MicroStation Python API

MicroStation Python API is a powerful tool that allows developers to extend the functionality of MicroStation and various MicroStation-based applications. It enables seamless integration of high-quality applications with MicroStation and other Bentley products and is the recommended method for accessing Bentley DGN files with full fidelity.

MicroStation and Bentley applications platform APIs can be used to develop a range of applications, from simple utilities to sophisticated commercial solutions, and supports a variety of programming languages including C, C++, C#, Python, and Visual Basic.

You can find more about it in the MicroStation Python API documentation.

API Presentations
API presentations give, an overview of the MicroStation Python API components and then dives into more details for each aspect of the API.

Example Scripts

Example Scripts are delivered under the following directory C:\ProgramData\Bentley\PowerplatformPython\Examples\MicroStation\

The quickest way to start using Python in MicroStation is to use the Python Manager dialog on the Utilities tab of either the Drawing or Modelling Ribbon. Load Python from the examples directory and then run it.

Example Wikis, Blogs
To help you get started, we have created a series of Wikis, Blogs that cover everything from installation to advanced scripting. Dive in and explore the new possibilities with MicroStation Python!
