    Question Help ! How to flat down a curved surface ?

    Registered forum members do not see this ad.

    Hi there ! I have finished 3d modeling a canoe in Autocad8 , she`s made of 8 curved surfaces ,and now I`m trying to “flat” them down to a single plan surface ,to get the exact dimensions so I can draw them on the plywood.It should be a simple task but I am new to Autocad8 and I could really use some help here . Thank you !

    I'd suggest using the FLATSHOT command but I'm not 100% positive it will give you the results you are looking for since all your surfaces are curved. But what the heck, give it a try.

    I had a try but the outcome is just a 2d projection , I need something like to unfold the curved surface in to a 2d plan ,without altering his dimensions . Thank you for your advice . Regards !

    A pattern or a development I believe it is called. I think you'd need Inventor or a third-party add-on to AutoCAD to achieve that result. Although, vaguely, in the back of my mind I seem to recall that there might be a third option but I cannot put my finger on it at the moment.

    Take a look at this. Not sure if it is exactly what you are looking for though.

    "Magic" buttons can be found 3 aisles over in the "Tricks and Tips" department right next to the Fairy dust.

    Really? One simple command to unfold curved surfaces. Stop nipping the grain alcohol. Time for a reality check.

    Know anyone running Inventor?

    Are you a student?

    We have a few forum members who use in Inventor. Maybe than can offer some advice.

    You're welcomed. Good luck with your canoe.

    airsoldier2001,

    We are about to complete a glass spiral staircase for a job at work here and I think this answer may help you. Your arc lengths are the key - that will be your flattened horizontal dimension.
    You should have seen me before the plastic surgery!
