The B-rep engine parses your STEP file topology — not just the mesh — to recognize holes, pockets, walls, fillets, bosses, and freeform surfaces. Each feature is evaluated against manufacturability rules covering tool access, depth ratios, wall deflection, setup count, and more.


Geometry-based pricing engine calculates stock size, material removal rate, cycle time (rough + finish), setup count, and applies regional labor rates. See side-by-side comparisons across US, China, Taiwan, and Mexico.
Built by engineers who've spent years at the intersection of design and manufacturing.
Holes, walls, radii, pockets, undercuts, access directions, draft angles, tool reach — the same checks a 30-year CNC veteran runs mentally.
Click any issue and see the exact faces light up on your 3D model. Understand the geometry driving each DFM concern.
US, China, Taiwan, Mexico — get per-region pricing with cycle time breakdowns and material-specific cost factors.
Export professional DFM reports for your shop floor, procurement team, or design review meetings.
Switch between Aluminum, Stainless Steel, Titanium, Delrin, Polycarbonate — watch how DFM severity shifts with material properties.
