MicroStation V8i Select Series 3: The Definitive Guide to Bentley’s Legacy Powerhouse

Plotting & Printing

• Pen tables (*.tbl): Extremely powerful but arcane. You can map any color, weight, or level to a specific printer pen width, screening, or even skip elements.
• Print organizer: Batch plotting works reliably. Supports multiple printers and page sizes in one job.
• Print to PDF: Native output using Bentley’s PDF driver (better than Microsoft Print to PDF). Supports layers in PDF.

8. Sample Workflow: Creating a Simple 3D Building Mass

To illustrate the practical use of SS3, here is a typical task sequence:

1. Start a new 3D file – Seed seed3d.dgn.
2. Set working units – Settings > Design File > Working Units: meters, 1:1.
3. Draw footprint – Place SmartLine: 0,0 to 10,0 to 10,15 to 0,15 to C (close).
4. Extrude – Solids > Extrude: select shape, distance = 20 meters.
5. Create windows – Draw a rectangle on a wall face, then use Solid > Subtract.
6. Assign levels – Level = “Exterior Wall”, color=blue, weight=2.
7. Attach reference – File > Reference > Attach: site.dgn.
8. Generate 2D sheets – Create a drawing model, then place drawing boundary on a sheet model.
9. Print to PDF – File > Print > PDF driver, level overrides = on.

Troubleshooting & performance tips

• Fix display glitches: View > Regenerate or use "fit view" and purge unused levels/elements.
• Performance: Turn off unnecessary levels/references, enable hardware acceleration, and increase memory for large models.
• Corruption: Use Audit and Recover tools; copy contents to a new seed file if persistent errors occur.
• Backup: Keep incremental backups and use version control for important projects.

5. Cleanup Your Workspace

Over time, DGN files can become bloated with unused levels, empty text nodes, and orphaned elements.

• Use the "Compress Design" utility (File > Compress Design) regularly. It reduces file size and speeds up open/save times.
• Run "Delete Unused Levels" to keep your level library clean.

3.4. Parametric 3D Solids

While not as advanced as MicroStation’s current parametric capabilities, SS3 included robust solid modeling tools: extrusion, sweeping, lofting, and boolean operations (union, subtract, intersect). It was fully compatible with Parasolid kernel (same as SolidWorks and NX).

MicroStation V8i (Select Series 3) — Complete Review

Summary

• MicroStation V8i (Select Series 3, often abbreviated V8i SS3) is a mature CAD platform from Bentley Systems focused on 2D drafting and 3D modeling for infrastructure and engineering workflows. It emphasizes stability, interoperability with Bentley’s ecosystem, and support for large, complex datasets (including raster, point clouds, GIS, and engineering models).

Key strengths

• Stability and performance: Proven for large files and heavy, multi-disciplinary projects; robust memory and file-handling compared with many legacy CAD tools.
• Interoperability: Excellent support for industry formats—DGN native, strong DWG import/export fidelity, good support for IFC, SHP, and common engineering formats; integrates with Bentley ProjectWise and other Bentley products.
• 3D capabilities: Solid modeling, surface and mesh tools, 3D visualization, sectioning, and solid editing suitable for civil, structural, and plant engineering tasks.
• Precision and drafting control: High-precision coordinate handling, advanced snap/accuDraw tools, customizable working units and coordinate systems.
• Raster and imagery handling: Built-in raster manager and georeferencing make it practical for overlaying surveys, orthoimagery and scanned plans.
• Customization and automation: VBA, MDL, .NET and key-in scripting allow significant automation and plugin development.
• Enterprise features: Works well in enterprise workflows with versioning, references, and XFM (extended file metadata) support.

Notable limitations

• Aging UI/UX: Interface and workflows feel dated compared with modern, ribbon-centric CAD platforms; steeper learning curve for new users.
• Licensing model and costs: Historically enterprise-focused licensing can be expensive for small teams or solo users.
• Incremental innovation: Select Series 3 is an incremental update in a long product lineage; some modern cloud/mobile-native features are limited compared with newer Bentley releases.
• 3rd-party ecosystem: While broad, some modern plugins and community tools are less abundant than for other major CAD platforms (e.g., AutoCAD).
• Learning curve: Powerful but complex — requires training to use features like AccuDraw, References, and Levels efficiently.

Core features and how they perform

• DGN native format: Optimized for large engineering datasets; handles references and levels reliably; good compatibility across Bentley tools.
• DWG/DXF interoperability: Strong import/export fidelity; some complex entities or custom object types may need adjustment after conversion.
• Modeling & Visualization: Solid/surface modeling, mesh tools, and visualization produce high-quality deliverables; rendering quality is adequate but not focused on photorealism compared to dedicated renderers.
• Annotation & documentation: Robust dimensioning, text styles, and sheet composition tools; sophisticated plotting and batch print via Print Organizer.
• References (XREF-like): Very capable reference management with clipping, levels, and attachment options; excellent for multi-discipline projects.
• AccuDraw & AccuSnap: Very powerful precision drafting aids once learned—speeds geometry entry and alignment.
• Point cloud support: Handles large point clouds for as-built modeling and survey integration.
• GIS/geospatial tools: Georeferencing, coordinate systems, and integration with spatial datasets are solid for infrastructure projects.
• Customization: MDL and .NET add-ins enable deep customization; VBA remains available for simpler automation.

Performance and stability

• Generally stable and optimized for heavy engineering use; handles multi-gigabyte drawings and multiple references better than many CAD programs of similar vintage.
• Startup and some operations can feel sluggish on older hardware; performs best on well-resourced workstations (fast CPU, plenty of RAM, SSDs).

User experience

• Target audience: Infrastructure engineers, surveyors, civil/structural designers, and firms using Bentley ProjectWise or other Bentley enterprise solutions.
• Learning curve: Steep initially but highly productive for experienced users. Training recommended for new adopters.
• UI: Toolbars, menus, and key-ins are powerful but dated; newer Bentley releases have modernized UI more than V8i SS3.

Comparisons (brief)

• vs AutoCAD: More tailored to large infrastructure projects, better native DGN handling and references; AutoCAD has larger 3rd-party ecosystem and more modern UI. DWG interoperability in V8i is good but AutoCAD remains the native DWG authority.
• vs Revit: Revit is BIM-focused for buildings; MicroStation is broader CAD/engineering focused and better for large civil/geospatial datasets; Revit has stronger parametric BIM workflows.
• vs Bentley CONNECT/ newer Bentley releases: Newer Bentley platforms add cloud integration, modern UI and enhanced BIM workflows; V8i SS3 remains a stable, on-premises-focused choice.
