creating a curved surface on extrude.

[ldillon]

Hey, I am currently using Creo parametric to design the top plate of an acoustic archtop guitar. so far I have managed to make the basic shape by extruding a drawing. To create the necessary convex surface I tried using the revolve feature, this method did not work as the revolve could not follow the pattern of the drawing. I have attached photos for my design so far and a picture of how it should look. Is there any way of making a revolve which will follow the the shape of the extrude ? If not how can I create this design ?

That shape, from what little I can see in the pics, cannot be created by simple Boolean shapes.  Learn advanced features and surfacing. 

Nice guitar though......

Thanks for the reply ! Do you have an idea of which techniques I should use ?

Once you master the variable section sweep, this becomes pretty simple.

But Frank is right, there is no one magic feature that creates a masterpiece.

Creating a domed surface is not hard.  In its basic form, a revolved arc and a trim to square will do it.  The trick is maintaining the sidewall length uniformly or intentionally formed with regard to the periphery.  This is where the advanced surface module is a useful tool to help keep continuous surfaces.  No guarantee, of course, but about 10x easier than with core Creo.

Also have a quick look at freestyle.  You might be able to manipulate a blob into something useful that can be trimmed away or merged with a solid.
