Beautiful work. I tip my hat to you for making this great tool. This provides me with a very easy way to bring 3D Google Earth terrains into an external application. Bravo TIG!

I assume if you view the original mesh SKP in Monochrome mode with View > Hidden Geometry ON, you don't see these 'artifacts' ???

Can you post [or PM] the original mesh SKP and resultant mesh after export.
I suspect it's something to do with perhaps 'vertical' or inverted faces ?
Once we see the SKP we can hopefully find out...

Thank you so much TIG. This happens on all the terrains I've generated so far. I'm attaching the SKETCHUP file and also the CSV file that is generated from your script. Here's what the terrain looks like when I bring the CSV file into my terrain generator:

As you can see, there are pits and spikes that shouldn't be there.

I really appreciate your help as this would be an incredibly useful tool for me to have.

Many many thanks for your generosity. I sent you a donation and will encourage my compadres to do so as well.

OriginalMeshInSketchup_verts.csv

I absolutely LOVE this tool and want to thank you, TIG, for your generosity.

One thing, though. It seems that when I bring the resulting CSV file into another application to generate a terrain, I get some artifacts that seem to be almost linear whereby some of the points are too high and some too low. See the images below. The top is the terrain inside Sketchup and the bottom example is from SiteTOPO showing the sort of linear artifact lines that are showing up in my generated terrains:

I've imported files into several different applications (ARAS 360HD, AutoCAD MAP3D, SiteTOPO) and all show the same artifacts so I assume it is somehow occurring as the grid is generated in Sketchup. It is a pain to clean up the artifacts so I'm hoping somebody can help solve this for me.

Forgive me, but I am new to Sketchup. I have Sketchup Pro 8.0 and I VERY VERY MUCH am excited about your plug-in that permits export of CSV files from terrains. In fact, it is amazingly exactly what I have been looking for.

Alas, probably because I am a newbie I am having no luck getting it to work.

I installed the .rb file in the plug-ins as stated and I pasted "Exportvertices2csv.new" in the Ruby Console.

I get this result:

Exportvertices2csv.new
Error: #<NoMethodError: undefined method uniq!' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/exportvertices2csv.rb:30 (eval):0:in new'
(eval):0

Can somebody help me understand what I'm doing wrong? Could it be because I am using the Eval version? Or, am I just dumb as a rock and missing something obvious.

16Feb2014: Figured it out and am MOST appreciative of this very useful tool.
