Bug in "Manage Lost Projections"

[matt.gstaff]

The interface for Manage Lost Projections has some issues. 
This happens occasionally:
I edited some features upstream, removing a face that was projected in a sketch. Of course this created an error, but when I use Manage Lost Projections to delete the geometry, it fails. Pressing the button or using the "delete all" option, break link, etc. does not work and the red outline and sketch error persists. 
There is no other way to delete this phantom geometry. I must simply accept the warning for the sketch or completely remake the sketch and repair inevitable downstream errors. 

Secondly, I'd like to mention that the Manage Lost Projections interface should allow "re-re-linking" of successfully (but improperly) re-linked geometry. Simply don't grey out the "re-link" button after I successfully re-link geometry. in the current state, if I re-link to the wrong line/face/etc., I have to close out of the interface and reopen it, losing whatever progress I had made. 

Thanks

So you feel your tone was appropriate if I had been an Autodesk Employee?

Imagine you are an employee, perhaps an intern who is assigned to help customers on a forum, would you enjoy interfacing with users that exhibit your behavior?

You said (bold added)

Sketch 2 is not broken,

Yellow Icon says otherwise

just the link is lost and can be assigned again, removed or the projected object can be deleted.

No the sketch plane is missing, and has nothing to do with Managing lost Projections.

This is not a user error but inevitable action when you refactor or modify a project. Yes, I deleted the extrusion

User interference, and if you didn't do this, there is no error

but this can happen even when you edit some parameter value and this problem can not be solved without an option to repair or delete a link. I solved this by selecting "delete projected object" but the warning is still here but the problem is solved with dialog made for this situation. Fusion 360 still thinks there is a problem even when the problem does not exist.  Apparently, this problem can't be solved 

by fiddling with Lost Projections.

[vojnar]

This is not appropriate to discuss my inappropriate angry behavior here.

(Paragraph of whinning follows.)

Maybe I am agitated because I must work with Fusion 360 with a lot of old bugs. After all, there is no other similar software I can use and I spent a lot of my time and money on my projects made with it. I really like it, but I really hate how it is managed and developed last few years. It have more bugs than ever, it crashes sometimes, or It is incredibly slow, or delete many unspecified features from my project with my single action without a single word. Here on the forum, everyone needs Screencast, no one wants to believe, no one wants to even test it without inevitable proof or if their opinion is different. Many bugs I must fight happen in complex projects I can't share. So I must live with them. I am not sorry for my behavior because of this weird style of reporting bugs. There should be some bug-tracking website with detailed forms for this and not a forum.. even Minecraft has one.

Yes, I am frustrated and we can discuss my behavior privately If you want.

re-watch the screen cast.  nothing to do with sketch plane.  the projection that is lost is a line from a face crossing the sketch plane.  not talking about a face the sketch was created on, it was created on an origin plane.

I 100% agree with that!

In my screencast, I didn't delete the sketch plane. I deleted extrusion with face projected to Sketch 2. Sketch 2 had a broken link and I resolved it with the Manage Lost Projections dialog but the warning is still present even when I resolved that problem. The warning can't be removed with the Manage Lost Projections dialog.

[davebYYPCU]

At the time the file is opened, there is a yellow sketch icon.  There maybe errors to do with Projections in the sketch, but when you delete an extrusion the sketch is attached to, how on earth can Manage Projections fix the missing sketch plane?

[jeff_strater]

I'm basing this on the screencast that @vojnar shared.  Yes, @TrippyLighting is correct, this is not a bug.

The "Manage Lost Projections" commands does only what its name implies.  It allows you to manage projections whose source are lost.  Projections are entities which are projected into a sketch.  These can either be explicitly projected geometries (created with the Project or Intersect command), or implicitly projected geometries (with either the "Auto project edges on reference", or the "Auto project geometry on active sketch plane") preferences:

However, this command does NOT deal with the sketch plane itself.  If the sketch plane is lost, use the Redefine Sketch Plane command to pick a new plane.

