T-Spline surface smoothing

[Anonymous]

I like the sculpting features in Fusion a lot, but anyway after pushing pulling edges and points and surfaces it very often happens that there are ripples, nudges, unexpected folds in the surface, like in the attached image. The fold shown is not on a specific edge or point I could grab and pull out. I have also no clue where it came from. I assume (simply said) I was pulling somewhere and did not notice that I created that fold somewhere else. Here comes my question: Where do I find the tool to "smooth", "Iron" or "sandpaper" this fold. And if it exists, where can I limit the area of such a tool ? I know that with a bunch of clicks here and pulls there I can probably smooth this one. But I am searching for a simple way.

One more tip for a slight enhancement on @PhilProcarioJr screencast. If your object is symmetric across a plane, then instead of mirroring it and welding vertices, you can also select the edge loop down the middle and use the Modify -> Flatten function to flatten it to that to that plane.

But just as with any modeling in Fusion 360, closely observe you model/geometry afterwards and make sure there are not unintended changes you you geometry.

Some observations:

A full page of posts here are off-topic- or, rather, they relate to disabusing rather than education. 

Marking a snarky post as solution was a disservice to readers in general and the original poster specifically: anybody clicking "Solved!  Go to Solution."  found a post of little-if-any utility.

Ya, Fusion often requires an attitude adjustment.   It's like this: Autodesk makes a new sort of hammer, harnesses the community as play-testers and potential customer base.  The  AutoHammer could use a few basic things- maybe a mouth for pulling nails, or a hole in the handle for a lanyard -and the team says, ya those would be great, we'll get to them when able.   AutoHammer has a few flaws, too-  unfinished casting lines marring the striking face, a sprew inexplicably untrimmed and unfinished remaining mid handle.

Some folks who have suffered through the absent features and flaws are intolerant of those who find them inexplicable or exceedingly difficult to work with.    These folks have been padding their gloves and rotating the face just right when striking so as not to mar the surface or wear a hole in their hand.   They sometimes expect you to A) judge those solutions acceptable and B) come to their state of acceptance at a pace convenient to them.    To compound conflict still more, those most capable of addressing user problems/education gaps are often impatient-kum-hostile toward those who haven't arrived at their pragmatic acceptance.   They may also be exceedingly generous with their time and expertise.   ( In these ways, we users have much in common with the tool! )   Fact of the matter is, this T-Spline issue has been confronted many, many times- there are a great many posts on the topic.   So... I sympathize with the frustration of those offering help while simultaneously lamenting the tact taken.

I reckon this thread points to a real threat and need.     "Elite Experts" (a bit aggrandizing, no?) are essential ambassadors for this tool.   It's should come as no surprise they tire of doing the same educational work over and over.    While a forum such as this has obvious utility, limitations are plain, too.  Me thinks compendium articles addressing these common questions/challenges would be of service to both Common Neophytes and Elite Experts.   Who knows?  Maybe en-mass they might comprise a sort of... what's that word? -oh, ya: a manual.

I am not sure if you refer to me. I am not getting tired of repeating the same thing.

Yes new users could sometimes make use of the search function - but that even happens to me.

However I like the idea of a "how to do stuff" in the form of a community driven wiki system.

And what would that threat be ?

Expert burn-out/disengagement/short tempered or exceedingly brief address of queries.

If you only read the answer that was marked as a solution then I can see that you come to this conclusion.

Were one to expand consideration beyond that one post, free investment in a particular perspective, a number of other examples- here and in other threads -are readily available.   No personal rebuked was intended; rather, I bore withness to a general condition.

I did not understand your reply as such. I am also not dismissing that Expert Elite burnout might exist and I appreciate the concern. But I can assure you that for at least 2 of the other Expert Elites that participated in this thread that is not the case.

I know Phil and Claas personally and talk to Phil  almost daily. I can assure you, there's no EE burnout. 

As it pertains to Claas and myself there is also definitely a cultural aspect to this. Claas and I met at AU in 2016 and discovered that both of us grew up in the same area in Germany. In the area we grew up in people are up front, frank and often brutally honest.

The problem is that there is a lack of good tutorials on Autodesk to learn the right way to work with T-splines.
The reciprocating saw tutorial, the only one that exists, is not great, it is incomplete, too complex to understand this concept.
Then there is the bike helmet, far too quickly explained, and then, nothing else...
