Importing structural steel components

I am very new to Shapespark, so please forgive any redundancies or “obvious mistakes”. I would like to use this as a showcase and planning software for our prospective clients. We design and build structural steel buildings. I currently utilize Revit for my design software and can not seem to get any of my structural components or connections to import using the Revit add in. I would be happy to offer any more information if someone knows the right questions to ask.

Are the structural components visible in the Revit’s 3D View active at the time you export the model to Shapespark?
