rotate an imported dwg object

[p.vicini]

Somebody knows how you can rotate an imported Dwg alligning it to another object in a Revit project, whitout know the rotation angle between them?

[gravelin]

First, move the DWG from a reference point in the DWG to a reference point on the object on witch you want to align (use move command)
Second rotate the DWG :
place the rotate center on the reference you've choosed
then pick on the object you want to align in the dwg,
pick to the object on witch you want to aligne in the project

et voilà
