Need help Please!

roadie3rd

Hi to all
Im trying to create a sketchup model for my father inlaw who is going to be sailing from plymouth (uk) to rhode island (usa) single handed in a 20 foot gaffer rig (which he built himself) in May 2010 and he wanted something he could use as a promotion tool to raise funds for macmillan cancer support http://www.mcs-justright.org.uk/Default.aspx
Ive created the initial mesh from plans of the boat he gave me but the hull meshing is proving to be a pain

ive created a line mesh from autocad and imported it into sketchup (not a problem)
Edited it in sketchup
Then when i go to sandbox it it comes out with jagged mesh (looks terrible)
id love it if someone could take a look at my model and see if they can have any luck with it or point me in the right directionBoat Hull Model

Many thanks in advance

Seems the more speedy is redraw over with BZ spline by fredo6 (take the F SPline)
So you have just to pick the intersections or inflextions for horizontal lines!
Some vertical lines can be "weld" (by rick Wilson) by selection
Not a big deal!
in 10 minutes you can make that

Thanks Pilou tried all that but still did the same
see attached model
any other ideas?

Here is a possible approach using the plugin skin http://sketchup.google.com/3dwarehouse/details?mid=356919293504215ab9c83967811b1f7 I only selected the rails at the separation shown to reduce time because once the stitches are made the segments created will take some time to select for that tool. Reducing the number of rails and using this plugin may give you acceptable results.
Some other observation: There were 24 stray lines ( used stray line plugin) mostly where ribs are not connected to the rails and 50 broken lines. I repaired the broken lines but the sandbox tool was still giving the peaks. Don't know if the former is causing your problem; your primitives ( lines) are showing on the surrond layer. They should be on layer 0. All drawing should be there and layers only used for visibility control of groups/ components. Number of segments( 120) on the rail seems excessive to me for large radius of curvature ?
Getting late will play with your model tomorrow AM

Thanks mac1
your a star
looks good

Many thanks

Here's a quick version using my EEbyRails.
You need to simplify the 'skeleton' into profiles across the boat [bulkheads?] and rails down the 'keel' and the 'bows'.
Make each of these a curve using weld.
Try to keep the same number of segments in the profiles/rails - you haven't got that currently and a 'lumpy' mesh results where the various grouped meshed meet and need exploding together at the end...
Do a pair of profiles and rails in turn until you have completed the 'hull'.
Make it a component and mirror the halves together... boat.skp

Thanks TIG

I'm really sorry to be a pain again
This is my first attempt at an 'organic' shape and im finding it quite tricky

how would I give the hull a thickness of say 60mm to the outside edges is this possible?
If so how

Cheers Mark

Take a look at this and see if it helps http://forums.sketchucation.com/viewtopic.php?f=323&t=6708&st=0&sk=t&sd=a&hilit=joint+push+pull

Why did i agree to do this for my father inlaw
thought id get some brownie points stacked up for future use but obviously its proving harder than expected

Just so people know this is what im trying to create in sketchup

Im finding it quite hard to get the hull started. Tigs help is great many thanks and has got me started a bit but im still finding it hard to get my head round

Thanks for all the help anymore would be greatfully accepted

Cheers Mark

Ive tried this and it keeps crashing the model and shutting sketchup
i think the model is too complex and has a spas attack and closes it.
Cheers anyway is a useful plugin

What the name of the boat model?

Roadie,first of all u should be sure to find and download some blueprints(without them is very hard),then search for lot of reference images,then(but not last) u should have some average skills in sketchup..and only after these steps start building it. imho

All the best!

Or maybe you can give this a try http://www.delftship.net/delftship/index.php?option=com_content&view=article&id=31:delftship-free&catid=13:products&Itemid=4
It exports .DXF, and .OBJ AFAIK, so you can load these in SU.

Ive got the plans he built the boat to which are printouts which ive caded up the drawings in autocad. The guy who designed the boat drew it all by hand old school style and doesnt have downloadable plans. Plus you have to pay for the plans which is about £500

I have loads of images ive taken of the boat and have been given by my father inlaw

I have average skills in solidworks as i use it at work for architecture concepts but its mostly straight lines and curves not organic shapes. Ive used sketchup lots but cant get my head around the the hull shape and making it work. Ive drawn the majority of the other bits to attach to the hull but the hull is the most important bit.

Give the guy a break - he doesn't know where to start. Posting a model of a completed hull (even if it lacks accuracy) doesn't help much because it doesn't show how to set it up.
