Bingo!

And thank you!

Sorry for the silly thing. I imported the edges (lines) from CAD and somewhere along the path I turned off the layer. I guess I should've changed all the edges to Layer 0.

Hello,

I began working on a model last night and everything was good. Today I continued with the model and I noticed a weird thing...

You know when you hide the edges of the whole model? The faces show without those pesky edges so you can visualize how your model looks with textures and stuff... Well, I haven't started working with textures yet, but after working for a couple of minutes I realized some of my solids were not showing their edges. I didn't do that on purpose, I don't even know if I did something...

I want to see the edges because these solids are not final and I need to further edit them, and without the edges, it's very difficult to do so.

Any suggestions? Also, I googled my issue and I went into wireframe mode to see if they would show up there, but they don't. Also, no luck with activating Hidden Geometry, they don't seem to be hiding, but they do exist because the faces of the solids are showing up.
