Rounding a part when fillet doesn´t work

Theoforus — Tue, 28 Dec 2021 11:45:22 GMT

Can someone give me a suggestion for how to round the back of this object. I have cutted the back wit a perpendicular profile to get the desired shape, but I would like to have it more round. Any suggestions?

See attached fusion file it that can clarify.

Is it just these edges you want to round?

I was able to fillet them up to 10mm, is that not the result you are looking for? Here is 4mm:

Blending without Fillet is pretty complex. Usually, it requires building a profile and using Sweep. If you help us understand what you are trying to achieve, we may be able to help more. Thanks.

Thanks for taking the time to answer and for your kind reply. I intentionally wanted to round it more, but the best way I could see was to cut it to somewhat the desired shape and use the fillet tool, but I´m not very happy with that. It did not become so nicely rounded as I hoped for. Maybe I could try the sweep command.

Much of this is a surfacing project, including the "rounding". The solid modeling techniques you used only get you so far.

the best way to create a homogeneous external surface is as shown in the film. then cut in half and incorporate your parts. greetings mango

T-Splines might be one way of modeling this object, but stating it is “the best” way is misleading.

I've looked at your model and gone through the timeline a number of times but I have a hard time pinning down what exactly you are going for.

I would design around a general volume that needs to be just large enough to contain all the mechanical pieces, but I would not start by detail designing mechanical interfaces. I would start with the exterior shape first.

In your imagination, you need to break a design down into primary, secondary, and perhaps tertiary shapes and surfaces.

The large surfaces are the primary surfaces. Decorative fillets are secondary surfaces and should be applied late in the design process. your design is a somewhat unorganized mixture and that is the reason why there's no distinct flow recognizable.

Can you create a hand sketch in pencil & paper to show what shape you were trying to achieve?

Thank you so much for taking the time to help me. As you mention I have a lot to learn about structuring my workflow and you are really helping me here. I have tried to make a sketch. See what you can get out of it.

Next time I would probably start with a hand drawn sketch and the t-splint environment. What do you think?

How about the faucet spout. Is that articulating and needs to move or is it a fixed, integral part of the body?

you can still do something, but the question is whether this is what you are looking for?

da kann man noch was tun, doch es geht um die frage ob es das ist was du suchst? greetings mango

In my mind it was fixed. I used the sweep function for that.

That was a nice fix, but as @TrippyLighting states it could have been avoided by better planning and organizing from the start. Thanks.
I will come back to this next time I paint myself stuck in a corner.
