Hey guy's,

I have a guitar model that has a radius on the back of the heel joint. I'm trying to recreate it but its giving me a hard time.

Let me know if any one has any idea's.

thanks,
Dave

Two thoughts come to mind - one simple but it won't be exact and one more complicated but first let me warn you, I'm just learning advanced techniques in SW.

Simple, make a plane at the same angle as the "chamfer" and do an extrude cut to remove the material. The problem will be that the curves at the transition points won't be there.

The more complicated method would be to draw the curve on the back plane the shape you want and use a split line to project the curve on the vertical plane of the heel. Now loft to cut away what you're looking for.

Part of me is saying that there must be an easier way though. I saw as video the other day of the replace face feature and that very well could be the trick but I don't know enough to adivise on how to use it. Perhaps someone more skilled will chime in.

Figured it out. I'll post a tutorial later. Thanks for sparking an idea.

Please do - now I'm really curious as to how you did it.

First thing that comes to mind is a variable radius fillet.

So all I did was create some sketches with a line at a 20 or 15 degree angle perpendicular to the curve I created on the horizontal flat face. I then connected an 3d sketch arc that is tangent to the two angled lines.



I then lofted a surface and used cut -> with surface and there it is.

I see what you're doing but I don't. Could you post a screenshot of the loft feature? i.e., a screenshot with the loft preview.

[silwandr]

I used a boundary surface sorry. Two guide curves (purple) two open groups (blue)

Ah, that makes much more sense - I couldn't figure out what you were lofting in the previous pics....now I know why
