just copy the su2kt.rb and su2kt folder, to the C:\Program Files (x86)\SketchUp\SketchUp 2014\ShippedExtensions, and it works fine.

I already solved this issue. I just downgrade to Sketchup 6 and I didn't yet get this problems, at least, in that frequency.

I didn't submit all bugs, because i got tired of it after a while.

Hi Chris, thanks to your interest.

This is a link to my model. I hope its enough to clarify this issue.

Thanks Mitcorb. I didn't know sketchup was limited to a few number of faces. Perhaps i need to model my work in separate documents. thanks again.

I use to have serious problems with sketchup crashing all the time at every operation (most of all: intersect, explode, make terrain, drape), so i used to blame my computer (4GB, dual-core pentiumm, 1GHZ), then i bought a new one (i7, quad-core 3.50 GHZ, 32 MB, garphic MSI GTX650) hoping these problems are going away, but they still. So I'm confused, is the SU full of bugs and doesn't improve the produtivity despite the hardware quality, or something else is happening?
Please, help me to clarify this issue.

ps: my text could be confuse, because i'm not an english' speaker.
