Online Bentley DGN to AutoCAD DWG Layer Converter

Direct navigation to objective in-depth evaluation and anti-audit.

Why Do You Need Professional Evaluation?

Bentley MicroStation DGN When converting drawings to AutoCAD DWG drawings, Since the base principles of the two platforms are completely different, this usually results in MicroStation 's level (Levels) 'Unable to snap to CAD' layer (Layers) ', Proprietary cell libraries (Cells) degenerate into broken line segments, and the collapse of Bentley’s signature handwritten continuous line style.

⚠️

Enterprise Security & Anti-Piracy Compliance Warning

DGN The format is generally used in infrastructure design such as national large bridges, rail transit and municipal network management., Involves extremely strict physical security and project sensitivity. Please give priority to use MicroStation Local built-in 'Save as DWG'Function to perform high-precision matching and mount a regular layer comparison table (CSV) , Avoid using public conversion websites for high-volume conversions.

Enterprise Data Conversion Best Practices Guide

01

Mount the Remap CSV mapping file

When exporting from MicroStation, Configure .csv control table, Specify Levels, Colors, LineWeights one by one as the corresponding CAD Layers and Standard Color Index (ACI).

02

Handling Shared Cells

In the export options, change'Shared unit' expands to normal'Blocks', prevents the AutoCAD The drawing was destroyed into sporadic primitives.

03

Uniformly use True Color

Avoid using Bentley-specific color tables, Switch element color values to generic RGB true color before conversion, Prevent everything from turning black after importing CAD.

Technical FAQ

Q: Converted primitives show 'OLE container error'What is the reason?

This means that your DGN drawing has external Excel Datasheet or non-vector drawing. CAD is not compatible with this interface, It is recommended to solidify the screenshot into a normal pixel layer in Bentley before exporting..

Q: DGN The V7 and V8 Does the format affect conversion?

Yes. V7 is an old historical version, There are upper limits on file size and number of layers; V8 is 2001 A common 64-bit three-dimensional database format in the future. Before conversion, you need to confirm whether the target DWG platform can recognize the corresponding ODA Drive.
