When selected, the BCF Manager will instruct your BIM application to create the viewpoint only using the provided camera position and clipping planes, greatly decreasing the rendering time.
Issues and Clashes are often found between components in different models. For instance a pipe in a MEP model may go through a wall found in the structural model. Although most BIM applications will allow you to visualize the federated model, the BCF Manager can sometimes, such as in Revit, only access those components which reside in the native model. The result is that after zooming to an issue, only the components in the native model can be seen.
In these cases you can use the Section Box feature. This will instruct BIMcollab to automatically place a section box around the affected components, providing a much better view of the issue allowing you to quickly get to the root of the problem.