[vojnar]

(just clarifying... not only for you Jeff)

In my screencast, there are sketches defined only on existing planes (on these XY, XZ, YZ). No sketch is defined on the extruded object. (I have auto-projections disabled and that single projection is projected explicitly and then resolved with the Manage Lost Projections dialog.)

When I resolved missing projected objects by deleting projections in the dialog there is no source of warning in sketch2 anymore. Sketch2 is totally empty. I think that warning is a problem created when Fusion 360 is forced to use cached projection instead of a real one (because extrusion is deleted). When I resolved the problem, the cached projection is still cached and considered somehow (even when I deleted the projections) so the warning is still there too.

I agree that "missing sketch plane" is not part of this bug and it is, I hope, overseen mistake that the original author didn't want to make. So please ignore it at focus on my screencast where the only warning is the warning we discuss.

I hope you are not reading carefully because the warning that can't be resolved with a dialog created to resolve it is IMO apparently a bug.

@jeff_strater the original issue that I posted IS a bug

There is inconsistent behavior between projected edges and projected faces. If you lose a projected EDGE, then all is fine, "Manage Lost Projections" can fix it (ie remove the projected edge, and the warning goes away). If, however, you lose a projected FACE, then "Manage Lost Projections" cannot fix it. It gives you the option to fix it, and when you do use the GUI option to fix it, it reports that it has fixed it, but it hasn't

Here is a screencast demonstrating more clearly the issue:

@vojnar couldn't agree more with your rant.

Here is a screenshot of my tickets:

@jeff_strater 

4 Issues in state "Closed - Change Requested", which is AutoDesk admitting that it is a bug, and that support have washed their hands of it. Support will no longer entertain any requests for updates on the status of these bugs,  they say that it is now with the development team and they will fix it at their leisure.

ALL of these bugs are over a year old. and NOTHING is done about them.

As a hobbyist user who doesn't make any profit from F360 (And who only pays so that I don't have to endure that annoying limit on the number of active projects at once), I am FURIOUS that I am paying such an inordinate amount of money to AutoDesk and not getting my issues resolved. I pay more money for my F360 licence than I do to have the parts that I design in F360 manufactured! Hell for what I pay AutoDesk yearly, I could buy a 3D printer AND pay to have the carbon cut for my designs for that year!

[jeff_strater]

Ah, OK, thank you @vojnar - I did, indeed, miss that in the video.  You are correct, there is a bug in that workflow.  It sounds like it has already been reported, so there is no more for me to do here.  Thank you for the clarification.

[Phil.E]

I will admit my imagination is failing me here. Because I can add new geometry and re-associate the yellow sketch with it, which clears up the warning. Is there an example where the user replaces the missing face geometry but the sketch still shows a warning?

[vojnar]

I can confirm that. Reassigning of the projected face or edge work as supposed.

It seems this bug is restricted to projected faces and operation "Delete Geometry" in Manage Lost Projections dialog.

so doing some house cleaning on a model in progress.  look there, ended up not using that body, I'll just delete it and keep things tidy.  oh look, now there's an error in a sketch.  hmm, a lost projection.  no sweat, i'll "manage projections" that sucker, and delete the geometry cause I didn't need it.  thank goodness for that command, don't want to redo the entire sketch, the rest of it works.  weird, sketch still in error state.  break link?  no, didn't work.  i don't actually need the projection anymore (otherwise wouldn't have delete the body), so re-associate doesn't seem like what I want to do.  oh yeah, I vaguely remember this thread where if I unintuitively re-associate the projection i don't need with something else, i'll get a new line.  then I can go and delete the line  and all's good. 

[Phil.E]

Or you could use Remove to remove the body.

and that cleans and tidies up the time line how?

[Phil.E]

For sure this is a bug. I was just hoping to hear why it's so important. Timeline cleanliness is not to be underrated!
