Hi, I am trying to do something similar in Lightwave from a tutorial found here... http://www.youtube.com/watch?v=ho1snzDlz2M&feature=related

Here is a screen grap...

1: Spline guide of the shape
2: Spline is placed over a mesh object
3: Spline is extracted from mesh... the goal here is to ensure that the extracted shape can be sub-patched.

I am then attempting to wrap the shape extract onto a ring using lwcad.

Many Thanks

So what's the problem?

The only way I could think to do this in Lightwave is to use a boolean stencil onto the shape. It would require a lot of clean-up to make it able to be subpatched.

@3DGFXStudios I want to be able to create a clean sub-patch object from a spline like the video shows, with less clean-up.

I wouldn't do it like the tutorial says. I think in lw it's better to make the curly thing in 2D just by extending points (e) and than use the "spline guide" tool to make the thickness deformation.

Why not just use a clipmap and call it a day?

@WilliamVaughan can't use clip-map since I want to be able to send the end result to a milling machine.

gotcha... then there is really no need in making it Subpatch since it will all by Tris when sent to the machine

The base shape (without the design) is the subpatched shape from what I see in the video? You bake that shape.
Then stencil your design onto it?

Have to admit I am lost on how to do the bit with wrapping the shape into a ring.

Copy layer to bg, and freeze it. Then use Push from TrueArt's Modeling Pack, and foreground shape will match curvature of background layer. RMB to adjust Tolerance, all points should be projected in one mouse click, in top viewport (important, because Push is using viewport projection).

Thank you, Sir.

maybe I'm being an optimist but couldn't you make the "detailed-form-splines" conform to BGobject on another layer to get them to match the bending curvature of the mesh?
