IFC Merge v3.65

1Open IFC Merge

Launch IFC Merge on your Windows computer. The main window has a file-management panel on the left, a 3D viewer on the right, and output and merge controls below the file list.

2Add IFC files

Drag IFC files into the Drop IFC Files Here area, or select Add IFC and browse to the files. Added files appear in the left-hand list.

3Review the IFC file list

Use the file list to check the source names and units. You can enable or disable a file, toggle its visibility with the eye control, and change the list order. Confirm that the intended files are active before merging.

4Use the 3D viewer

Use the built-in viewer to orbit around the model, zoom into details, inspect framing, and compare how the loaded models sit together. Fit or reset the view if the model is outside the current view.

5Check whether the models overlap correctly

When source files use a shared coordinate system, their geometry should appear in the expected relative positions. Look for unwanted offsets, rotation, or missing geometry before continuing. If placement is wrong, use the placement tools.

6Move a model

Use Move when a model needs to shift. Select the model, activate Move in the placement controls, choose a snap point on the moving model, and then choose the matching point on the reference model.

7Rotate a model

Use Rotate when a model is positioned in the right area but faces the wrong direction. Select the model, activate Rotate, choose a rotation plane if offered, set the reference point, and complete the rotation.

8Align a model

Use Align to match a point or edge on one model to a corresponding reference on another. Select the model to move, start Align, pick the source reference, pick the matching target, and confirm the placement.

9Use section tools

Open the Section controls to inspect inside the model. Depending on the current view and selected mode, the tools can include Pick Face, Horizontal, Vertical X, Vertical Z, Flip, and Off.

Section cuts can help review internal wall, floor, or roof framing and model coordination.

10Pick a face for clipping

Choose Pick Face, move the cursor over the model, and select the face that should define the clipping plane. The viewer creates a section plane from the selected face.

11Measure distances

Activate the Measurement tool, select the first point, and then select the second point. Review the displayed distance as a visual check; confirm important dimensions against your project source data.

12Remove or clear measurements

When measurements are no longer needed, select and delete individual measurements or use the available clear command in the measurement controls. The exact control depends on the active viewer state.

13Inspect IFC object properties

Double-click a member or object in the viewer, then open the Properties panel. Available information can include IFC type, Express ID, GlobalId, name, description, tag, source file, and pick coordinates.

14Save snapshots

Use the snapshot area to keep important review views. Depending on the current selection, controls may include Select All, Clear Selection, Delete, and Share Selected.

15Run Preflight Audit

Select Preflight Audit before export to review merge readiness. Treat it as an additional check, not a substitute for visually inspecting the source and merged models.

16Set the output IFC path

Use the Output IFC field at the bottom of the left panel. Enter a destination file path or choose Browse to select where the merged file should be saved.

17Merge the IFC files

Confirm the intended source files are enabled, check placement and visibility, set the output path, and select MERGE IFC to export the combined model.

18Review the merged result

Open the output in the viewer or your usual IFC software. Confirm expected geometry is present, placement is correct, and the result matches the source models before sharing or using it downstream.
