3DS max Doubled edges

Filip5

Hey guys, having some problems with doubled edges on my model. No idea how I got them, as I created plane and just extruded it and moved around vertecies. Yet, for some reason it created double edges, which causes problems with geometry. Interesting is that it doesn't need welding. How do I get rid of them, and how can I prevent creating them in future ?

P.S. - I know of backspace, but this doesn't work. Deleting the edge either removes edge itself, but creating another one next to it, or deletes whole face.

Coplanar face. Just happens sometimes when modeling. Either delete the back face or delete both and cap the border, and then run low threshold weld on all surrounding verts just in case. You should be able to tell if there are more when you select the border as it will not be closed and other edges will be selected as well.

I turned on backface culling. According to that, there are no back faces.  Also, welding with ammount of 0.1 does nothing.

apply an edit mesh modifier and collapse to editable poly , see if it fixes it

I don't think it did something. Actually, I am posting max scene, you can see for yourself. Upon sellecting all edges and hitting backspace, many still remians... Wich is weird, because I only extruded plane troughout the whole process

musashidan is correct. Faces on top of each other. You can examine your mesh for errors using the xView dropdown.

Didn't know about this in max. Thanks monster. Just a question, how to fix this. By selecting face, deleting it and using bridge on edge creates another overlaped face. Is there any auto function on this ?

First picture is after clearing those overlaping faces. Just by using bridge on edge creates this mess again





PS - Oh, my bad. After connecting edge, max switches to face, one have to switch back to edge. Thanks guys

Hovewer, just extruding edges automatically creates doubled faces... This software is making me mad...

PS - Started all over again, still the same problem. Even if everything is alright, extruding edge by 0/0 creates overlaping faces all of a suden. Any solution for this ?

That is behaving as designed. Extrude creates new geometry and pushes it out. If it has a low value it won't push it out very far, leaving you with overlapping faces. 

What are you expecting extrude to do?

Or what are you trying to accomplish?

Just trying to create shape of vehicle by drawings. Nothing hard about. Hovewer, it seems just by welding all vertices belonging to overlapping faces solves this issue.
