PLY export and axes

General Discussion
1

Hi,

I run Avogadro 1.100.0 on a Debian system.

When I try to export a molecule using PLY export, I get axes included as parts of the exported model.

How do I do to disable them?

Best regards,
Mikael

I would think if you turn them off in the View ⇒ Reference Axes menu item. In general the export options are designed to export exactly what you see on the screen.

I tried that, but it made no difference.

Just to confirm - is the export to PLY including the axes, but they’re not on the screen?

Well, the export to PLY includes axes—cylinders with cones on top, centered on the molecule. These axes are not on screen. However, there are x,y,z-axes on the screen, regardless of whether I have the View->Reference Axes checked or not.

That sounds like two bugs (possibly related) - certainly the axes on the screen should disappear when it’s not checked. I suspect those are what end up in your PLY as well.

@mdjurfeldt Because one can select the molecule (Ctrl + A) and move it on the canvas (after Ctrl + 6, or toggle on the hand symbol), including somewhat closer to the optional reference axes: does the accidental superposition still occur after the selection of the molecule, and view → center?
Does the superposition equally occur for the export to wrl/vrml (mentioned here and here)?

For a few small molecules (lutidine, diethylether, etc.), running the Linux appimage 1.100.0 from a thumb drive in Debian 13/trixie, I didn’t observe the problem your report. However, was your structure a much larger one (possibly a protein read by import from PDB)?
