I'm trying to fillet the edge of a 3d solid guitar body and can't seem to make it happen.

 

Any help, suggestions would be appreciated.

How did you construct the outline of the guitar body in the first place?

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.

The interior "filler". Then all you have to do is union the two solids together.

No, I'm a machine. Next time follow JDM's advice and you'll have a much easier time of it.

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 profile is at fault. As you try to sweep or extrude it around the path it folds back on itself.

I can extrude the guitar body but I can't fillet the edges completely. Odd.

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).
