Thanks for the reply. I understand the differences now in the tessellation when using the slider. I tried the tessellation setting all the way to 1.0 and the file is much larger. Then I tried the nurbs only setting. I didn't know about that nurbs button on the top menu bar. That was the key that I was missing!

Both Beta imports have trade-offs. If I use the regular Beta import and crank the slider over, I get a huge file, but the parts are selectable. In other words, if I select a part, it highlights and I know it's selected.
If I use the Beta import and select nurbs data, the parts do not highlight if I click it most of the time. Other times the selection will highlight. It seems to be from being zoomed in too much. So I have to stay zoomed out.
Also, the hassle of the Beta import is that surfaces that I don't want are imported too. Those surfaces that were used to trim other surfaces. So the selection of those parts if they do not highlight is a real pain if I have to zoom in to select it. Also part names in the Scene parts list are no longer there.
I guess I'll experiment.
I've also noticed that on my 12 core machine at work, KS 5 can bog down and creep when I try to select item in the menus. This was a real surprise as the file worked fine when imported in KS 4. Maybe its a memory issue. If I quit and restart KS 5, it seems okay. A lot of little annoying little things with the good new stuff.
In regards to tessellation and mesh verses nurbs data. I didn't have a very clear understanding of that. I kinda knew always from back to the Hypershot days that models imported are converted to a mesh. And the mesh quality can be controlled either in SolidWorks and or with the slider on the import setting window. With SolidWorks being a nurbs modeller, it would make sense that the nurbs setting would create a perfect model in Keyshot. And it appears to. But with the associated unfortunate unwanted surfaces and lost names in the parts list. Can the Beta importer be improved?
Thanks again for the explanation. It was very helpful. If this is in the user manual, I'll look for it.
