When having large complex models with 20 000+ objects such as pipes. Marking objects to edit Assets is complicated. Marking the 1000+ something objects one by one is not an option. When using the sectioning tool it only alter what object you view but not the ones you mark in the view. Resulting in having a section box or planes active and thinking you only mark the objects viewable but in reality marking all objekts outside of the sectioning box/plane as well.
This creates a huge problem when marking assets in large complex models with tiny objects. Instead the sectioning tool should work like a filter - if you have sectioned off objects they should not be possible to mark (!!) - making the workflow for updateing assets in specific areas in a large model more secure and effective.
