Edit multipatch geometry with ArcPy

I am trying to use the Buffer3d_3d from arcpy on a set of polylist in lat lon space.

Currently I have been converting the lat lon to UTM and running Bufer3d_3d on the utm data, which works nicely. We have a need to keep the data in latlon instead of converting to UTM. I don't see a way to convert the UTM multipatch back to latlon.

I was trying to use the UpdateCursor function to change the shape coordinates but I get an error:

TypeError: cannot alter multipart geometry type

I also tried to calculate the buffer diameter based on the lat lon distance which ends up being so small that the buffer 3d doesn't output any data.

Any assistance would be great.

Thanks,

Paul
