Getting started

Export from an assembly

What is different when you validate and export from an Onshape assembly rather than a Part Studio.

Same workflow as Part Studios

If you have not run a first export yet, start with Export your first DXF package. The steps are the same whether DXF Exporter is open in a Part Studio or an assembly: run validation, review statuses, generate and preview, then download.

Source documents and access

Assemblies pull parts from other elements and, often, other documents. DXF Exporter needs to read each source document to validate geometry and generate DXFs.

If you cannot open a source document, validation cannot complete for those parts. The app lists the affected part names. Request access from the document owner, or suppress those instances in the assembly tree and revalidate.

Quantities

In a Part Studio, identical part names are treated as separate instances — numbered suffixes such as Panel 1 and Panel 2 — because geometry uniqueness cannot be assumed from the name alone.

In an assembly, repeated inserts of the same configured part under the same parent are rolled up into one row with a quantity. Export filenames use an _xN suffix when quantity is greater than one (for example Panel_x3).

Part naming in nested assemblies

Parts nested in subassemblies or rigid Part Studio inserts inherit parent names as prefixes so labels stay distinct. The prefix chains subassembly names, then the rigid Part Studio insert name when applicable, then the part name.

For example, a part Bracket inside rigid insert Side Panels under subassembly Frame may appear as Frame_Side Panels_Bracket in the validation table and export package.

Validation and generation time

Geometry is evaluated per source document. Assemblies that reference many source documents may take longer to validate and generate than a single Part Studio with the same number of parts, because work is batched by document rather than processed in one pass.
