Any decent sized BIM project will have many comments with many attachments using BCF files. It is industry standard to use this format in many parts of the world (including mine) as a common format to report issues.
This is the format our road authority uses to provide feeback and these files are normally 50-100Mb in size. Currently, Issue Resolution only supports import of BCF files up to 30Mb in size. This is insufficient in real world project delivery. Increasing this to a very large size (or even unlimited) is critical to allowing users to make the most of Issue Resolution and be able to use this platform in real world BOIM projects
