A Vectorworks lighting plot exports straight into a previs engine

The picture

Vectorworks Spotlight is stage and lighting design software from Vectorworks, part of the Nemetschek Group; Vision is its companion previsualization application. A company newsroom article dated 26 October 2023, written by Vectorworks staff, describes how a design built in Spotlight exports as a My Virtual Rig, or MVR, file that carries General Device Type Format, or GDTF, fixture data into Vision for previsualization. The Spotlight product page, a living document as retrieved on 16 September 2026, states that patching a show and exporting that data through GDTF and MVR also generates equipment-list worksheets and, separately, automatically updated build drawings and light plots.

What the documents show

The 2023 article is specific about one capability added with the Vectorworks 2024 release: Vision's virtual projectors were updated to run, in the company's words, the same lighting algorithm found in Vision lighting devices, which the article says lets a designer check shadows, color temperature, focus and keystoning before installation. That is a stated software capability, not an independently measured accuracy result. The Spotlight page's claim that plots and schedules are auto-generated from the same drafted data describes a documentation workflow; it does not state that the auto-linked schedule has been checked against the physical instruments a crew will actually hang, and this entry does not read it that way. The two pages together establish a data pipeline, GDTF and MVR, but neither claims the pipeline guarantees the fixture data itself is correct for a given rig.

What it is allowed to decide

On these sources, the Spotlight-to-Vision pairing can plausibly support decision class 5, technical execution, because the MVR export is described as carrying patch and channel data directly usable for programming, not only a picture for approval. It holds Auditability, since Spotlight's documentation is stated to regenerate automatically as the design changes, keeping the record and the drawing synchronized. It does not, on this reading, establish independent Photometric authority: the lighting algorithm claim describes the previs engine's method, not a verification step confirming that the GDTF profile in use matches the physical fixture on a truss.

The disclosure label

A disclosure for a Vision previs image built from a Spotlight export, dated 16 September 2026 and asserted by the show's lighting designer, would read: this is a class 5 technical-execution previs generated via GDTF and MVR from Vectorworks Spotlight; it holds Auditability, since the plot and schedule regenerate from the same data; it does NOT HOLD confirmed Photometric authority beyond the accuracy of the specific fixture profile selected for the export.

• Was the GDTF profile in the MVR export supplied by the fixture's manufacturer or built or edited in-house?
• Does the auto-generated schedule get checked against the rig as hung, or only against the drawing?
• Which Vectorworks release produced this file, since the projector lighting-algorithm feature is tied to a specific version?

An auto-linked schedule removes one kind of error, a manual transcription mistake between plot and paperwork, while leaving untouched the separate question of whether the data it carries describes the instrument actually on site.
