CAD is more than creating geometry
Model structure, data exchange, drawings and downstream manufacturing requirements determine whether a CAD model is actually useful.
From model intent to release
Six guides covering neutral formats, robust parametric modeling and manufacturing handoff.
STEP vs STL vs 3MF
Compare STEP, STL and 3MF for CAD exchange, manufacturing and 3D printing.
CAD · File formatsSTEP vs IGES for CAD Exchange
Compare STEP and IGES for transferring solid, surface and product geometry between CAD systems.
CAD · ModelingSolid vs Surface Modeling in CAD
Understand when solid modeling, surface modeling and hybrid workflows are appropriate in mechanical design.
CAD · Parametric modelingHow to Build More Robust Parametric CAD Models
Practical habits for stable feature trees, references, design intent and easier engineering changes.
CAD · WorkflowHow to Prepare a CAD Model for Manufacturing
A release checklist for cleaning, validating and packaging CAD before sending it to a manufacturer.
CAD · DrawingsEngineering Drawing Release Checklist
A practical checklist for releasing manufacturing drawings with clear dimensions, tolerances and requirements.
Follow a complete learning path
Use a topic hub when you want connected guides, tools and verification steps rather than a single article.
Use the Design Handbook as your map
Move from requirements and process selection through DFM, GD&T and final drawing release.
