Yep it's that simple - duh. Sorry to trouble you & thanks for getting me on my way.

Thanks Dave

Also the other problem I have with the rotate tool is that if I try doing it manually using the rotate handle I can only rotate to an accuracy of 2 degrees - thats if I zoom way out from the drawing. If I am in close where I can actually see what I am doing it jumps from between 3 & 5 degree accuracy. I need to be able to set angles in layout more accurately than this for site set out drawings, is this a common problem with layout or one that I can resolve?

Yes - read the previous posts & have tried dragging the rotate handle clockwise & anticlockwise and corresponding positive or negative angle but same result of "invalid string". It makes no difference if the angle typed in is 90 degrees or 1 - same result.

I am also having this problem. I would like to rotate precisely but when I enter the degree to be rotated a message comes up saying "invalid string" - anyone know what is going on here?
