Compare 3D Models (Model-Based Exchange)

As part of an IFC model-based data exchange workflow, ARCHICAD’s Detect IFC Model Changes tool enables you to:
•
compare two subsequent versions of a structural/mechanical model (IFC files),
•
identify the differences between the two versions (new, deleted and modified elements),
•
insert the changes into the current ARCHICAD model or into an empty ARCHICAD project file,
•
list and manage the changes as ARCHICAD Mark Up Entries.
The controls of the Mark-Up Palette enable you to easily navigate among the changed elements in both 2D and 3D windows and to differentiate and select them, so you can carry out the needed changes in the architectural model.
See Project Mark-Up.
For details on this function, see Change Detection.
Using the BCF collaboration workflow, you can mark the modifications to a given IFC model by assigning comments to the new or modified elements. BCF comments (similar to issues in IFC Detect Model Changes) appear as Mark-Up entries in ARCHICAD.
See Workflows for Using BCF in Project Mark-Up.
