Changing position of an object

[ypark137]

Hello,

I cannot change the position of an object. If I try changing the z position, it gives an error.

path = ImagingPath()
path.append(Space(d=10))
path.append(Lens(f=5, diameter=3))
path.append(Space(d=3))
path.append(Aperture(diameter=3))
path.append(Space(d=17))
path.display(ObjectRays(5, 0.1, z=2),
removeBlocked=False)

---

AttributeError Traceback (most recent call last)
Cell In[10], line 7
5 path.append(Aperture(diameter=3))
6 path.append(Space(d=17))
----> 7 path.display(ObjectRays(5, 0.1, z=2),
8 removeBlocked=False)

AttributeError: 'RayTraces' object has no attribute 'extend'

Perhaps something changed after this thread from 2020? #230

Thank you!
