DGN Export

Exports a Bentley MicroStation DGN file to PDF using Bentley View or MicroStation via COM Interop.

Serialised Task

This task runs through the serialisation queue. Only one instance of this task executes at a time across all concurrent workflows. If multiple workflows reach this task simultaneously, they will queue and execute one at a time.

Purpose

Use this task when a workflow needs to produce a PDF from a DGN drawing — for example, to generate a print-ready output for distribution, to archive a drawing at a specific revision, or to produce consistent plot outputs across a batch of engineering files. Export settings such as paper size, orientation, colour mode, and plot area can be defined directly or via a conditional advanced settings table that selects the appropriate profile based on a drawing property value. Bentley View or MicroStation must be installed on the automation server.

Inputs

Field	Type	Required	Description
Local File Full Path	Text	Yes	Full path to the DGN file to export.
Export Type	Dropdown	Yes	The target output format. Currently only PDF is fully implemented.
Advanced Export Settings	Key-Value Pairs	No	Optional lookup table that maps a control property value to a row of export settings (paper size, orientation, colour mode, etc.). When provided, the node selects the matching row; if no match is found it falls back to the first row. Only relevant for PDF, DWF, and PLT exports.

Visibility Rules

Advanced Export Settings is only shown when Export Type is set to PDF, DWF, or PLT.
