    Ok - onto my next Rhino problem - you guys should work on commission!:D

    How do you go about making a surface a given thickness? Say I import a hull model (incidentally is the best way to this as IGES surfaces?) anyway - so the sides are say 50mm thick and the bottom is 75mm. Then I model the cabin - sides say 50mm thick again...
    What to do?

    Um.. Offset, Extrude Solid...You don't always need to model both sides. Most stuff normally only come off one side. Your not having 50mm cabin sides on 01 are you?

    Will,
    What Brett said, essentially, although I'm not sure why he is extruding stuff.... ;-P
    Just offset the hull, trim back to centreline if needed, and join it all up with a little skinny surface at the sheer. Deckhouse similar.
    Unless you _need_ the inner surface, I usually delete it after trimming anything against it that needs it (bad grammar, good practice )

    I mentioned extrude for things like plates with a hole in them. You can then fillet the edges easily if required. Perhaps not so applicable to a cabin top but easily applied to a bulkhead.

    Hi Will

    A variation on a theme - if applicable - is to use "offset surface" and the "solid" option (type "s" when it prompts for thickness). That would create a bowl from half a sphere in one go for example.

    hmm - seems to make sense - thanks Paul.....
    I'm really struggling with Rhino at the moment. I've done the tutorials a couple of times, but just can't seem to get the hang of it. I have a new computer arriving at the end of the week - hopefully it will be smart enough to help me out!!:D
