8+ years later there is a paid Extension by Eneroth, I think Visual Merge is the name. Look in the E Warehouse.
Thanks Box,
I'll look into it. I have unsuccessfully searched multiple times for a plugin to do this over the years and now alas 5 minutes after posting I found another possible plugin (I'll test both!).

The simplest way is to edit one group and select the bottom-most geometry using a left>right fence and then Hide the selection.
Repeat for the other group... this time selecting the top-most geometry and Hide that.
Then provided that the faces of the two touching groups are coplanar and that they have the same material[s] you won't see the 'join' [unless of course you were to switch on View>HiddenGeometry...]
Sorry to resurrect this post. While TIG's method works, it is manual and slow, as you need to turn off edges in each group and sometimes break a line if only half of the line is overlapping.
If you multiply this by 100, you could see how it can slow down your workflow a lot. As an architect, I am always doing this to my models to keep the overall geometry simple.
The best solution would be a custom style, but I am not sure SketchUp can detect multiple overlapping lines.
Else, it must be possible for a ruby script that could go through a model and automatically hide overlapping lines? TIG you would be the authority on this.
Ok I also had the same problem as the Burkhard, this time with Jasons sketchup materials for arroway which also has maxwell attributes.
I fixed the problem by disabling SUPodium. If i re-enable SUPodium without any other plugins crashes return. I am using 32 bit SU8.0168 on a 64 bit Windows 7 and SUPodium V2.
Thanks for the pointers,
I tried make contour but it isnt for me as i want to retain the mesh structure.
addfaces worked to a degree, but would crash with anything but a small selection of lines with my weird mesh.
But through the addfaces post Rich pointed to, I found makefaces makefaces.rb which worked a treat except for a few non coplannar elements on the top.
So i am a happy man. 
I have been using a physics spring simulator to simulate draped fabric. It exports the springs as lines but is otherwise a fairly good mesh.
I know i can fill faces manually but as i have quite a few of these meshes it is very tedious. Does anyone know a script or trick to fill these faces automatically?
I have attached an image of one of these meshes below, it has some of my manual faces filled in.
thanks!
