VendorCAD vs PDF / email quoting for custom parts

The manufacturer problem

A custom size hits email or phone. Engineering opens CAD and redraws. The quote sits while the buyer shops other shops. Each supplier interprets a long dimension PDF differently. By the time a STEP returns — if it returns — the lead may already be designed around a faster supplier.

Side-by-side

Step	PDF / email quoting	With VendorCAD
Capture intent	Email thread + PDF dimensions	Branded configure link
Geometry	Redraw later in CAD	Live 3D preview as parameters change
Validity	Often discovered late	Invalid configurations blocked before export
File to buyer	Maybe a STEP, maybe later	Manufacturing STEP when validation passes
Quote payload	Ambiguous notes	Exact configuration into the App inbox
Branding	Manufacturer logo in email signature	Buyer-facing link shows manufacturer brand

Why “designed in” matters

Buyers keep designing in their assembly. The supplier who delivers a correct model file first gets locked into the design. VendorCAD’s lane is that race: see it, get the STEP when rules pass, keep working, quote the exact spec.

Limits to state clearly

VendorCAD does not magically eliminate engineering judgment for every one-off. It is strongest when a product family can be parameterized into a recipe with clear knobs and rules.

Not a fit if…

• Every job is a true one-off with no repeatable family rules
• You only need a static PDF catalog and never intend to publish a configure link
• You want peer-review proof rather than a vendor-owned evaluation page (Trust)
