Hi guys,

I'm not totally new to solidworks but I never really use many of its advanced features, usually simple sketches and assemblies and I'm hoping you guys can help me out with this one.

What I have is a part from a customer that they modeled in catia, saved in STP and I opened in solidworks and it's all surfaces, no solid modeling that I can see anyways. What I need to do with this part is make a nest for it/remove its profile from a solid block. We had a previous project like this but the customer actually gave me a model of a block with its profile removed and I just built off of that block... this time we do not have that option. From what I could tell it looks like they did some type of surface offset to create a profile and then a surface cut from the solidbody but I cant quite figure it out and feel as though I'm missing a key step or two. If you guys could help me out or point me in the right direction that would be awesome!
