I am designing a radius Sanding block for guitar repair on Rhino 7, then I export it as .STL file. When I import it to Easel the radius disappears, but the cone I have drawn next to it works perfectly.
The sanding block I designed, the cone drawing is made with a tool in Rhino, both are “closed solid polysurfaces” What am I doing wrong?
Can you share the STL here?

Do note that your Material thickness setting in easel is far thinner than your design. I doubt this is causing the issue your concerned about though.
I suggest opening the stl in other programs to verify whether the concave radius is even part of the stl file or not. I have to presume the curve isn’t actually part of the stl until verified. Which is likely why Neil would like to see the stl 
I use Rhino 5. Maybe check the geometry box and uncheck the textures. I also use Meshcam to create my Gcode. Works great!

Yes, someone mentioned Meshcam to me before, I might give it a shot.
Hi Neil, Yes I can, Sorry I hadn’t responded before, I was moving my shop from my house to the new place. Anyway here it is.

This looks like an issue with the STL. It does not have the same geometry as it appears in the image of your 3D model. I don’t know Rhino, but this looks like a settings issue on the export.
Here’s an example I just made in Fusion of a similar shape. How does this import?

Hi Neil, yes, yours imports correctly intro easel, now can you share the export settings you use?
Thank you for going way beyond your way to help me. I appreciate it.
Again, I don’t have experience with rhino.
Is the screenshot you posted above the only STL export options? If so, I’d try @MartinW.Mcclary suggestion above.
What do you typically use Rhino for?
This is what I get in your file
…no radius
and in meshcam…same thing
Somewhere along the lines you have a setting that is wrong… I’d ask in a Rhino forum.

Ok my good men, finally found the answer on a Highline Guitars Video with Chris.
I had the wrong settings. First you Export Selected, as STL File, then:
Save Geometry Only
Tolerance 0.0001
STL Export options just Binary
And Victory!!
THANK YOU Everyone involved.
