How to rotate the model for 90 deg

[urban.ostirZ44XW]

Hello,

I am totally new to Revit 2023. I am exporting .RVT files from Inventor and putting them together in Revit. I have a problem. All the parts have imported on the right place. But only one element is out of the desired positions. It is aligned in x and y. I just have to rotate it for 90 deg. How can I do that? I am attaching a picture that represents my problem.

What about an Inventor to RFA to RVT workflow?  That is, put the various Inventor components in Revit Families (RFA) and then assemble the different components together in the Revit Project (RVT).  Might make it a whole lot easier.
