Capabilities
What Version Comparison can do
Load Two IFC Versions
Open an "old" and a "new" version of the same IFC — for example, from two different project phases or after a design revision.
Instant Comparison
The comparison runs automatically the moment both files are loaded. No manual configuration — Radalt Toolkit handles all element matching and comparison logic internally.
Added / Deleted / Changed
Results are organized into three clear categories: elements that were added in the new version, elements that were deleted, and elements whose properties changed.
Color-coded 3D Visualization
Added elements appear in green, deleted in red, and modified in blue — directly in the 3D viewer. Toggle each category on or off to focus your review.
Property Change Details
Click any changed element to see a side-by-side breakdown of old vs. new property values — pinpointing exactly what was modified.
Export to BCF or PDF
Share the comparison results with your team by exporting to BCF (with viewpoints) or as a formatted PDF report with change lists and 3D screenshots.
