Definition
In MicroStation, Cells & Shared Cells provides a foundational technical capability. MicroStation's equivalent of CAD blocks. Cell libraries host static or parametric components, while Shared Cells optimize file memory by referencing one definition.
Why it matters
Getting Cells & Shared Cells right from the start prevents compounding errors through the rest of the design process. Minimizes file size when drawing massive infrastructure plans containing thousands of standardized signposts or rail fittings.
Common pitfalls
- Modifying cell library paths, causing placed cells to lose their source definitions.
- Broken nested cells.
MicroStation Ecosystem Context
This concept is a core structural element of the MicroStation drafting and engineering environment developed by Bentley Systems. Bentley's foundational high-performance CAD and BIM platform for large-scale global infrastructure projects.
Relevant MicroStation FAQs
❓ What is the recommended practice for MicroStation DGN Design File Format?
DGN V8 supports unlimited levels, multiple models within one file, and embedded raster references. Set working units (master units, sub-units, resolution) at file creation—changing later risks precision loss. Use the 'Compress Design' tool periodically to remove unused elements and reduce file size.
❓ What is the recommended practice for MicroStation Cells & Shared Cells?
Create cells for repeated elements (symbols, details, equipment). Shared cells store geometry once and reference it multiple times—editing the shared definition updates all instances. Organize cells in .cel libraries by discipline. Use point cells for single-insertion-point symbols, graphic cells for multi-element groups.
❓ What is the recommended practice for MicroStation Levels & Level Manager?
Organize elements on named levels with assigned colors, line styles, and weights. Use level filters to show only relevant disciplines. Create level libraries (.dgnlib) for consistent standards across files. Apply 'ByLevel' symbology so elements inherit level display properties for uniform plotting.
