Fusion 360 crashes/stops responding after trying to sweep along a path

[autodesk.comMXBKD]

I'm trying to sweep along a path, ( as described in this tutorial https://www.youtube.com/watch?v=p-raTJt0KPw&list=PLrZ2zKOtC_-DR2ZkMaK3... ) but can't get it to work.

Fusion 360 always becomes unresponsive/freezes for some reason.

The design is here:  https://a360.co/3B1ukBr

Have I done something wrong somewhere unknowingly trying to follow the tutorial causing the crashing (works every time) or am I low on resources? Resources I could accept but shouldn't it quit/exit gracefully then?

And I'm on a 2013 Macbook Pro, with Catalina (10.15.7) running Fusion 2.0.12164 Personal

Error report 318700956

Here is the file, redid the path/sketch with same outcome.

Hi @autodesk.comMXBKD 

Sorry this may not solve your issue, I used the supplied file placed a plane along path at the end of the far black line. Then I made a sketch then a circle on the sketch finished that. Then the sweep command and it worked great! The only issue I can see is if the circle is too large it may become self intersecting. I'm on a 2012 iMac with build 2.0.12164 subscription. I've added my file for reference.

Hi @autodesk.comMXBKD,

Works fine for me.

Edit:

If you can capture the workflow through Screencast/video of what you are doing will help us to reproduce the crash.

I did a screencast of it and when I closed Safari in doing so and it worked like expected.

If I reopen Safari, it's repeatable and still crashes/freezes.

For some reason I cant edit my previous post and clean up the html for the screencasts (took them down now since they don't add anything) but it's a resource issue not related to Safari. Fusion 360 can't gracefully handle not having enough resources and freezes instead.

I can force/repeat the issue opening one or a couple of (random) apps in the background prior to performing the task and it always freezes.

Run Fusion 360 as only application and the task works as expected.

I hope you are still around - I found a very very serious issue in your sketching technique.

First I noticed that your sketches are not fully defined (blue geometry should keep you awake at night).

Then I noticed that you have two arcs where one arc would suffice.

So I tested by dragging the arcs (the most powerful tip in all of parametric design).

I observed hidden zero length degenerate lines at the ends of the arcs.

Q. Why did you use two arcs at each of those locations?  Why did you have lines there?

Edit:  Oh man!  I just watched the video.  That is the WRONG way to create those arcs. @7:35

Now I understand why issues with this Tutorial comes up here so often.

Still here but sadly I don't have any good answers for you.

I'm trying to learn Fusion 360 as a tool so I am looking into tutorials and all of this was done following one of this as stated in my initial post.

I have to refer you to Kevin Kennedy of https://www.youtube.com/channel/UCooViVfi0DaWk_eqxIXXiOQ so he can explain why he did those decisions.

I know why he did it the wrong way.  He didn’t understand the implications of his technique.

Over the years I have seen many examples of this error in logic from users of several different MCAD softwares.
