In any growing library of Inventor parts and assemblies, file naming and properties quickly get out of hand. Designers often rely on quick, descriptive names tied to dimensions (“tube_100x100”) or duplicate placeholders (“plate_1”), but these break down over time. When parts are reused, resized, or revised, the names no longer match, leading to confusion, duplicate files, and wasted hours tracking down the right version.

This creates several recurring issues:

• Inconsistent file names that no longer match the part or assembly

• Duplicate files across multiple projects

• BOM properties that must be edited manually, item by item

• Time lost searching for the correct version of a part

These problems may seem small at first but compound quickly in collaborative projects. Teams lose confidence in file structures, mistakes slip into production, and revisions take longer than they should. Every round of manual editing eats away at valuable engineering time.

The Numbering Tool solves this by automatically assigning unique IDs (for example, “P-numbers” for parts and “S-numbers” for subassemblies) and pushing property updates across all selected files in a single action. This eliminates the need for tedious manual edits and keeps your entire library structured, consistent, and reliable.
