How to draw lines on 3d geometries?

I have an IfcProduct with Representation.Representations[1].Items containing its only 3d geometry, which is a cylinder. I’d like to draw some lines representing the borders of metal sheets on the cylinder, using entities included in CoordinationView.
What is the standard way of doing so?
I was thinking of using IfcProductDefinitionShape.HasShapeAspects[1].ShapeRepresentations[1].Items to store the lines.
