CAD Exchange, File Formats & Release
A CAD handoff hub for STEP, STL, 3MF, IGES, robust parametric models and manufacturing release packages.
Start with the design logic
A manufacturing release is more than one CAD file. The design master, neutral exchange file, drawing and process-specific exports must represent the same revision and the same design intent.
STEP vs STL vs 3MF
Choose between exact B-rep exchange and mesh/additive formats.
Open →STEP vs IGES
Understand why modern solid exchange usually favors STEP over legacy surface exchange.
Open →Solid vs Surface Modeling
Use each modeling approach where it best supports geometry and downstream validation.
Open →Robust Parametric CAD
Reduce fragile references and preserve design intent.
Open →Manufacturing Handoff
Release the native model, neutral format, drawing and process-specific exports coherently.
Open →Drawing Release Checklist
Make the released drawing agree with the actual CAD revision.
Open →Drawing Release Assistant
Run a structured release review before sending files out.
Open →Use DIVE-LD as a workflow
Read the concept, use a transparent calculator where useful, then verify the actual design against material data, process capability, supplier feedback and the standards that govern the release.
