Merge IFC files and preview the result locally

Load and manage source files, inspect and align the models, use section cuts, measurement, member properties, snapshots, and Preflight Audit, then save a merged IFC. The guide covers the core workflow; its reference screenshot is from v3.22, so controls may look different in v3.65. Compatibility depends on your IFC files; review the result before relying on it for project handoff.

  2. Review file units, visibility, and placement in the 3D viewer.
