I have a cooling container and I want to seperate the inner wall as a seperate body. How can I do this?
What is your intention? could you just model the two seperate shapes and assemble them or does it have to be one solid just not merged? my best bet would be to create your initial trough shape then when you make your intended shell just include the wall thickness in your cut. then make a reference plane in the center of the part. section cut the part and make new sketch on the plane You just created. draw a rectangle collinear to the edges of the cutout we just made. now click extruded boss > choose up to surface on both directions and click the faces intended to fill the cutout with but uncheck the merge result box and click the green check mark. now just make your cut out from the top surface and you will have your 2 bodies.
You can use the Split feature (Insert/Features/Split). Extrude a U-shaped surface that separates your wall from the rest of the part, and use it to split the part into two bodies. Thinking about it, you probably have to make a 5-sided box surface to completely enclose the wall. An alternative is to use a U-shape, which will split off the wall, but also parts of your box in front of and behind the surface, then combine the box parts back together.
