How to patch / fill this gap?

Dear Community,

I would like to fill this gap to be able to 3D print. (The pipe needs to touch the inner edge of the hole for the smoothest transition possible, so connecting to the outer edge and cut-revolve is not an option)

While I am going to work on the "gap filling", fillets and chamfers like those highlighted should be applied with solid (or surface) modeling features. They should not be part of a sketch.

I sometimes find it more convenient to have one place/ sketch which controls the dimensions. Also sometimes it is crucial since other measures depend on the size of a fillet or a line between two fillets marks the center point i need etc. ...but generally I get your point. Thank you!

Would this work?

I think you could simplify the timeline a bit, but I worked with what's in the timeline so far.

Hi,

Normally the forum recommends a couple of things with sketches. Try to keep them simple and limit them to a few

features, then use the fusion tools to do you modelling. If you are doing something complicated then do it with

several sketches. The reason for this is that if a sketch is too complicated then it is hard to follow. Another reason

is that the way fusion deals with sketches and they way it deals with the modelling tools are quite different.

The best example I can give you is this.

All I did was make a fully constrained rectangle. Then I put a fillet onto a corner and it immediately gives me a

warning. This particular sketch is fully defined but some slightly more complicated ones break and I then have to

go over the whole sketch and fully constrain it again.

If I extrude my original rectangle and then use the fillet tool.

What I will get is exactly the same end result that I was attempting to do by putting the fillet in the sketch but this

time there is no error.

When you are modelling it is the sketches that guide you to create the model from the tools. It is not the final sketch

that you base your engineering drawings, animations, simulations and manufacturing tool paths upon, fusion creates

all this stuff from the final model.

Good workflow says keep the sketches simple and use the tools to model. You will end up with much better and more

accurate models and the follow on operations you use the model for will be more robust.

Cheers

Andrew

Hi! I believe you just need to extend the Loft surface on both ends. Then use the inner face of the cylinder to split the thickened body.

Many thanks!

Thank you very much Andrew for this excursion into proper modelling 🙂
