A plain-English introduction to Geometric Dimensioning and Tolerancing. Learn datums, feature control frames, and the core GD&T symbols that control fit, function, and cost on real engineering drawings.

A 2D drawing isn’t a 3D model. Here’s how engineers convert legacy prints, scans, and physical samples into validated, manufacturable STEP files — and where it goes wrong.
How post-tension strand sheathing gets stripped in the field, why it’s harder and riskier than it looks, and the depth-controlled tool PartSnap is developing.
TPLO is one of the most common — and most variable — orthopedic surgeries in veterinary medicine. A patient-specific 3D printed tibia, in the surgeon’s hand the day before the procedure, changes the conversation.
DFM is where prototype budgets are won or lost. Twelve concrete decisions — tolerances, materials, geometry, finishes — that move parts from $400 each to $40 each without changing what the part does.
Confused about provisional vs. non-provisional patents? Here’s a clear, practical breakdown of what each one does, what it costs, and which you should file first.
Need to recreate a part with no drawings? Learn how reverse engineering services turn physical parts into manufacturable CAD models — and when it’s worth the investment.
Geometric Dimensioning and Tolerancing made practical for inventors. The five concepts that matter, the mistakes that cost money, and how to get drawings that machinists actually love.
A practical engineer’s guide to using topology optimization with additive manufacturing — when it pays off, where it fails, and the workflow that delivers 30-60% weight savings without losing structural performance.
Hand calculations cover 80% of engineering problems. FEA handles the other 20% — complex geometry, stress concentrations, combined loading, and code compliance. Learn when you need FEA and what a licensed P.E. brings to the analysis.
