What is BCF?
The BCF file format, standing for BIM Collaboration Format, allows communicating issues between different BIM applications.

How to generate BCF files?
In Cyclone 3DR, BCF issues can be generated from specific analyses:
From a set of Inspection Notes (from Inspection Notes BCF or the BIM Inspect workflow)
From a Clash Analysis
Data stored in a BCF file
The content of a BCF issue (or "topic") may depend on the input analysis:
textual information
scene screenshots (called "viewpoint")
additional display data for external viewer ("Visualization information")
attachment files
Interoperability
Cyclone 3DR follows the official standard to write the BCF file. The current supported version is 2.1
However, there is no guarantee that this content is fully supported by other BIM platforms.
Please refer to their respective supports for additional information.

Additionally, the author name is retrieve from the "Author" field defined at the report step.
Viewpoint
A viewpoint is generated for each viewset available in the note.
It stores the camera definition (projection, position, direction) and displays at least:
the inspected model
the inspection labels
Attachment
If labels are attached to the note, a CSV file containing all deviation values is generated and attached to the topic.
Exporting BCF from Clash Analysis
One topic is generated for each selected clash (filtered clash won't be exported).
