Built by people who’ve specified profiles for 20 years

Dimviz comes out of two decades in the pultruded-composite and extrusion industry — quoting sections, arguing over wall thickness, chasing weight-per-metre tables and building product catalogs one mismatched screenshot at a time. Two frustrations kept recurring.

First, marketing and engineering never shared a source of truth. The catalog image and the datasheet were made separately, so they drifted — a render that didn’t match the real section, a weight that didn’t match the geometry.

Second, the new wave of AI 3D tools guesses. That’s fine for a game asset and unacceptable for a part an engineer has to specify. A profile isn’t a creative object — it’s a fixed cross-section swept along a straight line, and its geometry, weight and stiffness are exact.

Our one principle: deterministic geometry

Everything Dimviz produces — the render, the dimensioned drawing, the section properties — is derived from the same polygon with the same math a structural engineer trusts (Green’s theorem for the section, closed-form for circles). One input, and the picture and the numbers can never disagree.

We’re deliberately narrow. We don’t chase photorealism or arbitrary 3D; we do one thing — dimension-true assets for profiles — better than a general tool can. The section is the source of truth, and we keep it that way.

Honest about limits

Computed properties exclude root fillets (a conservative sub-2% effect) and report angle axes as geometric, not principal. Photo input is a perspective-corrected reconstruction calibrated to one dimension you confirm — never a claim of sub-millimetre precision from a phone. Always verify against certified data before release. We’d rather under-claim and be trusted.
