Old Ironsides

sketchup 6 pro can probably be gotten by more creative means anyway. then it would probably be a matter of transerring the model file and re-saving it under the desired format.
 
Thanks for the link Damski!!! <img src="style_emoticons/<#EMO_DIR#>/biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> I'll see what I can do!

Indeed, it is a fine model. When I looked at my export options and saw what few options I had, I nearly cried!
 
Commodore, how did you make the hull curve? Sketchup refuses to do anything with the bulkheads I have.
 
the way i did it was a very tricky system of placeholders, mainly arcs. as long as you have a basic guideline, you can align the arcs along to that.
 
i'm not sure. i'll try to explain. note however, that this will not give you the hull of the constitution, but a slightly different and more modern hull. you should be able to adjust it to your liking though.

1: make the deck first.

2: (ignore this one, just some mess-up)

3: draw a line from the tip of the bow to of the stern.

4: search for the middle of the line you drew in step 3. from that point, draw a line to the side of the deck perpendicular to the line from step 3. let the line stop at the edge of the deck. do the same on the other side of the line from step 3.

5: search for the midpoint between the middle of the line from step 3 and the stern. draw another two lines there like you did in step 4. repeat for the other half of the line from step 3.

6: do the same as in step 5, but now take the midpoints between the lines from step 5 and 4, as well as the midpoints between the lines from step 5 and the bow and stern tip. you should now have eight equal spaces on your deck.

7: determine the depth of the hull. if the ship has a more or less flat keel in the middle, this is going to be a lot easier for you. take the middle of line 3. from there, draw a line downwards on the blue axis to the depth you want. this will be the placeholder for your keel.

8: if the keel is flat in the middle, just draw a flat line towards the bow and stern, for as far as you want the keel to be flat.

9: from the tips of the flat line, draw an arc from that tip to the tip of the bow and stern. that's two seperate arcs, if you didn't understand. this will be the shape of your keel. of course, you don't really have to draw an arc at the stern if you don't want to. however, this will make the ship look better in the end.

10: now, take one of crosspoints of the lines you drew in steps 4, 5 and 6. from there, draw a line along the blue axis towards your keel line. do the same for all the other crosspoints.

11: draw an arc. the first two points of the arc will be the port and starboard point of the line you drew in step 4, 5 and 6, and the third point will be the middle of the lines you drew in step 10. you should have eight vertical arcs at the end of this step.

12: draw another arc, this time from the middle of a half of an arc from step 11 to the point where a line from step 10 meets the keel. if you move around, you'll notice your arc turn light blue at a certain angle. pick this angle. repeat this on the other side and for each arc from step 11. now you should have eight ribs for your hull.

13: remove all excess lines, excepting the ribs and the keel.

14: draw a horizontal line from the back of the flat end of the keel towards the back of your ship. it won't meet the hull of your ship, of course, but this will be the area for your rudder post.

15: draw a line along the blue axis from the tip of the line from step 14 towards the back of your ship. you should now have your rudder post. add the rudder if you feel like it.

16: if you move your mouse along an arc in a rib, you'll notice that it consists of a lot of seperate points. what you now have to do is draw a line from one of these points in arc to that same point in the arc in front. do the same for the point below that point in each arc. then, draw a diagonal line between the upper point in one arc to the lower point in the other arc. you should now have two polygons which close that section of the hull. repeat this for the whole hull, closing the hull.

17: as you will have noticed, the keel is completely flat. with a bit of fiddling you can make it thicker, but i haven't done this myself.
