face selection issues

[tushar_v]

Software automatically stops selecting surfaces through face selection. this is happening quite frequently . even after changing the face selection options in preferences there is no change. seems like software does not want top respond to preferences. only selection through surface edge works.

the only workaround is to restart alias and hope it doesn't happen again.{which it does. 😞 }

Is anyone else having this issue too? hoping to get a solution as it gets quite annoying after a while.i am using latest version of alias. Please help!

Hi Tushar,
Sorry to hear you are seeing issues in such a critical area as selection! So let's work on getting this fixed. Are you saying it works in the beginning, but stops working after some time? Or does it simply not work ever?
Saying you are on the latest version, this means Alias 2021.1?
I did a quick test on a very simple example in 2021.1, and it seems to work fine for me.
I assume this is a new issue now? If yes, what was the last working version (if you know)?
Thanks,
GG

Hi Michael,

Yes, the version is 2021.1. The problem is not there from the beginning but starts after working on a scene for a while.

And also it does not happen every time but is very unpredictable. It has happened to me about (say) four times but its quite annoying when it happens. I have never had such issues in previous versions. also with recent update crashes after tumbling or rotating a scene has increased. Could be some error(preferences maybe) on my system (fingers crossed), if there is anything from my end that could help, like settings tweak or preferences dump then please do let me know.

Thank you for you time and reply,

Regards,

Tushar

Hi Tushar,

Okay, this will be a bit tricky, as it does not occur straight away. While I will ask my QA people to test this, can you please provide some more details on this:

Which version of Alias did you use before, which did not have the problem? 2021.0?
Once you see the issue, does the shading mode matter (wireframe, other diagnostic shader, hardware shade)?

On your crashes, do you send out CER reports? If so, do you have a number for me, or did you provide an email address I could check on to find it?

Thanks,
GG

Hi Michael,
The issue happens regardless of the shader( wire shade / hardware shader).
The previous versions were 2021 and before that 2019 versions. I have sent
reports under tushar_v@nid.edu email id.

Okay, I see your crashes. I created ALS-11556 to investigate those.

On your face selection issue, just to be 100% precise: you do have "Preferences - Selection Options - Face Selection" switched on, it works in the beginning, but then stops after some time. Correct?

[tushar_v]

Yes, that is correct.

But now after further working with the same file and having many iterations
saved i haven't come across this issue.

I had reimported my user preferences after saving few iterations. Not
certain if this is a permanent fix.

[Michael-GG]

Okay, please let me know in case it should occur again. Thanks!

Hi Tusher (and Autodesk),

Yep, I have this problem on an irregular basis as well and I'm running 2021.1

Cheers Daniel

[Michael-GG]

Thanks for letting us know, I asked my QA people to explicitly look out / test for this. Will let you know once we know more.

[Michael-GG]

Can you please let me know which option you have active in the selection options, and is therefore not working, "Closest" or "Pick Through"?

[bob55]

Is the face selection problem occurring with nurbs geometry, or Subds or reference data?

[Michael-GG]

@tushar_v a developer had a look into your crash reports, and Alias crashes in your graphics driver. Could you please try upgrading or downgrading your driver to a different version?

[danielcUPK8E]

Hi Bob,

It is occurring with NURBS and my settings are 'Face Selection' and 'Closest'. I'm running a Nvidia Quadro P4000 with driver version 442.5

Hope this helps.

Regards,

Daniel

[Michael-GG]

Thanks, Daniel!

@tushar_v are you also using "Face Selection" on and "Closest"?

Thanks,
GG

[tushar_v]

hi, 

sorry for late reply. yes face selection with closest option. 

[tushar_v]

Hi Michael and bob, @Michael-GG  @bob55 

I have come across this issue again even after the driver update. A video of the issue is attached.

@tushar_v thanks for the attached video.
I think I was able to reproduce the described "issue".
In your video, you are working with folders and pick object.
When you open the option-box (marking-menu > pick object) can try to uncheck filter unpickable layers.

Best regards

Kai-Timo

Hi Kai,

The option is unchecked i can assure you that. Also this issue does not
take place from the begining. During the course of working with a file this
issue pops up. ( Without any triggers or setting changes).

It recurring for the past few days.

Tushar
