The issue of empty molecule still exists in avogadro 1.99v

Steps to recreate the issue

  1. Go to build menu option (Keep your layout empty)
  2. Click on any of the 3 options (Add centroid or Add Center of Mass or Add Perpendicular)

App will crash !

@Kiran_Vasave To pick any of the three options (Add centroid, or Add Center of Mass, or Add Perpendicular) becomes chemically useful as soon as there are multiple atoms these can refer to. While repeating your sequence of instructions, I don’t share the observation that the AppImage (version 1.99 for Linux, nightly built fetched on February 13th) crashes, though.

I mean the app crashes when you dont have any atoms in the layout ,it works when you have atoms. You Can clearly see the picture there are no atoms .
