Emblem Issue

[Niray]

Hi folks!

I'm doing some Rhino exercises in free time (it's rather quite rarely), which is much more appropriate for some things than poly-modeling software. I figured out pretty much stuff (yet not enough to model a car), but I simply can't say what's the problem here;

It's a Peugeot emblem, which cannot be filleted =)
I tried many techniques in creating surface, but "fillet" result is always the same. Splitting surfaces with pipe and blending doesn't work either.



Can a pro say what's the issue?

Thanks!

Hi Niray!
Fine to see you are trying Rhino!
Yes, Rhino has some probs with the filet-command...
Try this: check the polyline you want to extrude (press F10 to view knots).Check the connections between the curves. Sometimes the joining of lines makes some problems and open line-ends causes wrong faces.
Or try this: scale your emblem x10 and try to filet or blend surface. Or redefine the tolerance-settings (see your drawing-settings)

Thanks for reply!

I tried what you suggested, as well as many other ways to create surface and fillet, but, always the same, as I didn't change anything. Just one note: After filleting, I get fillet surface separate from the model. Any ideas?

Thanks again for help!

OK Niray, I try it myselfe .
I think it´s the way you create the polyline. There are some tricky edges in this shilouette. I use mostly simple line-parts and join them. Then I extrude this curve, create a 4-point surface at the bottom , copy it to the top and cut both with the extruded curve , join them. Some edges (see the red arrows) I rounded after joining all faces. Now select all edges to filet by picking them inside-rectangle in topview .If there are still errors, fix them by changing the polyline and start again
If you want to I send you my emblem...

Thanks man!
You see, I created the shape using Control Point Curve, which has lots of point in corners, so fillet would destroy the model.
I think I got it, thanks!

Resume: You created the shape with poly-line? Could you post screenshot with points turned on?

Many thanks!

I don´t use only polylines... there are simple arcs and curves too. I try and change parts if there were errors. Important is, to use the same or a bigger radius then the fillet-radius!

good luck!
