trouble with creases in my swept surfaces

I'm making progress on my project but I've hit a snag. I have these surfaces weaving about the other surfaces and I can't get them smooth. I've tried pipes, lofts and sweeps, still, they kink. I know it should be simple, but, I'm stumped. Any help is appreciated.

Any comments or changes to other parts is welcome, I'm new at this and trying to learn all I can.

There are two kinds of 'kinks' that I'm seeing. One is caused by the GH render mesh and can be 'improved' by adding a mesh component to the final display result and then turning off the preview of the input brep component. The other 'kink' seems to be caused by too large a radius on the lofted section curves of the vertically oriented tubes. If you're talking about something else I'm not seeing it.

Here's the file.

Actually I'll have to upload it later as the either the GH server or my connection is baulking on the upload.

thank you that works, why?

The render mesh that grasshopper uses is kind of rough. This allows the redraw to update quickly. When you bake geometry into Rhino the baked geometry uses the mesh settings in Rhino not GH and everything will appear smooth. The mesh component in GH incorporates a finer mesh setting than the default GH mesh and is useful if you want to see what your project will look like without actually baking it into Rhino.

that makes sense, thank you. It helps to know why things happen
