📥 Clean Imported Line Patterns

Clean Imported Line Patterns performs automatic detection and removal of line patterns imported from DWG files, restoring clean line pattern configurations without affecting native Revit line patterns.
Version 1.2 | Cleaners

Overview​

When importing or linking DWG files into Revit, AutoCAD line patterns are automatically added to the project, often cluttering the line pattern configuration with unnecessary imported patterns. While Revit's standard line pattern management requires individual deletion of each imported pattern, this tool addresses that limitation by automatically identifying and batch-deleting all imported line patterns while preserving your original Revit line pattern configuration.

Key Features​

Usage includes:

  • Automatic Import Detection: Identifies all line patterns imported from DWG files based on naming conventions.
  • Batch Deletion: Remove all imported line patterns simultaneously instead of individual deletion.
  • Configuration Preservation: Maintains original Revit line patterns while removing only imported ones.
  • Link and Import Support: Handles line patterns from both imported and linked DWG files.
  • Clean Results Reporting: Displays count and names of deleted imported line patterns.

Requirements​

Before using Clean Imported Line Patterns, ensure your environment meets the following prerequisites:

 Autodesk Revit: From version 2020 to newest.
 NonicaTab: NonicaTab Pro.

Usage​

Understanding Standard vs. Enhanced Line Pattern Management​

  1. Standard Revit Management:
    • Navigate to Manage → Additional Settings → Line Patterns
    • Review imported patterns manually (typically prefixed with "Import")
    • Delete patterns individually - no multi-selection capability
    • Time-consuming process for projects with multiple DWG imports
    • Risk of accidentally deleting native Revit line patterns
  2. Enhanced Cleanup (This Tool):
    • Automatically identifies all imported line patterns
    • Batch deletion of all imported patterns simultaneously
    • Preserves original Revit line pattern configuration
    • Handles both imported and linked DWG line patterns

Basic Line Pattern Assessment Workflow​

  1. Navigate to NonicaTab Pro → Clean Imported Line Patterns.
  2. Automatic Detection: The tool automatically scans for imported line patterns (typically those with "Import" prefix from DWG sources).

FAQ​

The tool automatically identifies line patterns that were imported from DWG files, typically those with "Import" prefixes or other naming conventions that indicate AutoCAD origin. It distinguishes these from native Revit line patterns to ensure only imported patterns are deleted.

No, the tool specifically targets only imported line patterns from DWG sources. Your original Revit line patterns and any custom patterns created directly in Revit will be preserved. The tool distinguishes between native and imported patterns based on their origin and naming conventions.

Both importing and linking DWG files can bring AutoCAD line patterns into your Revit project. This tool handles line patterns from both scenarios, cleaning up pattern configurations regardless of whether the DWG was imported or linked into the project.

While the tool automatically identifies imported patterns, you can preview your current line pattern configuration by checking Manage → Additional Settings → Line Patterns before running the cleanup. After deletion, the tool displays the names of all deleted patterns for verification.

Use this tool immediately after importing or linking DWG files to prevent accumulation of unnecessary line patterns. It's also useful during periodic project cleanup or before project delivery to ensure a clean line pattern configuration that only includes necessary patterns.

If you need specific AutoCAD line patterns for your project, consider recreating them as custom Revit line patterns instead of keeping imported ones. This provides better control and consistency. Alternatively, document which patterns you need before cleanup and recreate them manually if necessary.
