Allenes: 3D Clean Up

BRIEF DESCRIPTION:
Allenes are not planar, but 3D Clean Up always gives a planar structure.

DISCUSSION:

In Allenes C-H bond framework on the end carbons as well as π-bonds are oriented 900 to each other. However, 3D Clean Up of allenes in ChemDraw always gives a planar structure, even when stereochemistry is intentionally assigned using wedged bonds (Allenes - 3D clean Up.mp4).
