Element.rotate node rounds off degree values

1

Hi, so I’m using DynaMEP node “Element.Rotate” to rotate a few elements with it’s family origin, my issue is that it rounds off the degree values, is there any other solution?

@rajeshjamariya16

can you share a screenshot ? and the code also. maybe you can skip the rounding.

I used ChatGPT code to get it working.
