Make a sketch/extrude solid again

[Gijsb03]

I am new to Siemens NX and I have to make a Stirling engine model with NX. It went quite well until I (probably) accidentally pushed a button and my sketch/extrude became transparent like. I don't know how to fix this, I want it to become solid again (green like colour). Thanks in advance.

Hi Gijsb03,

It looks to me you changed the render details of your model. Your model is still solid, just looks different.
click and hold RMB in graphic window, choose "shaded with edges" instead of "wireframe with dim edges"

lmk if this this was the solution for your problem
