Unable to Use "Rotate around" Correctly

Nyama · May 31, 2025, 4:10pm

Thank you for all your hard work developing Avogadro2. I am a student and have been using this software regularly.

I would like to report what appears to be a bug.
I am running Avogadro2 Nightly Build 1.100.0-7-gac3f38f on Windows 11, and I’ve noticed that when I enter rotation values for the X-axis and Y-axis, only half of the specified value is applied. Additionally, the Z-axis rotation does not seem to work at all.

I would greatly appreciate it if this issue could be addressed in a future update.

Environment Information

Avogadro version: 1.100.0-7-gac3f38f
Operating system and version: Windows 11

Definitely a bug. Thanks for the report.

Not quite sure what’s going on, but I think it’s because some of that code is designed to be used with the mouse rotation and the transforms are a bit different.

I’ll try something later today.

Okay, this looks like it will solve the bug:

Dear Professor Hutchison,

Thank you for your previous assistance.
I would like to report another issue:

As far as I know, on Windows 11, I am unable to select molecules in any Avogadro 2 version from 1.100.0-17-g832ed0d onward. For this reason, I have been using version 1.100.0-7-gac3f38f, which still allows molecule selection. Has this issue already been reported?

Yep. It’s discussed in this thread: Highlight issues in selection tool - #11 by Marti_Sidro

It’s not that the selection doesn’t work. It’s that a rendering change (which I just reverted) made translucent effects like the blue selection indicators invisible.

The next nightly build should have both fixes.

Thank you for your reply. I truly appreciate it.
