Coaster Project Stalled - Need Advice

There haven't been any updates on the CATIA Vekoma flying coaster project lately because I have kind of run into a brick wall. The last time I tried to load the project it took twenty-five minutes. The reason is because there are 100 something points all connected by a spline which is then ribbed. Those commands take a big toll and end up making the file size huge. And there are three of those in the coaster model (spine and two rails). I have yet to figure out a way to make those load or compute faster. I tried making them into dumb solids but that barely seemed to help. Any ideas?
