Select Series 3 [hot]: Microstation V8i
MicroStation V8i (SELECTseries 3), released in early 2012, is a 32-bit CAD platform from Bentley Systems designed for infrastructure and building projects. It focused on enhancing 3D interaction, visualization, and interoperability with various file formats. Key Features & Enhancements
Hypermodeling: Introduced the ability to link documentation (drawings, notes) directly within the 3D model context.
Point Cloud Engine: Integrated the Pointools Vortex engine for high-performance display and manipulation of large LIDAR datasets.
Terrain Models: Added a native Terrain Model element type, allowing users to import LandXML surfaces and display contours without needing extra civil software. microstation v8i select series 3
Visualization: New rendering modes like Fast Preview and Progressive Refinement were added, along with a Solar Exposure Calculator.
Interoperability: Expanded support for Autodesk RealDWG 2012, LandXML, IFC, and the JT file format.
Integrated Installer: The installer was redesigned to automatically retrieve and install desktop prerequisites from the web. System Requirements MicroStation V8i (SELECTseries 3) , released in early
The software is a 32-bit application but can utilize Address Windowing Extensions (AWE) on 64-bit systems to swap to extended memory rather than the disk for better performance. MicroStation V8i [FAQ] - Communities
8. Sample Workflow: Creating a Simple 3D Building Mass
To illustrate the practical use of SS3, here is a typical task sequence:
- Start a new 3D file – Seed
seed3d.dgn. - Set working units – Settings > Design File > Working Units: meters, 1:1.
- Draw footprint – Place SmartLine:
0,0to10,0to10,15to0,15toC(close). - Extrude – Solids > Extrude: select shape, distance = 20 meters.
- Create windows – Draw a rectangle on a wall face, then use
Solid > Subtract. - Assign levels – Level = “Exterior Wall”, color=blue, weight=2.
- Attach reference – File > Reference > Attach:
site.dgn. - Generate 2D sheets – Create a drawing model, then place drawing boundary on a sheet model.
- Print to PDF – File > Print > PDF driver, level overrides = on.
Customization & APIs
- MDL (MicroStation Development Language): Native C/C++ API. Very powerful but difficult to learn.
- VBA: Fully supported. Many legacy scripts still run.
- User commands: You can record a macro of actions and replay them.
- No .NET API (at the time) – That came in CONNECT Edition.
Who Should Still Use SS3 in 2025?
Yes, if:
- You are a DOT, railroad, or utility company with a decade of DGN standards.
- You work offline or on legacy hardware (e.g., Windows 7 industrial PCs).
- You need absolute stability over new features.
- Your deliverable is 2D plan sets, not BIM or cloud collaboration.
No, if:
- You need IFC export, point cloud optimization, or reality meshing (SS3 is weak here).
- You collaborate with firms using AutoCAD 2024+ (DWG translation drift exists).
- You want a modern UI, dark theme, or 4K monitor scaling (SS3 looks tiny on high DPI).
- You need cloud-based worksharing (ProjectWise works, but SS3 has no native cloud sync).
2.6. Performance Optimizations
- Opening files with many references was up to 30% faster than earlier V8i versions.
- Pan and zoom in dense 2D drawings were noticeably smoother due to display list caching improvements.
File & Units
- Units: File > Settings > Design File > Working Units. Set master and sub-units and tolerances.
- Scale: Set Annotation Scale (for text/symbols) and Drawing Scale for printable output via Sheet models or scale view attributes.
- Reference scale: Manage view scale with View Attributes or view-specific scale.
Notable Weaknesses & Frustrations
| Issue | Details | |-------|---------| | Steep Learning Curve | Not intuitive for casual users. Even basic tasks (e.g., changing a line color) require understanding “Levels” (layers), “Symbology overrides,” and “Element Attributes.” | | Outdated UI | By 2015, the grey dialog boxes, tiny icons, and modal popups felt ancient compared to AutoCAD’s ribbon or BricsCAD’s modern interface. | | Poor PDF underlay support | Attaching a PDF as a reference was slow and often rendered text as garbage. You’d have to convert PDF to raster first. | | No True Sheet Set Manager | While SS3 had “Sheet Models” (multiple layouts inside one DGN), managing 200+ sheets for a bridge plan set was painful compared to AutoCAD’s Sheet Set Manager. | | 3D Parametrics are Clunky | Trying to use SS3 as a mechanical CAD tool (instead of Civil/Plant) leads to frustration. Feature tree editing is non-existent. | | Ribbon was an afterthought | The optional “Ribbon” interface (introduced late in SS3 lifecycle) was slow, buggy, and consumed screen real estate. Most power users disabled it. |
MicroStation V8i Select Series 3: A Comprehensive Technical Overview
6.1. Setting Up a Workspace
In V8i SS3, workspaces are defined by *.upf (user preference) files and *.cfg configuration files. Unlike CONNECT Edition’s project-centric model, SS3 is user-centric. Start a new 3D file – Seed seed3d
Pro tip: Keep your _ustn.cfg file organized. Use %ifdef statements to switch between office and field conditions.
