ORD Tilted plan

Hi,

In MX you could create a tilted plan from 3 points (x,y,z) by Transformation- 059 tilted plan.

How can I do something similar in ORD?

I need it to place/create a cell for a roundabout from 3 crossing roads (x,y,z)

Looking something like the below but just a terrain/tilted plan which expands beyond the circle - with the purpose to drape the circle (roundabout)

Regards,
