Align_Bottom doesn't work

Hi there. Usually I use align_bottom to make buildings all sit on a same z-axis plane. But it turned out to be not working at this time as below. I have a test file uploaded as well. Does anyone have same issue or know how to fix it? Thanks.

Hello - the CPlane is apparently not what you think it is in that view - I would change the setting to align to the World.


Thanks for replying, @pascal . When I changed the setting to AlignTo=World, seems it is unable to move things horizontally, although I selected bottom. Please see it as below. Thanks.

Hm - yeah, sorry - it’s still only a 2d operation in world XY, so that does not help you - use CPlane and make sure the CPlane is in fact world right. (it does work here)


Thanks, @pascal . I changed the CPlane to World-Right, followed by Align-Bottom in right view but it is still not working as below. Any steps I missed?

Here is what I see-

Can you please run the SystemInfo command in Rhino and copy/paste the results here?


Hello - this is quite a bit behind - please get the latest and see if that works any better…


Got it. Thank you so much for your help and patience, @pascal .
