Hello,  

I was working through the instructions on creating a 3D isosurface of the Xor label mask. When I try to "return to the Edit menu and select Isosurface Current Label and click Start", I don't see an option for this on the 'Edit menu'. 

Just wondering if I am looking in the wrong place, or if there is a step I am missing. 

Thank you for your time,
