You did not specify what radius you wanted on the fillet. I made a guess.

 

Did you create the guitar body profile using a series of short line segments?

This is not a complex solid - it is a simple solid that could be simplified a lot more.

Your sides are hundreds of planar faces. You should use tangent continuous curved to model something like this.

Complex to me...:)

 

I used spline to create it and then converted that to a pline.

 

Not sure what you mean by "tangent continuous", but I'll look into that.

 

1/2" radius. How'd you do that Remark?

Why? You should have used the spline. Can you attach file with your original spline here?

I created a edge profile and extruded it around the path represented by your profile. I filled in the remainder of the body by offsetting the path 1/16" and extruding it. Finally, I unioned the two solids.

Tried this by exploding the 3dsolid and got a region, when trying to extrude a quarter-circle along that region I get "Cannot extrude along this path."

I exploded the region and used the PEDIT command to join all 400+ line segments/etc. which resulted in a closed polyline. That's what I used as my path.

I'm back at trying to do this, this time on a different body profile.

 

Started with a spline this time and could get either method to work; extruding a profile along the edge or using the Filletedge 3d command.

 

Using v.2014 now.

Your spline is a mess.

Forget about using splines - use tangent continuous arcs.

 

Running a curvature analysis on your spline in another program shows many rough locations, but one in particular (at location of red arrow) (this one is difficult to see in AutoCAD - zoom way in at red circle in attached).j body_jd.dwg

 

In general when creating a spline you want to use as few points as possible and let the software do the interpolation between points. It is a common misconception that more points = better curve.

 

Also - I recommend that you work with the origin (0,0,0) at the approximate center of area of your geometry (if it were a symmetrical part - I would have the origin dead center).
