Curves

To preserve curve direction u must preserve vertex order.

SOP

  • curve node

…

  • resample
  • refine

Cut on point

  • Convert Line redraw primitive (destructive for gr &atrr)
  • Carve (will disconect points ! )
  • Poly Path redraw primitive (destructive for gr &atrr)
  • Resample Redistribute point and attribs alobg the spine (blend attribs)
  • Poly Cut can cuts only on points (detroy point grups )
  • Fuse

Inject edge where is no point

  • Boolean
  • Poly Split
  • Clip
  • Knife
  • Intersection analysis
  • Incrementersection stitch

Labs tool

  • Poly Slice make points on curve or prim > slice / preserve edge group & curve dir. snap.
    Based on:
    • poly split
    • boolean (faster)
  • Merge Splines - with specific conditioons.
  • direction ???
  • Poly Wire UV !!!! - «<

NURBS & B splines
