It is possible to rotate a shape by a fixed value, pending a condition being true.

https://docs.dataminer.services/develop/devguide/Visio/miscellaneous/Basic_conditional_shape_manipulation_actions.html?q=rotate#action-overview

However I have a parameter that is a bearing, Range: 0-359.

I would like to just rotate my shape by the value of that parameter.

I have tried this shape data, so that if Param 68 is >0 it will rotate by the value of that parameter from the Tesla element but no success.

68|Rotate;>0,[param:Tesla,68]

I can get the shape to rotate by fixed values if I do something like this

68|Rotate;>0,135
