I dont know how the grid got switched off and i don't know how to switch it on.

I thought about the constrained part that the circle may not be constrained..but when i do so ansys does not constrain it well 

see this

the center is at 0.398mm whereas the line is at 0.4mm

i want that 2micro meter distance between them (this is one of the reasons i stopped making the model solidworks thinking space claim will give me a better model)
