I'm started to use hotlink function to link the strucutral IFC model and I set the import settings properly, but the only thing I don't know is that, how can I hide the survey point symbol in the floorplan and how can I pre define the object pen, especially the IFC model element(MechanicalFasteners)with green pen in the picture? I wanted to set this, because I'd like to show the structure in the layouts in a proper way with right pens and linetypes.
I usually convert IFC into PLN and after hotlink it to the main file. It gives freedom to make modifications to the IFC contest and solve similar problems you are describing.
Also, if you are receiving new revision of IFC - you create another PLN and just replace a hotlink.
