Description

System Information
Operating system:Win11/MacOS
Graphics card:RTX3080/5700XT

Blender Version
Broken: 3.0.0 Master - Caused by rB6e77afe6ec7b: Applying patch D12600, GSOC Knife Tools branch
Worked: 2.93.6

Short description of error
In the new 3.0, when the knife tool cut Sculpture or scans model, a large number of discontinuous breakpoints will appear.
When the cutting line is long, there may even be more than Dozens breakpoints, and it is difficult to troubleshoot.
In 2.93.6, there are almost no breakpoints in the same operation.

Suggest:
When the cutting tool is cutting a continuous surface, please ensure that the cutting line is also continuous, otherwise you need to check whether the line is continuous after cutting, which is very time-consuming.

Exact steps for others to reproduce the error

  • open attached file
  • make the cut as shown in the images below (make sure the middle vertex is snapped)
  • compare version 2.93 with 3.0
2.93.63.0.1
