assemblies (.sldasm) so engineers, reviewers, and procurement can inspect geometry, subassemblies, and BOM relationships without CAD software. When to use: during design reviews, supplier qualification, change-management, and sharing with non-CAD stakeholders in distributed teams.

Core Logic & Features: Required: file upload of .sldasm (and referenced parts), hierarchical assembly parsing, basic rendering, pan/rotate/zoom, and accurate unit handling. Optional/Advanced: exploded views, measurement tools, BOM extraction, cross-section visualization, rendering quality settings, and offline cache. Distinguish between view-only inspection and measurement/analysis workflows.

Inputs & Outputs: Inputs: sldasm_file (type: file, required), referenced_paths (array of strings, optional), unit_preference (mm or inches, optional), rendering_quality (low/medium/high, optional). Outputs: rendered_view_state (internal), exported_snapshot (image, e.g., PNG, optional), bom_data (JSON, optional).

Algorithms & Calculations: Hierarchy traversal of assemblies and parts; build scene graph with transform matrices; compute exploded transform per user-selected step; detect bounding boxes for spatial queries; coordinate unit conversion; precision-aware distance calculations for measurements. No external network calc required.

Error & Edge Cases: Unsupported file format or missing referenced files: report as missing data, degrade gracefully. Large assemblies may time out; apply progressive loading or level-of-detail simplification. Units mismatch triggers automatic conversion with user override. Incomplete BOM data handled as partially populated outputs.

Industry/Region & Localization: Default to metric units (mm) with optional inches, respect standard SolidWorks naming; formatting respects decimal separators by locale if provided. Data export uses standard JSON/CSV BOM formats when requested.

Assumptions & Exclusions: Assume the primary intent is to view and analyze assemblies, not to edit geometry or simulate physics. Exclude full CAD editing, proprietary secure data handling, or offline file persistence beyond browser storage. Assumption: the keyword intent is to enable browser-based viewing of SLDASM files for collaboration and review; not format conversion or advanced engineering calculations.
