I work for a playground equipment manufacturer and I'm trying to design a slide in Solidworks which would be made from Stainless Steel. I can design a slide which sweeps across 2 dimensions but cannot get the profile of the slide to sweep across 3 dimensions without twisting.
I am using a projected curve to initially get the path of the sweep. I have tried to add guide curves to the sweep to restrict it and prevent this "twisting" but this wont work. I have attached this file so you can take a look.
The slide obviously needs to be angular so that it can be cut into sections then flattened as sheetmetal to give the final cut profile.
I have used this method or similar to made the 2D slides before. In this instance it has been used to made an air conditioning duct; http://www.youtube.com/watch?v=VU8EjtD6Tgk.
Below is an image of a similar slide we have made previously to show what we're after. We didn't use SW to design this one.
I am also looking to design an 8m high spiral slide, but one thing at a time...
If you have any further questions or require anymore information please let me know.
