Hi Charles and Scott, Thanks for following up. I have created an issue for this bug
hatched turtle in 3D does not have zcor of parent #1822 It appears that the bug only occurs when the hatched turtle is not given commands. That explains why my version did not reproduce the bug. The problem also goes away when optimization is turned off, because optimization runs specialized code in the no commands case.

Aaron, I've done some more testing. First, my system: NetLogo 3D 6.1.1 (September 26, 2019) Extension API version: 6.1 Java HotSpot(TM) 64-Bit Server VM 1.8.0_202 (Oracle Corporation; 1.8.0_202-b08) operating system: Windows 10 10.0 (amd64 processor) Scala version 2.12.8 Java heap: used = 29 MB, free = 348 MB, max = 910 MB JOGL: 2.3.2 OpenGL graphics: Intel(R) HD Graphics 4600 OpenGL version: 4.3.0 - Build 20.19.15.5063 OpenGL vendor: Intel To show you what I see, I've attached a pdf with screen shots of the command center, and the View window, both before and after the 20 second wait has passed. But, your code works, and I think I know why. If you look at the .nlogo3D file attached, I have a version of my code that sets the color of the hatched point. Now, the problem goes away. I haven't tried other modifications to the hatched point to see if they too would solve the problem, but setting the color (or shape? or ?) seems to force the View to put the point at the right z coordinate. I'll look at Steve's model when I get a chance to see if I get the same behavior. Charles ------------------------------- Charles P.

I made models using a version of your code in which the hatcher is a dot, and the hatchee is a larger circle. The dots seem to always be in the circles. I have orbited and zoomed. Could you let me know if you get the bug with these models? If so I will find a Windows machine for testing.
