Fusion 360 | Surface Blending Exercise

[@Fusion360School]

On hindsight, I could have set the continuity option for the 2 fillets between the small extrude and the disc to curvature (G2). Subsequently, I could also have set the lofts to curvature continuous. This should improve the surface quality. Do try this out and let me know.

[@Tonicwine999]

There are brilliant tutorials, no daft fucking ads, no music, no intro, outro, just straight to the point. Clean and honest tuts and still open to input and new ways of thinking. The only thing I'd have wanted to see was more info on how to do the G1, G1, G2 variable tangent stuff... I have never seen that or understood it in F360 before, didn't like that jumpcut too much.

[@Fusion360School]

Thank you for the kind words. At the moment, I don't know enough about the different continuity options to really give a good explanation as to when to choose which. The approach here is based on my own experimentation. It is a big topic and I will need to continue to learn the nuances involved. Hopefully, I can make a more informed approach in the future.

[@TrippyLighting]

The strong bulge is created by the tangency condition to the flat top surface. If you don't delete the fillet entirely, but leave a little sliver of it then you can control the direction of the surface tangent to it and in effect control the size of the bulge.

[@Fusion360School]

I went back to try this with a small sliver of the fillet. It does significantly reduce the bulge. Thank you for this suggestion!

[@TrippyLighting]

@@Fusion360School I am wondering what shape you are trying to create. You mention that in order to achieve better transitions you could have used G2 fillets. While that is true, using the patch command will almost always be a compromise in surface quality. I've experimented with this interesting shape but don't see a way of sharing it here. Any suggestions ?

[@Fusion360School]

@@TrippyLighting I was actually doodling around with making a watch bezel. That step down would be one of the features where the pin of the strap latches to. Would you like to create a public share link inside of Fusion and post it here? I would be interested to see what you have in mind.

[@dnmnsmith]

As usual, full of detail and clearly explained. Excellent!

[@yagwaw]

Indeed it is

Your channel is absolutely amazing - you've got interesting tutorials, clear narration, no time-wasting and even subtitles! Instantly subscribed. Keep up the good work!

[@ZPositive]

You always deliver mind expanding approaches. Thanks!

[@stefanguiton]

Great video. You could build two patch halves at the half-way point with a profile curve for better control, but that would be an extra step and wouldnt be as quick as your current approach.

[@Fusion360School]

Mmm....will need to try that out. Thanks for the suggestion.

[@medyk3D]

Exactly I've tried it. Splitted the top and front faces, created sketch and used it as midedge. Than patch one half and mirrored it. It takes longer but it's possible to alter the center transition by altering the sketch.

[@Fusion360School]

@@medyk3D This is definitely one way. I was actually hoping to minimise the patch surface by dividing the six-sided hole into smaller 4-sided regions for loft but could not think of a good way.

[@medyk3D]

@@Fusion360School yeah. I have no better idea. Maybe someone else can think about something simple and smart

[@adammonson]

Thank you for making such awesome quality videos. I've learned so much by watching your videos.

[@luisownerbr]

Great approach.

[@asztapaszta9]

Excellent and helpful video, thank you!

[@WPGinfo]

Thank you! I''ve learned many new things!

[@medtuning]

Great one!!!!

[@capnthepeafarmer]

I think I wouldn't have added the fillets to begin with. I would have used the original extrude faces to split the circular body, then blend the primitive shapes. After all the patching was complete, I would have then added the fillets. It would definitely look different, but my approach is to always use primitive geometry before applying fillets.

[@101rotarypower]

Possible you can do a tutorial series how to best set up and effectively use the 3DCONNEXION Space mouse pro or equivalent? Keep trying to use it and not getting the hang of it or realizing benefits, I think a good tutorial on how to use it effectively and why it helps in a CAD environment would be Very helpful! Has anyone seen a good tutorial series on the space mouse, and how to effectively set it up correctly and how to use it efficiently?

[@Fusion360School]

To be honest, I did not put in too much effort into setting it up. I simply plugged in and ignored setting up the hot keys😅. For me, the main reason for using it is for the smooth rotation, which I think provides for a better viewing experience. I find myself using it only when I am recording these videos and not when I am doing my own designs. So I might not be the best spokesperson for this mouse!

[@101rotarypower]

@@Fusion360School I can see its benefits, and many advocate for its use, yet I cant seem to integrate it into my workflow as anything more than a novelty that takes extra time to utilize. I wish the 3D pan feature could be integrated into a standard mouse somehow.

[@Fusion360School]

@@101rotarypower For me the main benefit is that you can decouple the rotating of the model from the mouse clicks. Other than that, I can't really think of a good reason to recommend people to buy what is a relatively expensive product.

[@uriypilipenko1119]

Perfect!

[@paramedic4176]

Tbh, I probably would have just extruded that edge to the very top, instead of halfway, and then just revolve cut a downward angle into it, which can also include the fillet for the top circular edge.

[@Fusion360School]

Yes, you are absolutely right. A revolve would be faster and produce a better surface. During the formulating of this video, this did come across my mind. I had actually intended for this video to be a conceptual exercise on how to break surfaces down and rebuild them to merge with surrounding faces. The model used here might not have been the best example.

[@paramedic4176]

@@Fusion360School That's fair enough. I wouldn't have known how to patch something like that before this video.

[@EugenePentland]

Wouldn't it be easier to just do a revolve that has a profile of that feature, then sketch on the top surface and cut the rest of the body so that feature is only in that one section?

[@smorris12]

I didn't even realise that the items in the profile/edge part of the fillet/loft dialogs were drop-downs! D'oh!

[@RunTheTape]

is it just my vision or your resulting body is not perfectly symmetrical ?

[@marc_frank]

the starting sketch for the tab is not symmetrical

[@RunTheTape]

@@marc_frank ah, Thank you! Thought my eyes are playing tricks.

[@Fusion360School]

Yes, it is not symmetrical.

[@ssattanen]

Didint really get your problem. What was too big? The profile follows perfectly the top of the disk and curves down to the notch (if you mean that on 06:37).

[@Fusion360School]

As a general rule, the patch command should be used as a last resort as it difficult to achieve a good surface with it. If we have no choice but to use it, we should try to minimise the area involved. The surface produced here looks kind of decent in the graphics area. But it probably would not withstand the scrutiny of a zebra analysis. In this case, I have used the patch surface over quite a large area. I am looking for opinions on how I can break this surface down into smaller areas which can be achieved via lofts. Lofts can produce a better surface.
