Steel Fireproofing

Has anyone had any luck with applying fireproofing to a Teckla model? I imported an IFC and all the main members came in as columns. I created something that worked but then got the following error when applying to the IFC.

Warning: Element.get_Faces operation failed.
trim_with_edge_loops requires all curves to touch surface

could you provide some screen shots of what you have done? it will be helpful to those that can help to see what you have instead of just posting a error.
