MicroStation Development Language
MicroStation Development Language (MDL) is a proprietary programming language used for customizing and extending Bentley Systems' MicroStation CAD software. It enables developers to create custom applications, automate design tasks, and integrate with other systems within the MicroStation environment. MDL is based on C and provides access to MicroStation's API for manipulating drawings, geometry, and user interfaces.
Developers should learn MDL when working extensively with Bentley MicroStation for civil engineering, architecture, or infrastructure projects that require custom tools or automation. It is essential for creating plugins, automating repetitive design tasks, and developing specialized applications that integrate seamlessly with MicroStation's workflow. Use cases include custom drawing generation, data extraction from CAD files, and building industry-specific design tools.
