rotating parts in Slic3r

Guys, I have a part that I want to print upside down using Slic3r and Pronterface, but no matter what I try I don’t seem to be able to get a rotate command, or even a view that allows me to rotate

Which is the command I should be using?


Right click on the part and use the “flip” command, typically I have to use flip around the x-axis, but it just depends on which way you want to flip your part.

Right mouse click on the model does not give you the rotate/flip/duplicate/scale/… Menu ?

I should have said that I do this in Slic3r (Version 1.2.9).

Thanks guys, will wait for the current print to finish and try it
