Hello you all.I've got a little problem on autocad.i have to rotate an object, in this example a triangle.i can usually rotate the object around the point where i click, but now i want that do it AND the tip of triangle must go in the correct position.see the image to understand.A should coincide with B.Sorry for my uncorrect English!

Either try the Reference option of the ROTATE command, or the ALIGN command.

Yes! it works fine!thank you very much Vladimir!Bye
