Purpose: Reduce the number of redundant blocks in the DWG

Note: The software scans the entire DWG to find duplicate blocks
Processing mode: DWG files are processed one by one (not all at once).

This tool is used to optimize and lighten the DWG. It detects duplicate blocks (same geometry, same attributes), replaces them with a single unique definition, then deletes the redundant ones. Visually, the drawing remains unchanged, but unnecessary block definitions are removed. This is ideal for standardizing client drawings or preparing a clean project file.

  1. Opening the DWG

    The software opens the DWG file that you want to optimize.

    Opening the DWG before block optimization
    Loading the drawing to be analyzed.
  2. Block analysis and duplicate detection

    The tool analyzes block definitions in the DWG and searches for duplicates:
    blocks with different names but identical geometry and attributes.

    Analysis of block definitions and detection of duplicates
    Identifying equivalent blocks that only clutter the file.
  3. Replacing block insertions

    For each duplicate detected, the software replaces all insertions of the duplicated block with the reference block that is kept.
    The goal: have ONLY ONE block definition for the same visual appearance.

    Replacing insertions with a unique block definition
    Automatic standardization of all insertions.
  4. Removing unnecessary definitions

    The redundant block definitions are then removed from the drawing.
    Visually, nothing changes: the appearance of the plan remains the same,
    you simply have fewer useless block definitions.

    Removing redundant block definitions
    Lighter, cleaner, more consistent DWG.
  5. Saving under a new name

    The optimized DWG is saved under a new name to avoid overwriting the original.
    You can then review the result before final approval.

    Saving the optimized DWG under a new name
    The cleaned plan is saved separately for validation.
