Parameters

Parameters are the values a published configurator may change. Everything else stays locked in the Fusion master.

What to expose

Expose only the dimensions and options that change from quote to quote — length, diameter, pitch, material grade, accessory flags. Keep manufacturing constants and internal sketch names off the buyer form.

Each parameter needs:

  • A stable key that matches the Fusion parameter name
  • A type (number, enum, boolean)
  • Units when it is a dimension
  • Min / max or allowed values
  • A label sales can read out loud

Mapping to Fusion

The App key must match the parameter in the .f3d. A mismatch fails the generate job instead of silently ignoring the slider.

Prefer explicit units in the key or label (length_in, length_mm) so inbound quotes stay unambiguous.

Frozen spec

When a buyer submits a quote or downloads an allowed output, VendorCAD freezes the parameter set and hashes it. That frozen record is what engineering and the inbox see — not a screenshot of a slider.

{
  length_in: 120,
  diameter_in: 9,
  pitch_in: 9,
  units: "in"
}
