I have a bunch of solid models and surfaces that I'm importing into SW2010 from CATIAv5 as an iges. I need to add some features onto the edges of these models. I'm on task with this but when I select the edges of the models and convert them to 3DSketches, a number of gaps come up. When I look closer to repair them, it seems like the model comes to a single point, but the converted sketch does not. This poses a problem because I need a continuous path for many of the other operations. Any thoughts? Please help!
