What it does

Everything an engineer
actually needs

From headless CAD geometry to bulk weight spreadsheets, in one tool.

Exact 3D Geometry
CAD's OCCT kernel generates true B-Rep solid geometry — not approximated meshes. Every chamfer, fillet, and thread helix is mathematically exact.

Bulk Weight Calc
Upload a CSV with up to 50 fastener rows — ASME, ISO, DIN — and get exact weights back in seconds. Perfect for BOM costing.
CSV in · CSV out
Custom Configurator
Override pitch, thread length, and material for any standard. Generate a parametric 2D engineering drawing alongside the 3D model.

Workflow

Three steps to
production geometry

01
Select Standard & Size
Pick any fastener type across ASME, ISO, or DIN. Choose diameter and length from the exact standard-specified range.
02
CAD Builds It
CAD spawns, runs with exact OCCT BRep geometry, and returns weight, volume, and exports.
03
Export & Use
Download STEP for SolidWorks / Fusion 360, IGES for legacy CAD, or stream the STL directly into the in-browser 3D viewer.
