Hi Michael,

I will look into the scale thing in the future.

How I constructed the top part:
-I started from rectangle, made a plane and extruded it to a box.
-then I drew my curve in front view , mirrored them, and trimmed it on the surface of the box.
-then I used the extrude tool to push the side pieces away until they disappeared.
( I started out modeling with sketchup, so the new extrude auto Boolean thing kind of makes sense to me = push/pull tool in sketchup )
- next I copied and orated one of my trim curves to line up with my Right view and adjusted it a bit.
- I trimmed this adjusted curve on the solid
- did another push extrude until the part disappeared and had my solid as. It is.

Since had some problems with the fillet tool.
I checked some things out and noticed that the front two curves of my solid was made out of multiple pieces and had to be selected separately ( I think because of pushing the trimmed surface in 2 directions?)
So I joined them, giving me a new curve.
I deleted the front plane, deleted the original (broken) curves and replaced them with the new ones.
At first I did a network on the top front to reconstruct that curved surface, but that didn't help the fillet.
So I went back and did a loft instead.
If I recall correctly, I think I lofted all 3 curved surfaces like that.
At least 2.

I can't send you a file right now,
But I should have a file with the original curves in it, so i can send it to you tomorrow when I'm back at my office.

Hello Glenn,

It just so happens that you're able to get those last two bottom fillets to be a value of 1 and have it end up a nice watertight solid. The key is to extend the bottommost box along the long axis so you can Fillet the lines you indicated with a value of 1. Then just create the bottom box again and select a Fillet operation of 1 on the lines you indicated. Remove the internally created faces and Join the two surfaces together into a Solid. Those fillets along the top edge between the two major parts of your model will probably require a bit more thinking to blend in nicely.
