CREATE PATTERN OF STAVES FOR BARREL BUILDING

[kenfrederickson]

Hi all,

I would like advice on the best way to extract a surface for patterning a stave for a barrel and for the body of a lute.

I have used sweep, and extrude, and tapered extrude, I have tried a couple of nurbs curve and loft surfaces.

also tried drape surface....I am stuck.  can anyone help?

both drawings are attached as pdf.

I am using VW 2013 in a mac.

 

thanks

Ken.

Since the edges of the staves are straight, there are a few ways to do this.

 

For the barrel, I would start in a Top or Top/Plan tool and then use the SPLIT tool to draw lines across the barrel to break it into the individual staves.

 

Same for the lute, except I would "stand it on end" like the left photo and do the split from that view.

 

Alternatively, you could make multiple copies of the original shapes and use an extrude shape (probably a rectangle) and the Subtract Solids and/or Intersect Solids commands to make the individual 3D staves.

 

You can then probably use the 3D PowerPack, Unfold Surfaces command to get a flat pattern to use.

wouldnt you just model the barrel, shell it, then split it the number of times of staves?
