Hi Simone - I do not love, exactly, what I did here, but I think a surface arrangement along these lines may be a good way - I am not sure I am interpreting the photos correctly but, something like this. Ibanez RG570 Genesis JB_Maybe.3dm (341.1 KB)
It’s very close to what i was looking for, i can work with it, but how did you do this?
What comands did you use and what’s your workflow to make this if i mind ask.
Ibanez RG570 Genesis JB.3dm (4.4 MB) Hi , I just worked on the area you were trying to do. I used xnurbs in one section. Isn’t there a command called “sandpaper” to solve these ? you just fill and sand and its all done. — Mark
Hi Simone - the hard part here is finding that simple cut surface - once that is in the right place (not quite where I expected), then making the narrow transition surfaces is relatively straightforward, although ‘fiddly’. In any case, think in general, when making transition surfaces like this, I would start with the object complete but with hard edges, so to speak, then make the transitions in an organized way. It is hard to work from the transition to find the ‘main’ design surface.
Simple cut surface uh? By that you mean like this one for example?
Got your workflow though, starting with hard edges first then filletting and counturing. Got it.
I kinda started like that but i couldn’t get the fillet in the narrow conjunction.
I tried to use the simple fillet comand, tried to cut the interested surfaces, create a profile to sweep with the 2 rail sweep, tried to blend surfaces but it was always glitched in someway. Couldn’t get it smooth…
To be more specific, what comands did you use to get such a smooth and almost flawless transition? (especially in that tricky corner)
Hi Simone - see the attached file - it shows one way to do this with fillets and a single ‘fake’ fillet as a Sweep2 surface. Ibanez RG570 Genesis JBFillets.3dm (897.9 KB)
Hello - no secret - FilletSrf a pair of surfaces at a time, then work out what to do at the junctures, as in my example. Keep in mind that the solution may involve a fillet between an existing fillet and one of the input surfaces. I’d not worry too much about trimming until all of the fillet surfaces are in place.
Sorry for replying so late to the thread but before the quarantine thing i was kind of busy.
I think im doing something wrong…I tried to apply your technique to do these fillets by myself but i really can’t get it right. I get some strange results and by this point i don’t know how to fix it.
The palm indent for the cutaway surface might be made simpler, with fewer nodes that cause fewer control points in the surface, indicated by all the isocurve indicator lines. That surface might be rebuilt. If it can, the result would be smoother, with possibly fewer filleting problems. If a fillet is meant to run across a whole mess of isocurves or segmented splits, it’s a sign that rough sailing might be ahead. If you are using a Boolean object to remove that, perhaps that could be rebuilt and simplified before it is subtracted.
Sometimes it helps to do solid merge all surfaces. I am not sure that its the case, but sometimes not filleting adjoining surfaces at the same time causes problems.
Some other things that will cause filleting problems:
Not filleting edges at the same time, which also might be the issue
Too large a fillet
Inappropriate fillet type
Filleting a surfaces that already have have splits, segments, and split edges–especially if an entire width/length of a surface may be eaten by the fillet
Not filleting the adjoining surfaces
Generally, I keep step-wise versions, in layers, in files, when making deceivingly complicated things. Solid bodied guitars can be tricky to model.
Thanks @Brenda for the advice, surely it’s important that you mentioned how to get a clean surface to make easier some of the later work etc… but i don’t get why i can’t re-create what @pascal did by myself.
He used the file that i made to create the fillets and i don’t get why he was capable to do it and why i’m not, even though i followed exactly what he said using the same identical file project.
I see that some surfaces are not really clean but he managed to pull it off without problem then i try myself and i get all sorts of artifacts and errors. Why? What am i doing wrong? Maybe some settings in Rhino? Even though i never touched those…
Hi Simon - take a look at the cut surface in my file a few posts up and yours here - I made mine flow cleanly to the hard corner of the guitar body:
Blue = Mine
Red=Yours
Green = hard corner of the guitar body.
Notice also that the isocurves on the blue surface are not so stretched/skewed as on the red one - that is done in the Sweep2 command (as I recall) , Add Slash button. Just one is needed to true up the isos to be less at an angle to the sweep edges.
