Hi guys,

I'm trying to model boats in Google SketchUp and have been stuck for a long time now. Please see this video:

At 1:20, the uploader is able to push off the top off the hull from the rear part of the boat, creating a nice round surface. I simply cannot do this. It refuses to move. I cannot push the rear part off it. I also tried to create an exact copy of that same curved line line, both by copying it, and by following the measurements, in order to erase the old lines and create a new surface, however it won't cover/create a surface. I'm stuck!

I use the free-version of SketchUp. This shouldn't matter though I believe?

Any help is appreciated! ...And yes, I've tried to google it! Thanks guys!
