STEP Files vs Native SolidWorks: Why Fabricators Rebuild Instead of Convert

A customer sends you a .stp file. It’s a sheet metal part — clearly visible bends, uniform thickness, nothing exotic. You import it into SolidWorks, run Convert to Sheet Metal, and SolidWorks does… something. A flat pattern appears. You run the DXF export and send it to the laser table. Then the first batch comes back wrong: the developed length doesn’t match the customer’s tolerance, some bends are reversed, and the corner relief geometry is completely off. ...

CAD Interoperability: Why It Matters and How to Achieve It

The Real Cost of CAD Data Silos You design in SolidWorks. Your supplier uses Inventor. The fabrication shop runs AutoCAD. Your client wants STEP files, but their downstream partner needs DXFs with specific bend line formatting. Sound familiar? CAD interoperability isn’t just a technical challenge—it’s a business problem that costs engineering teams hours of manual work, creates fabrication delays, and introduces errors that ripple through entire supply chains. When CAD data can’t move cleanly between systems, engineers spend time in export dialogs instead of designing. Fabrication shops get files missing critical metadata. Projects stall while teams manually convert formats and fix translation errors. ...
