What exactly are you trying to do? Do you want to rotate multiple objects at once where each object is rotated around its own placement point but in the same direction as other objects?
Interesting question... Not of the top of my head unless you are setting up some sort of an angle rotation type parameter. What kind of elements are you trying to rotate?
i have inport and exploded a cad file, but the problem is that the cad file is drawn in a different orientation from my model, so i have rotate the drawings to match my orientation but the problem becomes that the text now becomes vertical
Don't import and explode an AutoCAD file inside Revit. A big no-no. Link it into Revit and use it as a reference to create your text using Revit, and then remove the link when you're done.
You can achieve this in microstation. There's a option to rotate about center of element. I haven't figured this out yet, have you found a solution yet?
select the (multiple) elements you want to rotate, dont specify rotation point, instead just input the angle you want (180 for me) and enter. They would rotate on their own center points.
