Strange split error

hi guys, i’m getting an error when i try to split my surface. could you please take a look at the images below and let me know what is going on here. the surface doesn’t split properly and a strange stepped artifact is produced ( i am attempting to split one petal down the middle)

Hello - please post a file with the two surfaces you’re working with, I’ll take a look.

Hello Pascal,

Thanks so much for offering to take a look.

Basically what I am trying to do is joined the petals on each layer
together so they don’t intersect (like I have done with the “bottom
layer”). There may be other ways of doing this…

I have attached the file below
lotus petal cut attempt.3dm (1.1 MB)

Hi Christian - try -

  • UntrimBorder that one petal that has strange isocurves and shading.
  • Select the petal(s) and use CutPlane from the top view to make a cutter. Make two planes, one for each edge of a petal.
  • Split the surfaces.
  • ArrayPolar the result.

-Pascal

of course !! excellent suggestion. that worked perfectly. all i needed was
the advice of a pro. thank you !
