- CAD users, bookkeepers, designers, and data wranglers
- Worth noticing
- STEP conversion uses Open CASCADE compiled to WebAssembly; Pantone matching is explicitly approximate.
Field notes
The homepage organizes twelve named conversion routes into CAD, banking, color, and structured-data groups. Some tools require small pieces of user input beyond the file itself, such as matching CSV columns, naming QuickBooks accounts, selecting an XML row element, or choosing mesh fineness. The CAD section notes that STEP reading uses Open CASCADE compiled to WebAssembly, while the color section explicitly warns that its nearest Pantone references are approximate.
