Bulk Types Creator

Bulk Types Creator is a pyRevit extension that streamlines the creation of family types for parametric Revit families. Designed for BIM managers and content creators who frequently populate families with dozens or hundreds of type variations, this tool eliminates repetitive manual type creation and reduces human error.

The tool operates exclusively in Family Editor context and leverages the Revit API's FamilyManager to batch-create types from either manual entry or imported text files. With intelligent duplicate detection and per-type error reporting, it ensures data integrity while dramatically accelerating family development workflows.

Key Features

• Manual Input with Enter Key Support: Quick type name entry in a text box—press Enter to add to queue for rapid data entry
• Text File Import: OpenFileDialog for .txt files with UTF-8 encoding via codecs.open for reliable international character support
• Duplicate Detection: Case-insensitive checking against both the queue list and existing FamilyManager.Types to prevent duplicates
• Queue Management: Add/Remove queue with ListBox display and live count ("X types to create")
• Batch Creation: Single-transaction creation using FamilyManager.NewType(type_name)
• Per-Type Error Reporting: Exception details for failed types with result summary (created count and failures)
• Auto-Close on Success: Window automatically closes when all types are created successfully

Technical Implementation

• pyRevit Framework: Built on the pyRevit extension platform
• WPF/XAML UI: WPFWindow-based interface for a professional Windows experience
• Family Editor Context: Validates and operates only when a family document is active
• FamilyManager API: Uses FamilyManager.NewType() for type creation within a single transaction
• UTF-8 File Handling: codecs.open ensures correct encoding for imported type names
• Transaction Management: All type creations executed in one transaction for consistency
