Hi guys,

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

http://www.youtube.com/watch?v=Kh5a0nTYldI

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!

Hi there,

Wow, that video moves pretty fast! There are a few things going on at the 1:20 mark, so I'll do my best to explain what I think this person is doing (can't say for sure because the captions aren't too descriptive and there is no voiceover).

First, it looks like the Arc tool is being used to create a rounded surface near the rear of the hull. From here, this user uses the erase tool to get rid of the surplus edges, leaving only the hull behind. You could also use the Push/Pull tool here to remove the section of the model to get at the hull in question.

Shortly after this, the modeler uses the select tool to grab the faces on the top of the hull. To select both faces, use the select tool to double click each face (holding shift while doing so); you should see both the faces and the edges highlight blue. From here, use the Move tool and hold down alt/option (on Mac) to create a copy of that face; use the mouse to raise up this copy along the blue axis and voila!

Both of these processes can be done in the free version of SketchUp. I hope this helps -- in the future, if you have questions like this, you might want to check out the SketchUp Help forum (http://productforums.google.com/forum/#!forum/sketchup) or the SketchUcation forums (http://sketchucation.com): those are two good places to find answers to SketchUp questions!
